1.
General
1.1 Scope
The following documentation is intended to be a reference document to aid in the setup and
installation of the robotic servo weld guns for all projects using servo guns and Fanuc SpotTool+ 8.20
with the GRS4 Customization. This documentation is intended to detail the steps necessary to install
a Tolomatic servo weld gun on to a Fanuc R-30iB robot controller. The steps outlined in this manual
will allow the intended audience to install the weld gun, calibrate, tune, and program/touchup weld
paths.
1.2 Purpose
The steps outlined in this manual will help to ensure that all servo weld guns are integrated
and setup in the same fashion so that the system is easily maintained and is fully functional to all RS
specifications as well as GCCS-2, and GCCH-1. This document is not intended to replace servo gun
manuals from Fanuc, but to simply document specific setup criteria specific to General Motors
applications, using Fanuc SpotTool+ 8.20 with the GRS4 Customization.
1.3 Intended audience
The intended audience for this document includes robot programmers, engineers, and skilled
trades responsible for setting up the servo gun robots at integration, and maintaining the equipment
once it is installed into the production environment.
1.4 Background
The servo guns that are being referenced use a Tolomatic/Aro3G motor that incorporates a
Fanuc encoder, and connectors that allow it to be controlled by the Fanuc robot. There are 7 different
motor sizes.

FANUC ACa8/4000is-40A/80A
REQUIRES WATER for Operation.
All motors are driven by the same 40 amp auxiliary amplifier in the robot, as an integrated robot axis.
The basic setup has the robot arm as motion group 1, and the servo guns as group 2, and group 3 if
necessary. The control of the servo gun is integrated into the robot system, such that I/O is not
necessary to control the gun functionality, such as backup or equalization. All configured spotwelding
guns in the GM GRS4 customization will require water flow for STROKE operation.

Gun Installation
2.1 Gun Mounting
When mounting the gun to the robot faceplate, care should be given to the way the
connectors for the motor will route. There are 2 connectors that are used to control the Tolomatic
motor from the robot. The first is the power cable and the second is the encoder cable. These
should be positioned such that the cables and connectors are in the safest location relative to
projected path. If there’s interference it is possible to rotate the motor end cap +- 90 . See motor
documentation on rotating the connectors on the end cap.
3
Wizard Setup
The wizard allows the robot software to be configured for the specific application. The
programmer needs only answer a few questions and the software configures itself based on the
answers chosen by the programmer. This functionality has been further enhanced to include setting
up of the servo gun applications, including group and axis data that previously needed to be done
manually before running the wizard. This presented some complexity issues and has been remedied
by adding the necessary functionality to the wizard. If the application is SERVO TOOL CHANGER
please refer to Section 16 and 17.
3.1 Getting Started
Before running the wizard, some information regarding the robot and application need to be
gathered. They are as follows:
1. Robot software version.
Must be 8.20Pxx G3 03-14-14 (Update 00) or later.
An update will be necessary if the software is not up to this level.
2. Information about the application that the robot performs
Carried or Pedestal Process
3. Information about the servo guns
Motor Type
Maximum Force for the gun (NOT the maximum motor force)
Net Gear Ratio (NOT the motor ratio)
Maximum gun opening (NOT the maximum motor stroke)
Gun type: Pinch/X-style or C-style
Auxiliary Amplifier that the servo motor is attached to
4. Information on how the guns are going to be used (If multiple guns exist)
1. Dual gun single equipment
2. Dual gun Dual equipment, 1 or 2 weld controllers
a. Affects tip wear compensation and pressure schedule approach.
If the appropriate groups are not present when the wizard is run, the wizard will automatically
add the Servo Gun group and then boot back to controlled start. It is important that a full load USB
memory device with the AP1 directory be plugged into the controller when servo gun groups are
added. Once the robot has returned to Controlled start it will be necessary to re-run the wizard to
configure the robot application. To see an example of running the servo gun setup wizard please
refer to the 8.20P-xx Wizard manual-GM Customization document.

3.2 Helps and Hints
3.2.1
Re-Running the wizard to correct for an incorrect response during initial setup
If a mistake was made in the initial setup of the wizard, the easiest way to recover is to re-run
the wizard. This will allow the robot to automatically reconfigure for the change. There is no need to
reboot back to controlled start if you are currently at controlled start. Simply rerun the wizard, making
sure to take your time. It is necessary to set Cell I/O every time the wizard is run as the robot resets
the cell interface to default when the wizard is launched.
3.2.2
Re-Running the wizard to add a feature
If it is necessary to add a feature such as a tip dresser or Transformer Over Temp switch, it is
not necessary to re-run the wizard completely. It is necessary, however, to Boot to Controlled start
and launch the Wizard. Select Item #3 ‘Add to Configuration’. This will allow the user to add the
necessary items, without having to run through the entire wizard. Prior to adding a feature, it is best
to back up the robot, in the event an error occurs. A backup all is sufficient
1. Perform a Backup All of the controller
2. Perform a Controlled Start
3. Start the wizard
a. Select Option #3 ‘Add to Configuration’
i. Follow the prompts as necessary
4. Perform a cold boot
5. Query any new DeviceNet nodes as necessary.
4
Establishing Pulse on Servo Gun Motors
Once the groups and axis are configured and the wizard run, it is necessary to master the
guns. This procedure is critical and must be followed as outlined below for each configured servo
gun.
4.1 Resetting BZAL (Battery Zero Alarm)
As is the case any time a motor is installed on the robot it will be necessary to clear the BZAL
alarm that indicates that the system has lost communication with the encoder.
The steps necessary for clearing the BZAL alarm:
1.
2.
3.
4.
5.
6.
7.
Press [MENUS] -> [NEXT] -> [SYSTEM] -> [Master/Cal]
Press [FCTN] ->[3: CHANGE GROUP] (Select the Servo Gun group, either 2 or 3)
Press [F3: RES PCA]
Select [F4: YES] when prompted to ‘Reset pulse coder alarm?
Repeat steps 2 and 3 for all servo gun groups.
Cycle the power on the robot controller.
SRVO-075 Pulse not established will be displayed in the fault log upon power up.

