INTRODUCTION
Thank you for purchasing the SUMITOMO highperformance AF-3100α. The AF3100α provides highprecision speed control from ultra-low to high speed in
sensorless vector mode. The AF3100α can provide
control to +/-0.2% with a speed range of 120:1
(maximum @ 60Hz). Speed control as precise as a DC
motor control is possible in sensorless vector
operation.
An important feature in the complete control of the
AF3100α is allowed in three separate modes:
Sensorless Vector, Volts/Hertz and Vector Control
(closed loop using Pulse Generator Feedback)
In addition, high torque at low speed with sensorless
vector control selected allows for a maximum of 200%
torque and can be obtained over the 120:1 speed
range. This is comparable to DC control. The starting
torque capacity is a maximum of 250%.
Please read and observe all safety instructions.
Do not make withstand voltage tests on any part of the
AF-3100α AC drive. The AF-3100α uses
semiconductors that are vulnerable to the high voltages
used by withstand testing equipment.
During installation, be sure all terminals are tightened
to the recommended torque rating. Refer to the
instructions detailing torque values.
Handle with care to avoid damage to the AC drive. Do
not pick up the inverter by the covers; use the heat sink
when lifting and transporting the unit.
Please keep this manual available for maintenance and
inspection procedures. For guidelines on maintenance
and inspection, refer to the “Inspection of Generalpurpose Inverters” prepared by the Japan Electrical
Manufacturers’ Association.
High-performance auto tuning is available in this stateof-the-art drive. Just select the auto-tuning function and
the motor data are automatically read with the motor
operating under optimal conditions. The AF3100α
Series allows the user to more easily adjust the
performance of the drive with the motor.

Use shielded wire or twisted shielded wire for wiring to
the control circuit. Do not run control wiring in the same
conduit or wire-way with input or output power wires.
Pay special attention to the distance from the motor to
the inverter. The longer the wiring run, the higher the
voltage drop. Wiring lengths greater than 30m/100ft will
affect the performance of the inverter. Installation of an
AC line reactor may be necessary.
Important Note: Configure jumpers S, TX1, TX2 &
TX3 for proper short circuit protection. See Note 2 on
the AF-3100α connection diagram for settings.
The grounding wire must be sized according to the
National Electric Code or local electrical codes in effect
at the point of installation.
Design precautions
Input signals to the AF-3100α are low voltage, low
current control signals requiring relay contacts rated for
low energy, micro-control signal operation. Use goldflashed, silver-plated or other low-resistance contacts.
If the start signal input is ON (closed) when a power
failure occurs, the inverter will automatically restart
when power is reapplied. Fail safe methods include
three wire control to the inverter control terminals or
installation of a electromagnetic contactor on the
inverters input side configured to drop off-line during
power failure to prevent unintended starts.
As shown in the table below, decrease the carrier
frequency using parameter C13 to prevent the adverse
effects from long cable distances. Do not run multiple
sets of drive to motor conductors in a common wire
way or conduit. This practice may result in inductive
coupling of voltage between different sets of motor
leads, which can cause equipment damage, and a
safety hazard may exist.
Power
supply
Do not apply voltage to the input points (FR, RR, etc.)
of the control circuits. These are active low inputs and
are not intended for voltage inputs.
Possible short circuit
Inverter
Fig. 4-1
Form C relay contacts FA and FB are intended to
operate in series with a relay or other electrical device.
To prevent failure of these contacts do not exceed the
current or voltage ratings.
Use of a power transfer switch during inverter
operation may result in a catastrophic failure of the
drive due to a momentary shorting of the contactors.
To prevent this possibility, use electrical or mechanical
inter-locks for MC1 and MC2. Please refer to
Figure 4-1.

Proper wiring practice requires power wiring (AC input
power or inverter output) to be kept separate from
control circuit wiring. Maintain a minimum separation of
36 in/1m between parallel conduits. If it is necessary
for power and control wiring to cross, cross at a 90°
angle. Do not place input feeder cables in the same
conduit as the motor leads.

NOTE: When initially operating a 3-phase AC motor, the direction of rotation is undetermined. If the drive
machinery can be damaged by rotation in the wrong direction, uncouple the motor from the load before
attempting to operate the drive.

The AF-3100α requires separate grounding.
When more than one AF-3100α is used, ground them
as shown in Figures 1 or 2 shown below.
The grounding cable in a 3 phase/4 wire system should
be used as the grounding conductor between the
motor and the drive. Ground