Global 3 Servogun Setup Users Manual for Fanuc SpotTool+ 8.20 with
GRS4 Customization
4.2 Establishing Pulse
Before the Gun can be mastered it is necessary to establish pulse with the Fanuc Encoder
that is mounted in the Tolomatic motor.
4.2.1
GSWA and SW-Series Motors
The method used to establish pulse on the SW series motor is identical to the method used
to master a standard Fanuc motor.
1. Select Group 2 for equipment 1, Group 3 for equipment 2
a. Press [FCTN]
b. Item [3: Change Group]
2. Jog Servo Gun axis until pulse is established. (The robot may indicate on the teach
pendent that 'Pulse has been Established')
a. Jog the axis in both the +X and -X direction until 'Pulse is
established'
b. For a second gun on that equipment jog the second axis in the +Y
and -Y direction until 'Pulse is established'.
4.2.2
HT-Series Motor
For the HT-series motors, because they are 4-pole rather than an 8-pole require an additional
step to establish pulse with the encoder. It is not possible to immediately jog the axis without
manually rotating the motor by hand.
To establish pulse on the HT-Series motors it is necessary to perform the following for each gun:
1. Locate the manual override key/gear on the servogun actuator.
2. Loosen the cover and slide out of the way. (Do not remove completely)
3. Using a screwdriver carefully rotate gear one complete revolution.
4. Attempt to jog the gun.
i.
If successful, the gun will move, and the gun can then be mastered
ii.
If unsuccessful, the robot will still indicate a pulse not established alarm.
Repeat step 3 and 4 until successful.
5. Replace cover on manual override access.

5
Mastering the Gun
This is the recommended method to master the weld gun, because it calibrates the axis
automatically and sets the servo gun limits to the limit defined in the Wizard setup at controlled start.
This method also verifies that the gun close direction is correct such that there is commonality among
all guns and for the capability to download simulations.
To access the Gun Setup and Autotuning screen:
Press [MENUS] -> [Utilities] -> [TYPE] -> [Gun Setup]
The following
steps must be
completed in
order.

Global 3 Servogun Setup Users Manual for Fanuc SpotTool+ 8.20 with
GRS4 Customization
5.1 Setting Gun Close Direction
The first step in calibrating the gun is to set the gun close direction. This is to set the robot up
such that +X on the teach pendent closes the gun. Follow the directions and then proceed to the next
step.
1. Select [Set Gun Motion Sign], and follow instructions
Note:
For all GM servo guns we want +X to close the gun tips and -X to open the gun (+Y/-Y for the
second gun on the same Group Axis). If this is not the case, as with reverse parallel guns, it will be
necessary to go into controlled start and to change the motion sign under the axis configuration from
False to True. This should only be the case on reverse parallel guns.
5.2 Mastering the Gun and Setting Axis Limits
5.2.1
Single Gun per Equipment
1. Select [Set Gun specs, master gun]
11

GRS4 Customization
2. Answer [YES] When prompted if you know the gun’s tip displacement of the gun
(Gear Ratio from the gun tag)
3. Answer [YES] When prompted if you know the gun’s stroke limits (Max Open
Distance from the gun tag )
4. Follow the directions to master the gun and set limits
5. Close the Gun until the caps are touching and Press [F4:Closed]
6. Enter the Tip Displacement (This is the Value that was entered in the Wizard at
controlled start)
This will actually
master and calibrate
the gun at once,
allowing you to jog the
gun open to the axis
limit that was set off
the gun tag at
controlled start.
7. Enter the Open and Closed limits for the weld gun.

5.3 Autotuning
The purpose of Autotuning is to have the robot calculate certain properties of the weld gun
that are necessary for proper operation. This operation must be completed prior to pressure
calibration, tip wear setup, or any of the following sections. Autotune must be run for each servo gun
separately. It will be necessary to cycle power after running Autotune before the next gun can be
tuned. All guns should be mastered prior to Autotuning any gun.

Pressure calibration
Once the servo weld gun has been mastered and Auto Tuned, it is necessary to perform a
pressure calibration on the system such that the robot can determine the relationship of motor torque
to tip force. Pressure calibration will need to be carried out for each servo gun.
6.1 Equipment
To perform pressure calibration you will need the following items.
1. Calibrated Pressure Gauge set to tracking force rather than Peak especially for C-guns.
2. Force gauge holder assembly
a. This allows for one person pressure calibration by fixing the force gauge to the
stationary gun arm so that the operator has both hands free to run the pressure
calibration from the teach pendent.
b. It is not recommended to run pressure calibration without this assembly because it is
too cumbersome to hold the force gauge and execute the pressure commands from
the teach pendent.
NOTE:
Because the weld gun is an additional axis to the robot, this task must be performed with servo power
available to all robot axes.

6.2 Performing Calibration
Pressure calibration is to be performed in T1 mode at 100% override. This is possible
because the force calibration takes place at 50mm/s, which is less than 250mm/s.
The following are the steps necessary to calibrate the weld pressures on a servo gun:
1. Press [MENUS] -> [Setup] -> [Servo Gun]
2. Select <*DETAIL*> under General Setup
3. Select <*DETAIL*> under Pressure Cal: (Should show INCOMP)
4. Select [F4:Yes] when prompted to start pressure calibration
5. Select [F4:OK] to acknowledge the torque limit note
6. Verify the following settings
[Pressuring Time (sec)] = 2.0
These settings are for the

gun.
9. Attach the force gauge to the stationary arm of the weld gun such that the gauge face is
resting on the stationary tip.
10. Enter initial torque % for first pressure calibration test. 5% is a good starting point.
Enter Torque

Speed Value may change
11. The speed value may change when you enter the Torque percentage. This is new for
Spottool+8.20 and Global 3 robot. This speed value is now calculated automatically
during the auto tuning process.
12. With the robot servos reset press SHIFT-[F3: Pressure] to have the robot close the gun at
whatever torque was specified. (Cursor must be on the line for the requested torque)
13. Step A. Adjust Torque (%) up or down until the desired force is achieved. When
pressure calibrating some C-Type guns, lowest pressure may require torque
percentage to be as low as or even lower than 1%. This may result in unreliable
pressure readings. Again, make sure the force gauge is set for Tracking Mode.
Contact the MAAC lead engineer if Torque Percentages are less than 1%.

Step B. Switch the force guage to Peak Mode and with the robot servos reset press
SHIFT-[F3: Pressure] to have the robot close the gun. Record the peak pressure. If the
peak pressure is greater than the targeted pressure, this gun is experiencing significant
amount of friction. Peak values above 2000kN are abnormal and could cause damage to
the Tipdresser. Contact the weld gun engineer to service gun before proceding with the
gun setup. Note some guns may need to exercised to break them in. After the gun has
been serviced or broke in, rerun Autotune and begin pressure calibration at step 1 again.
Torque can be
adjusted in 0.1%
increments
14. Repeat steps 9 – 13a for each of the pressures in the table up to the maximum rated
force of the gun. Make sure not to exceed the rated force for the gun. The motors
are stronger than the guns.
If the necessary torque required to reach a required force exceeds the
allowed torque (Max Gun Toque (%)), it will be necessary to exit pressure
calibration by setting pressure calibration complete, and accepting/updating
the torque limits when prompted. This will update the over-torque limits. To
complete pressure calibration simply restart pressure calibration and the
limits will have been increased, allowing for the completion of pressure
calibration.
15. When torque values have been entered for all valid pressures in the table, change the
Calibration Status to complete.

4. Pressure gauge shows radically different pressures
Increase Pressuring time
5. Gun cannot achieve the lowest requested pressure in the calibration table.. This could
be indication that the gun is experiencing higher than normal friction. Accept the lowest
attainable pressure with the guage in tracking mode. Complete the remaining pressure
calibration targets ,then review the details of servo gun overtorque protection
menu(Section 7.0). If the Standard overtorque value exceeds 1400 torque counts the
gun mechanism is experiencing higher than normal resistance during and must be
checked for the following:
C-guns need the gun slide/carriage bearings aligned.
X-guns could binding in the gun pivot bearings.
A failing servo actuator.
Notify the project weld gun engineer, if you determine any of these issues.
6. Requested Torque % exceeds limit and Pressure calibration cannot be performed
This occurs when attempting to calibrate a torque that is greater than that specified
under Max Gun Toque (%). This can occur because the values that Fanuc defaults
to are conservative and assume full mechanical advantage.
1. To allow calibration to use torques greater than max torque it is necessary to
exit pressure calibration by setting pressure calibration complete and
accepting/updating the torque limits when prompted. This will update the
over-torque limits.
2. Restart Pressure calibration and the limits will have been increased, allowing
for the completion of pressure calibration.

Overtorque Protection
Servo Gun OverTorque protection is part of the Servo Gun Software Option. OverTorque
Protection is designed to reduce the damage to servo guns and servo gun actuators cause by
excessive tip force. OverTorque protection monitors the motor current on the servo gun axis to
determine if an unexpected disturbance is present. It then removes servo power from the motor and
post a “Collision Detect Alarm” when a potential over torque condition is captured.
OverTorque Protection is enabled by default with a sensitivity of 100%. To optimize
OverTorque Protection the sensitivity can be increased to a max of 200% or decreased to 1. Note
that the sensitivity can only be decreased to the max force of the gun. Sensitivity can only be
modified after the servo gun has completed the Autotune process.
It is important to view the Standard Overtorque value after Autotune and Pressure calibrating
a servo gun. This value is an indirect measure of the friction in a gun as measured during Autotune.
The peak value is captured during the Autotune process. Guns that exhibit high Standard
OverTorques are subject to momentarily achieving higher than desired tip forces. This is a result of
the gun needing a large amount of torque to move, and in some cases this torque due to friction can
be larger than the desired welding or tip dress force. If this value is greater than 1400 torque counts,
this condition exists. It is normal for new guns to experience a break in period and they should be reAutotuned and re-pressure calibrated after being broke in. Guns with Standard Overtorques above
1400 torque counts should be evaluated for mechanical issues.
To view the Overtorque Protection Menus and the Standard Overtorque value use the following
procedure:

Tip Wear Compensation
Because the GM Global weld guns do not include equalizers, it is necessary to program the
stationary tip touching the metal. As the stationary tip wears through welding and tip dress, it is
necessary to determine the amount of tip wear present on each tip, and to offset the robot path to
keep the stationary tip in contact with the part throughout the life of the cap. To enable this, the robot
has certain macros that setup the tip wear compensation, and other macros that will calculate the
wear throughout the life of the cap.
There are a few things that must be remembered when running with tip wear compensation
enabled. First is that after changing the caps on the robot, it is necessary to update the tip wear,
telling the robot that it has new tips. If this is not done, the robot may bend the flange with the
stationary tip, causing damage to the part, gun, or causing collision alarms.
9.1
Setup
To setup Tip Wear Compensation it is necessary to enable compensation under Servo Gun
Setup, and to run the respective setup program for the configured servo guns. For dual guns on a
single equipment tip wear compensation is enabled or disabled for both guns
9.1.1

Running Tip Wear Compensation Setup Program(s)
To run the tip wear setup program, simply select the appropriate setup program and run the
program from the teach pendent. Be sure that new caps are firmly seated on the gun before running
the tip wear setup routine. TW_SETGx will take the gun stroke limits from the gun setup utility to
reference cap wear. If TW_SETGx is run any other time, verify that the servo setup gun stroke
limits match the gun stroke utility setup screen. If they don’t match, manually enter the proper
stroke limits on the stroke limit screen under MENUS/SETUP/SERVO GUN/GUN STROKE LIMIT.
Note: If the robot is a Tool Changer TW_SETGx is replaced with TWSTGXTC
The setup programs (macros) are as follows:
TW_SETG1.TP
for Gun 1
TW_SETG2.TP
for Gun 2
TW_SETG3.TP
for Gun 3
TW_SETG4.TP
for Gun 4
The tip wear setup program for Tool Changers is as follows:
TWSTGXTC.TP
for R[13:Current Head]
9.1.3
Wear Ratios
The wear ratio is the ratio of wear between the stationary tip and moveable tip. It is set
relative to the stationary tip. Therefore a wear ratio of .4 is 40% of total wear is relative to the
stationary tip and 60% to the moveable tip. Each gun has its own wear ratio, and they are set via
registers for ease of use. By default all ratios are set to .5, or equal wear for each tip. Based on
metal stack-up and coating they can be adjusted to better reflect the actual wear ratio.
The tip wear ratio registers are as follows:
9.2
R[5: TW Ratio fix G1] = .5
R[6: TW Ratio fix G2] = .5
R[7: TW Ratio fix G4] = .5
R[8: TW Ratio fix G4] = .5

9.3
Tip Wear Updating
Once tip wear setup has been completed, the robot will periodically update the tip wear value
by running a tip wear routine that will close the gun and determine the total amount of wear. It will
then apply the tip wear ratio in splitting the wear between the moveable and stationary tips. The
standard software is configured to update one gun every cycle. For a single gun case, it will update
every cycle, and for a four gun case it will update each gun every 4 cycles. There is a register in the
robot that keeps track of the last gun updated and indexes to the next gun automatically.
9.3.1
Tip Wear Routines
There are several programs that are run to perform the necessary tip wear functionality. For
the most part the operator will need to do nothing with these routines as they are nested into
the code, but are listed here for completeness.
9.3.1.1
TW_GUNS(x) x= gun number
This program is run whenever the steppers are reset, or whenever new caps are placed on
the robot. This routine calls TW_UPDCC(x) for the specified servo gun.
9.3.1.2
CAP_WEAR
This program is run every cycle to update the tip wear on one of the servo guns. This routine
is typically run on the way home after entering segment 63 (clear of transfer) or during a
drop-off for a pedestal application. This routine will only update a single gun every cycle
because of the time involved ~ 4 seconds. With that said, each gun will update every 4th
cycle worst case.
9.3.1.3
TW_UPDT(x)
x= gun number
This is the routine that Cap Wear calls to update the wear on a specific gun. This routine is
also called outright to update a specific gun by the tip dress routines. When this routine is
run, it will close the selected gun and measure the tip wear from the original position that was
recorded when Tip Wear Setup was done. This routine expects that each successive
measurement will show increased wear. This routine will allow the caps to grow by a small
amount (configurable) in case of a 'Cling-On' during a tip dress.
9.3.1.4
TW_UPDCC(x) x= gun number
This is the routine that TW_GUNS(x) calls to update the wear on each gun. When this
routine is run it will close the selected gun and measure the tip wear from the original position
that was recorded when Tip Wear Setup was done. This routine expects the caps to grow,
as expected with new caps.
9.3.1.5
TW_REG(x) x=gun number
This routine was added to provide enhanced servo gun tip wear information. It updates the
amount of wear during the tip dress and posts the servo gun tip approaching max wear
warning bit.

9.3.1.6
WR_UPDAT(x)(y) x=gun number y= new tips flag
This routine updates or resets the tipwear values.
9.3.1.7
CHK_WEAR
This routine checks the tipwear values and compares them to the last known wear values to
determine if the caps were changed on a particular gun. It checks every configured gun.
This program is called from TIP_RST and is executed prior to resetting the steppers and
wear.
9.3.1.8
TW_GNRST
This program is called from TIP_RST. The program calls TW_GUNS(x) for any configured
gun that has a cap change request and different set of caps as determined by CHK_WEAR. If
different caps were detected without a cap change request or a cap change was requested
with the same caps are detected by CHK_WEAR, the user will be prompted for direction.
9.3.1.9
GET_CFG
This Karel program was developed to check the configuration of the robot to aid in the cap
changing process. It does this by gathering the cap change requests from the PLC or by
prompting the user if TIP_RST is ran manually from the TP. It is called from TIP_RST.

Set Gun Close Direction
The gun close direction defines direction the tips move to close and weld. For the
moveable tip which the Fanuc software refers to as Gun, should be set to PLUS, indicating
that the positive displacement of the moveable tip closes the gun. For the Stationary tip,
which the Fanuc software refers to as Robot, needs to be set to indicate the direction that the
TCP must move to bring the stationary tip to the work piece. This setting is critical, because
it determines the direction the robot will move to place work piece on the stationary tip as it
goes through the motions that encompass a weld with a servo gun.

Pressure schedules
General Motors has standardized the Pressure Schedules that are to be used for all servo
welding applications. These 16 pressure schedules are not to be modified, because they include the
best compromise between speed, performance and complexity. If a need arises that requires a
unique pressure schedule, it will be necessary to add a schedule. However, this will require buy-in
from the lead robot and welding engineers due to the fact that it affects the weld spot verification
process, and leads to uniqueness, and added complexity.
12.1 Background
The pressure schedules in the robot controls more than just the weld pressures, it also
controls the way the robot approaches a weld and departs after a successful weld. There are 99
pressure schedules available for each gun. The elements listed below are available for each of the
99 schedules.
To access the pressure schedules in the robot:
1. Press [Data]
2. Press [F1: Type] -> [Pressure]
1. Setting
Manual=True will
cause the specified
schedule to appear
in the select list
when the [Gun] U1
key is pressed by
the user
Verify
These are the
default
pressure
schedules for
all robots. Only
the forces up to
the max rated
force of the gun
will be present
2. Pressing [Gun] (nonshifted) U1 will
select the next
Pressure Schedule
in the list that is set
TRUE
3. Pressing [Shift] [Gun] U1 will cause
the weld gun to
move to close at the
defined pressure
Note: When validating pressure schedules, it is important to do so with tryout mode

12.2 Elements
There are 4 elements to each pressure schedule that need to be set correctly for the servo
guns to operate in an efficient and effective manner.
1. Weld Force
The amount of force the gun will apply before welding.
2. Gun Sag
The amount of deflection (flex) on the stationary tip that is caused by closing the gun
to the prescribed pressure.
3. Pushing Depth
The maximum distance that the robot will push to build pressure.
4. Contact Speed
The speed at which the welding electrodes will contact the work piece.
12.2.1
Weld Force
The weld pressure is the tip force (weld pressure) the robot will apply before initiating the
weld controller.

12.2.2
Gun Sag
The servo gun has the ability to compensate for gun deflection as the weld force increases,
allowing the stationary tip to remain in the same position as the force increases. This is especially
important on C-Guns where the stationary/fixed gun arm wants to deflect under load. By setting up
gun sag, the robot can move the stationary/fixed tip in the opposite direction of deflection, allowing for
a consistent weld location without the use of an equalizer. This is especially important because the
C-Guns do not incorporate pneumatic or spring equalization, with the exception of dual guns and hard
automatic fixture guns.
12.2.2.1
Enabling
The Gun Sag Compensation must be enabled for the robot to compensate for gun deflection.
1. Press [MENUS] -> [Setup] -> [Servo Gun]
2. Select <*DETAIL*> under General Setup
3.
Select Enable under [Gun Sag Compensation]

Setup
1. Make sure that Gun Sag Compensation is enabled
2. Verify that the gun sag values are not 0.0mm in the pressure schedule detail page. [Gun
Sag Comp Value (mm)] will be calculated automatically from data taken during
Autotuning, and will be automatically filled into the pressure schedules once pressure
calibration is complete.
This value is
calculated
automatically after

12.2.2.3
Pushing Depth
The pushing depth indicates how far the robot will move past where it expects to build
pressure, before it faults with a pressure shortage. For example if the part thickness is set to 3mm in
the SPOT statement (SPOT[SD=10,P=1,t=3.0,S=1,ED=10]), the robot expects to build force when the
tips are 3mm apart. The pushing depth feature allows the robot to search past this point to build
pressure so that minor variations in part thickness to not cause nuisance faults. The default pushing
depth for all pressure schedules is 6mm.
To access a pressure schedule in the robot:
1. Press [Data] hard key
2. Press [F1: Type] - > [5: Pressure]
3. Cursor to select desired schedule
4. Select [F4: Detail]
5. Cursor to pushing depth to modify
Pushing depth is
6mm for schedules
1-16
12.2.2.4
Contact Speed
Contact speed indicates the speed at which the welding electrodes will contact the work
piece. This value by default is the speed that was used during the pressure calibration of the servo
gun. This value should not be adjusted except for certain applications such as tip dress that a higher
or lower contact speed is desired for the process.
Note:
Increasing the contact speed higher than that used for calibration can lead to a higher force
deviation from that calibrated.

Backup schedules
The robot has the ability to program backup positions that specify how much the gun is to
open when the specified Backup schedule is called. This offers a simplified method of
programming gun open positions, without requiring the user to jog the weld gun axis. The backup
command can be added to the standard SPOT instruction, or executed as a manual function using
the Backup Key.
There are 30 backup schedules that can be programmed for each gun.
To locate the Backup Data:
1. [DATA] -> [F1:TYPE] -> [6:Backup]
1. Setting Manual=True will
cause the specified gun
open distance to appear in
the select list when the
[BACKUP] U2 key is
pressed by the user
2. Pressing [BACKUP] (nonshifted) U2 will select the
next Backup position in the
list
3. Pressing [Shift] [BACKUP] U2 will cause
the weld gun to move to
the currently selected
Backup position
The Backup Schedules are pre-defined in 10mm increments. This will allow for easy
assignment of Backup Schedules without referring to the backup data. I.e. Backup No. 1 is 10mm,
BU #2 is 20mm, BU #15 is 150mm and so on. This table can be adjusted as necessary for specific
applications, but should be fine as is, with the operator setting Manual = True for those positions that
they want to access from the Backup Key.

Distance Schedules
The robot has the ability to program distance schedules that specify how close the gun is to
be to the work piece as it approaches a weld. The associated parameters are for Gun (Moveable)
Robot (Stationary) tips. These distance schedules are used in the SPOT instruction to determine the
position the robot moves the caps to prior to and after a weld. All values are in addition to the part
thickness. So if you are calling a SPOT instruction with a pressure schedule that is 3mm, and you
use SD (Start Distance) =4, the tips are 11mm apart. 4mm above the part and 4mm below the part.
The same applies for ED (End Distance), which is where the robot will move the gun to after the weld.
L P[2] 1500mm/sec CNT100
SPOT[SD=4,P=1,t=4.5,S=1,ED=4] ;
There are 99 distance schedules that can be programmed for each gun.
To locate the Distance Data:
1. [DATA] -> [F1:TYPE] -> [Distance]
The Distance Schedules are pre-defined in 1mm increments for distances 1 thru 20 this will
allow for easy assignment of Distance Schedules without referring to the distance data. I.e. Distance
#1 is 1mm, Distance #10 is 10mm and so on. Distance Schedules 21-34 range from 40mm-320mm,
this allows for multiple open distances for the moveable tip.

CAP_WEAR
This routine is called either by the style program or by the tip dress check program for
pedestal tip dressing robots. For carried guns this routine should be called after the robot is clear of
transfer (Segment 63) and on the way home. For pedestal applications this routine should be called
before the drop off routine, so that the robot can update a gun while dropping the part off. This
routine calls NUM_GUNS which determines the number of servo guns on the robot. It then
increments a R15 by 1 and does a wear update on that gun. Once the number of guns limit is
reached it sets R15 to 0 and the updating starts back at gun 1. The Flag F1 allows this task to
competed prior to aborting the style program. See style templates for examples

TW_GUNS
This routine is called by TW_GNRST, after a cap change to run a tip wear update on all requested
configured servo guns. TW_UPDCC(X) is the tip wear program for new caps (Tip Wear Update
Caps Changed), where X is the gun number. This routine also makes sure that stroke is enabled, so
the robot does not try to update in no stroke.

Tip Reset
This routine gets called to reset steppers and tip wear. This can occur either at a 'Request
Continue' with a decision code 14, or as a style 27 'Cap Change'. For pneumatic gun applications this
routine checks that the watersavers have detected a 'Cap Loss' or are bypassed before allowing the
steppers to be reset. If it detects that the configured watersavers are not tripped, or bypassed it will
prompt the user to 1. Reset anyway or 2. Skip Reset. If the watersavers were tripped, or the operator
selected reset anyway, the robot will then reset the requested steppers and watersavers. Servo Gun
applications will alway reset all configured steppers and perform a TW_GUNS which will error proof
that the caps were changed and update the wear.

Recovery
The following are the recommended recovery procedures necessary to recover from the
most common and foreseeable errors that will occur once the servo guns are in production. It is
anticipated that this section will grow as we garner more information and additional lessons learned.
16.1 Recovery from Loss of Mastering
The steps outlined below are necessary to recover from a loss of mastering, after the robot
has been setup and programmed. It is recommended that the caps not be changed before the
following procedure, as the wear in the caps are accounted for in the recalibrate routine.
16.1.1
Mastering the Gun from the Master/Calibrate screen
This method is to be used to recover from a loss of mastering after initial setup of the servo
gun has been performed.
1. Do not replace the electrodes
The robot will use the existing cap wear to calculate correct position and update
the tip wear automatically
2. Press [MENUS] -> [NEXT PAGE] -> [SYSTEM] -> [Gun Master]
3. Select [Select F3:BZAL] to reset the battery zero alarm and cycle power
4.
5.
6.
7.
Re-Establish pulse with the encoder
Select [NEXT]
Jog the welding electrodes (tips) together until they just touch
Select [F4:RECALB]
This will master and calibrate the gun, and update the tip wear compensation
master position

-UNCONTROLLED WHEN PRINTED-
Global 3 Servogun Setup Users Manual for Fanuc SpotTool+ 8.20 with
GRS4 Customization
8. The axis is now mastered
9. Verify the weld path, and touch up if necessary
16.2 Cap configuration change
The steps outlined below are necessary to change from one cap configuration to another due
to product or process changes. This includes the change of cap size, say from a #2 short to a #2
long, or change from one shank style to another. It is not recommended to single axis master and
update limits on this axis, as this tends not to work, and can cause issues with tip wear.
16.2.1
Re-Run the wizard
To ensure that the transition from the original cap configuration to the new configuration is
successful and straight forward, it is necessary to delete the gun axis in question from the group, and
to re-enter the axis with the new information, paying close attention to the axis limits. The easiest
way to accomplish this is to re-run the wizard and to select YES when prompted to setup the servo
gun axis.
16.2.2
Mastering the Gun and Setting Axis Limits
Because the axis information has been updated it is necessary to re-run the gun mastering
and axis setup.
See section Mastering the Gun to re-master the gun
16.2.3
Running Tip Wear Setup
Because the mastering information has changed, particularly the master counts with the new
caps, it will be necessary to re-run tip wear setup.
See section Tip Wear Compensation to setup tip wear compensation. It may also be
necessary to update the wear ratio when changing cap configurations.

-UNCONTROLLED WHEN PRINTED-
Global 3 Servogun Setup Users Manual for Fanuc SpotTool+ 8.20 with
GRS4 Customization
16.2.4
Completing Pressure Calibration
Because the gun setup has changed pressure calibration has changed and should be
verified. Most likely the torque to force curve has not changed due to a simple cap change, but
should be verified. The values that were recorded during the initial setup of the pressure table are
still in the robot, and all that should be necessary is to select complete on pressure schedule setup.
There is no need to go and setup the pressure schedules again, only to verify the calibration.
See section Pressure calibration for information concerning pressure calibration.
16.2.5
Path Touch up
Because the tip configuration has been changed it will be necessary to touch up the path.
16.3 Motor Replacement
The steps necessary to recover from a motor replacement are nearly identical to those
outlined in Recovery from Loss of Mastering, with the added steps that Autotune needs to be run as
outlined in Autotuning, and pressure calibration needs to be re-run as outlined in Pressure calibration.
It should not be necessary to run Autotuning again
Steps to recover from motor replacement:
1.
2.
3.
4.
Replace Motor
Re-master the gun
Re-run Autotune for the specific gun
Re-Run Pressure Calibration
Note: This assumes that the replacement motor type is the same make and model.

SERVO GUN TOOL CHANGE OPTION
17.1 Purpose
The steps outlined in this section of the manual will help the user to add servo gun axis to the
robot for tool changing applications. The robot personality on the SpotTool+ 8.20 w/GRS4
Customization will have the option +SGChanger. This option on the personality will be used by the
user to add servo gun axis to group 2 or group 3 depending on configuration.
17.2 Hardware/Software Requirements, Limitations and Recommendations
For a robot that has tool changing for carried servo weld guns enabled, the robot is
configured for a single weld gun, one weld controller and one water saver. To be able to tool change
multiple carried servo weld guns, you will need the following on the robot controller:
1. Robot controller hardware (Fanuc part # A05B-2507-C400) to support this option. Specify
this part with “kit” in syntax when ordering to receive all the parts like connectors etc.
2. All Tool changing robots will need to be upgraded to Spottool v8.20Pxx.
3. J665 Fanuc Servo Gun Change software option loaded on the robot
4. Battery packs for the Tol-O-Matic motor (1 pack per gun Tol-O-Matic part # 27509039). The
battery packs are to be purchased from Tol-O-Matic, by the gun supplier or by the line
builder.
5. Maximum of 4 servo weld guns on tool changers are currently supported by GM.
6. Guns cannot be shared between robots. For example, Robot R1’s guns cannot
be used on Robot R3 and vice versa.
7. Guns will be dropped off in their respective nests with tips opened.
8. We recommend that you teach the pick and drop paths for the weld guns in TOOL # 5 or a
tool number that is not being used. If maximum number of guns is 2, you could teach these
paths in tool number 3.
9. To avoid confusion, reserve TOOL # 1- Tool # 4 for weld gun Utool’s since by default the gun
attach routine will set the utool to the gun # it is picking and the gun equalization is based on
the utool information which will also normally default to gun number.
10. Set the dip switches representing gun number on the tool side (Node 55) of the tool
changers, prior to commencing programming.
11. Air guns and servo guns cannot be mixed on the same robot.
12. Carried weld guns and ped weld guns cannot be combined on robots with gun tool changers
13. Gen. 6 weld timer is required for multi gun tool changing
14. An Ethernet cell interface is required and the expanded I/O map required. Custom mapping
will be required on Global 1 robots.
15. Air guns use integrated dense packs, shoulder mounted valves and/or hip mounts are not
supported.
16. Whenever any gun requests / requires cap change, all caps will be changed on all guns
17. Tip dress before cap change is only required on the gun that is held at the time of cap
change, not all 4 guns. The tip dresser only needs to run once to verify cutter functionality.
18. If multiple tip dressers are required to accommodate different cap / cutter combinations,
additional steps will be required to dress before cap change.
19. One gun is held during cap change process.
20. Water saver can only verify the caps are changed on the gun that is held. Cannot error proof
that caps have been removed from all guns.

All guns are dressed after cap change before next job is processed.
All guns are stored in the, at home, open position when on the stands.
Cap change must be planned activity with time allotted for it.
Tip dressing occurs after the current job is processed and before the next job starts. If two
guns are used on a single job and one needs to tip dress, gun that requires it is picked up
and dressed at the end of the job before next job is started.
If multiple tip dressers are required to accommodate different cap / cutter combinations,
additional steps will be required to dress before cap change.
All guns are stored in the, at home, open position when on the stands.
Water saver can only verify the caps are changed on the gun that is held. Cannot error proof
that caps have been removed from all guns.
If the PLC or Robot or WC losses memory or is reloaded, all caps must be changed and all
guns are dressed before next job. Manual intervention required
The robot and the PLC must track which gun is held.
FFR does not swap guns; FFR only applies to the gun that is held. FFR does not support tool
change for hot backup.
Robots will be processed to hold the high runner tool at home under normal conditions. After
cap change or tip dress the robot may have to pick up the high runner tool on the next cycle.
17.3 Hardware Setup Procedure for Carried Servo Weld Gun(s)
The procedure described here is strictly for carried servo guns on tool changers for changing
2 guns. If adding more than 2 guns, this procedure has to be repeated for guns 3 and 4. It is
recommended to discuss special cases with VS Robot Software Standards Team since every
possible combination cannot be comprehended in this manual.
1. Run the Setup Wizard for GUN #1 as described in Section 3. Run the wizard as a single
carried gun. In servo gun tool changing applications all the guns that are on tool changers
belong to the same group but with multiple axis. Typically in strict carried servo gun tool
change application, the servo guns will belong to group 2 with 2 axis, one for each gun.
2. Control Start the robot again.
3. Press [MENUS, MAINTENANCE], then press [ENTER]. The screen will indicate GROUP 1
the robot arm and GROUP 2 servo axis. GROUP 2 will require modification; this GROUP
can contain up to 3 more servo axis for a total of 4 servo guns.

4. Cursor down to Servo Gun Axis and Press F4 [MANUAL].
5. Servo gun axis for servo guns on tool changers are added to the servo gun changing group.
In this case of 2 carried guns on tool changers, axis will be added to group 2. By running the
wizard, we have already added axis 1 to group 2 and now we need to add an additional axis
to this group.
Total Servo Gun Axes:
This value will be equal to total
number of guns. Each time an
axis is added this value will
increment.
6. Press [#2 Add Servo Gun Axis].

13. Press [Function, Cold Start].
17.4 Running SRVO_TC.PC
To assist with set up of Servo Gun Tool Change for the Additional AXES added the PC file
SRVO_TC.PC has been created. This setup file must be run outside of the customization wizard
after the hardware was configured in Section 15.3. Run the file SRVO_TC.PC at a normal Start and it
will load the GM Standard Pressure Calibration data setup, Pressure table setup, Distance schedule
setup, additional nest I/O.
17.4.1
SRVO_TC.PC File Execution Procedure
1. Press [Select], and select the program SRVO_TC.PC from the listing.
2. Press [ENTER] on the program and ENABLE the teach pendant and hit [SHIFT FWD] to run
the program.
3. User will be prompted for total number of guns, and total number of tipdressers. Answer all
questions then cycle power on robot controller or use the teach pendant to cycle power.
17.5 Programming and Setup Completion
The gun setup and pressure calibration now needs to be completed for each gun. The pick
and drop paths must be taught and GUN ATTACH macro executed prior to finishing setup. Refer to
Section 18 of this manual for path file naming conventions. We recommend that you program the
pick and drop paths with a UTOOL number greater than the maximum number of guns. That is if we
are tool changing 2 weld guns, then program the pick path and drop paths with UTOOL number
greater than or equal to 3. Since servo gun robots uses UTOOL orientation to determine its
equalization direction and the UTOOL is set via the GUN ATTACH macro, UTOOL 1 for gun 1 and
UTOOL 2 should be used for gun 2. When performing auto tune etc., if the robot is not holding a gun,
you will see the following screen.

17.5.1
GUN ATTACH[x]
This macro with the argument value is used to let the system know the gun number the robot
is picking up. It should preferably be called after the gun is latched to the robot side of the changer
and it attaches servo gun to the robot without the need for cycling power.
Example: GUN ATTACH [1] or GUN ATTACH [R[X]] or GUN ATTACH [AR[1]]. After servo gun is
attached, the UTOOL number is changed to the argument number (hence the need to have utool
number match the gun number) which is specified as a gun close direction of fixed side in the servo
gun setup screen.

17.5.2
GUN DETACH[x]
This macro is used to detach a servo gun without powering off. By default, the calibration
motion type is set to “Type 7”. This can be changed on the servo gun setup page by changing the
Battery to “OFF”. By setting the calibration motion type to “Type 7” prior to detaching the servo gun,
the servo gun is closed automatically, and the gun close position is set as the reference position.
Refer to E-Doc for further clarification on other calibration types. MAAC direction is to use batteries
on servo guns, so other types of calibration types should not be use.
Example: GUN DETACH [1] or GUN DETACH [R[X]] or GUN DETACH [AR[1]]
GUN ATTACH AND GUN DETACH WILL NOT execute by backward execution (SHFT BWD).
17.5.3
Emergency Detach (EMGDTCH.TP)
This macro is used to disable the communications to servo gun axes when there is damage
to the communication of the servo gun. This macro can be executed ONLY in teach mode, followed
by a power cycle from the teach pendant to reset all servo gun attach[x] variables. After execution of
this macro the user can now manually decouple the gun and fix the communications issues with the
servo gun.
17.5.4
Verification of Gun(s) connections
Once a gun is picked up and the GUN ATTACH macro has been executed, verify that the
attached gun is correct by visiting the Gun Change Status screen.

This routine is used to perform attached gun verification and gun swap with the required gun.
If the attached gun on the robot is not the one that the passed argument calls for, the robot will
perform a gun change with the correct gun (passed argument). You may choose to modify the path
calls, if the path naming for pick and drop is different than the one used in here. For example; if the
path name in your particular application is “S10PICK1”, than change TCPICKH1 to “S10PICK1” etc.

Troubleshooting Servo Gun Tool Change
19.1 The attach instruction is executed when the gun is not attached
Phenomenon: The gun is not actually attached. So, a communications alarm such as
"SRVO-068 DTERR alarm" occurs on the pulse coder. Correct this by Remedy 1 or Remedy
2 below according to the present conditions.
Remedy 1 :
Turn the machine lock ON in the servo gun operation group (normally, group 2) in the Test
Cycle screen.
Move the robot by manual feed so that the robot and gun are physically attached.
1. Turn the controller OFF then ON again.
2. The gun pulse values and mastering data are lost. So, first move the gun by
manual feed to cancel the "SRVO-075 Pulse not established" alarm.
3. Then, carry out gun 0 position mastering and calibration manually.
4. The gun pulse values and mastering data are lost. So, move the gun by manual
feed to cancel the "SRVO-075 Pulse not established" alarm.
5. Carry out gun 0 position mastering and calibration manually. The gun 0 position
may be an approximate position.
6. Execute the detach instruction to temporarily detach the gun. Also, physically
detach the gun from the robot. Otherwise, the gun will not be calibrated at the
next attach operation.
7. Execute the attach instruction again to attach the gun. Calibration this time is
carried out at the reference position to restore the position.
8. Battery mounted gun. The gun is attached and positioned, so it can be used as
it is.
Remedy 2 :
1. Directly change the system variable to detach the gun. To do this, set the following
system variable to "0":
$SCR_GRP[servo gun operation group No. (normally, 2)].$AXISORDER[all 1 to 9] = 0
2. Turn the controller power OFF then back ON.
3. The robot starts up with the gun in a detached state. Move the robot by manual feed to
physically attach the robot and gun.
4. Execute the attach instruction to attach the gun.
5. The gun can be used as it is after it is attached regardless of the battery type.

19.2 A different gun from that specified by the attach instruction is attached
Phenomenon
The gun is attached to the robot, but the gun’s current position is the wrong value.
Remedy
The following describes an example where gun 2 (actually attached gun) is attached to gun 1
(gun No. taught by the attach instruction).
1. In this state, the gun cannot be detached from the robot by the detach instruction.
So, directly change the system variable to detach the gun. To do this, set the
following system variable to "0":
$SCR_GRP[servo gun operation group No. (normally, 2)].$AXISORDER[all 1 to 9] =
0
2. Turn the controller power OFF then back ON.
3. The gun starts up in a detached state.
4. Execute the attach gun[2] instruction to attach gun 2. (In this state, gun 2 should
be physically connected to the robot.)
When gun 2 is a battery-less gun and the calibration motion type is 1 or 2:
If gun 2 is moved when attached by mistake instead of gun 1, gun 2 will move and be
at a position different to when it was detached. So, gun 2 may be calibrated to the
wrong position by the attach instruction executed in step 4 above, resulting is
misalignment between its actual and desired positions. In this case, carry out gun 0
position mastering and calibration manually.
When gun 2 is other than the above:
Gun 2 can be used as it is.
5. Gun 1 can be used as it is by executing the attach instruction to attach the gun.
19.3 The attached gun has been detached by mistake (without using the detach instruction)
Phenomenon
The gun is not actually attached. So, a communications alarm such as "SRVO-068
DTERR alarm" occurs on the pulse coder. Correct this by Remedy 1 or Remedy 2 below
according to the present conditions.
Remedy 1
Same as Remedy 1 of C-1
Remedy 2
Same as Remedy 2 of C-1

19.4 The battery voltage has fallen
Phenomenon
The "SRVO-065 BLAL" alarm has occurred with the gun in an attached state.
Remedy
1. Change the battery with the gun attached.
2. The gun can be used as it is.
19.5 The battery ran low while the gun was detached
Phenomenon
The "SRVO-062 BZAL" and "SRVO-075 Pulse not established" alarms occurred when
the gun was attached.
Remedy
When the reference position has not been set:
1. Press F3:RESET_PULSE in the Calibration screen, and select YES.
2. Turn the controller OFF then ON again.
3. Move the gun by manual feed to cancel the "SRVO-075 Pulse not established"
alarm.
4. Carry out gun 0 position mastering and calibration manually.
When the reference position has been set:
5. Press F3:RESET_PULSE in the Calibration screen, and select YES.
6. Turn the controller OFF then ON again.
7. Move the gun by manual feed to cancel the "SRVO-075 Pulse not established"
alarm.
8. Move the gun by manual feed to the reference position marked by a line marking
or alignment mark.
9. Execute 3 QUICK MASTERING in the Calibration screen.

20.2 Common Errors on Servo Gun Errors
20.2.1
SRVO-023: SERVO Stop error excess (G:%d A:%d)
Cause: When the servo stopped, the position error was abnormally large.
Remedy:
1. Check the ARM1 cable for connectivity, and that no bent pins exist.
2. Check voltage on ARM1 cable (approx100-300Vac when commanded to move).
3. Check that gear ratio is set correctly and matches gun tag. Press Menu’s then Type
select Autotune the value will under Tip Displacement.
4. If a disconnection is not found, replace the servo amplifier or the servo motor.
Cause: Robot encounter SERVO Move error excess during the pressurization of a weld.
This could indicate that the robot would have to exceed the gun close limit to achieve
the desired pressure.
Remedy: Increase the gun closed limit in small increments. Standard limit is 20mm do not
increase beyond 25mm. (Contact Lead Robotics Engineer if problem persists)
*BEWARE: GUN DAMAGE CAN OCCUR BY BLINDLY INCREASING THIS LIMIT*
20.2.2
SRVO-024: SERVO Move error excess (G:%d A:%d)
Remedy: Take the same action as for SRVO–023
20.2.3
SRVO-069: SERVO CRCERR alarm (Grp:%d Ax:%d)
Cause: The serial data has been disturbed during communication.
Remedy:
1. Check for loose connection on the ARP1 cable. Then reboot robot.
2. Check cable routing (isolate cable from 480v cables and RM1 robot cable) to reduce
interference.
3. Check for water intrusion in ARP1 connector at servo motor and inside servo gun end
cap. Common for vertical mounted ped guns where bushing is facing upward.
4. Replace servo gun motor.
20.2.4
SRVO-062: SERVO BZAL alarm (Group:%d Axis:%d)
Cause: This alarm is issued when the battery for backing up the absolute position data of the
pulse coder is not connected. The battery cable inside the robot might have become
disconnected.
Remedy: Correct the cause of the alarm, by pressing MENU’S then SYSTEM select GUN
MASTER press F3 and reboot robot. Mastering will need to be performed at this
point.
20.2.5
SRVO-068: SERVO DTERR alarm (Grp:%d Ax:%d)
Cause: The serial pulse coder did not return serial data in response to a request signal.
Remedy:
1. Make sure that the ARP1 connector on the servo gun is securely connected and check
for bent pins.
2. Check that the shielding of the robot interconnection cable (for the pulse coder) and
check that cable is not run with 480v cables.
3. Replace the robot ARP1 cable (for the pulse coder).
4. Replace the pulse coder.

20.2.6
SVGN-023: Incomplete Pressure calibration
Cause: Incomplete pressure calibration.
Remedy:
1. Go to the Servo Gun Setup: General Setup Page.
2. Select Pressure Cal. and complete the Pressure Calibration process.
20.2.7
SVGN-024: Incomplete Wear Down calibration
Cause: Incomplete Wear Down calibration.
Remedy:
1. Change Caps with New Caps.
2. Check Zero Position of the Servo Gun and Master if necessary.
3. Run TW_SETG1
20.2.8
SVGN-032: Tip increased error
Cause: The tip wear down value exceeds the increased error.
Remedy:
1. Check to ensure the CORRECT Weld Tips are on the Weld Gun.
2. If the Weld Tips are not correct, change them, and run Cap_chng/Reset Steppers.
3. If the Weld Tips are correct, run Capwear and verify the gun is closing completely during
the Capwear routine.
4. If the Servo Gun Does not close completely while running Capwear, apply lubricant to the
shaft, exercise the Servo Gun and retry Step 3.
5. If the Servo Gun still does not close the gun may need to be recalibrated (Auto
Tuned/Pressure Cal). Pay close attention to the Gun Impedance Value before and after
Auto Tuning. If the Gun Impedance Value increased significantly, the Servo Gun may
have a bind or the Servo Motor may need to be replaced.
6. If a bind is suspected on a C-Type Weld Gun, check the Guide Rod (Slide on Global) on
the Movable Side for straightness, wear and heat. Repair/Replace Guide Rod and re-run
Step 5.
7. If the Servo Motor seems excessively noisy or the shaft of the motor is excessively
warm/hot, remove the Servo Motor. If the Servo Motor is Noisy, replace the Motor.
Inspect the Bushing (Slide on Global) for weld debris, which may cause the increased
Gun Impedance.
20.2.9
SVGN-118: Max wear exceeded
Cause: The maximum tip wear amount has been exceeded.
Remedy:
1. Inspect weld tips for excessive heat and abnormal wear, and inspect weld gun arms for
cracks.
2. If Weld Tips appear normal replace and run Cap_Chng/reset steppers.
3. If there appears to be excessive heat on the weld tips, check for adequate water flow and
check the water tube inside the weld shank.
4. If there appears to be abnormal wear, check the tip dress path, weld pressure at tip
dress, and the tip dress cutter.
5. If weld gun arm is cracked, replace gun arm, check servo gun mastering, and verify all
process/tipdress paths.

20.2.10
SVGN-020: Pressure shortage
Cause: Actual pressure is less than the requested pressure.
Remedy:
1. Check mastering of tips.
2. Check tip wear if questionable install new caps and run TW_SETG1 (Always verify stoke
limits before using TW_SETG(X).
3. If problem still exist check part thickness and pushing depth settings in the pressure
schedule.
4. If this fault only occurs during CAPWEAR then the gun impedance has changed therefore
auto tuning and pressure calibration are required. The gun needs to be inspected to find
the cause of the impedance change, common issues are weld slag buildup in bushing,
improperly installed bushing, and bent guide rod, (c-gun slide in global applications) If
any of the above issues are present-correct the issue and perform auto-tune and
pressure calibration before resuming use of the gun.
5. Record all values associated with Standard Over Torque (Section 7).
Note: . Autotune and Pressure calibration is required if any gun mechanical parts are
modified or re-worked.
Always verify the Standard Over Torque (Section 7) before after any mechanical
maintenance is performed on the servo gun to see how it affected the characteristics
of the gun. Compare old Standard Over Torque values with the new parameters from a
re-worked gun
20.3 How to check gun impedance:
1. Press Menus key
2. Select Setup then hit ENTER
3. Press Type[F1]
4. Select Servo gun
5. Cursor down to 2nd line (General Setup) then hit ENTER
6. Cursor down to Overtorque Protection then hit ENTER
7. Press OK
8. Select Parameter Summary then ENTER
9. Verify item 1 (Display Units) is in TorqCt if not Select F4 to change
10. Gun Impedance is displayed in the row stating “Std. Overtorque Value”.

20.4 Servo Gun Amp Settings with Gun(s) & Hardware Mismatches
When a controller is equipped with additional amp channels than the amount being used by
the application, the additional amp channels have to be mapped to eliminate hardware
mismatches. For example, if a robot controller has a single amp as amp 1 and dual amp as
amp 2 but is only configured for 1 gun on each amp, the additional amp channel must be
configured by setting the following system variables:
$SCR.$ATR[9]=9
$SCR.$ATRATTRIB[9]=0
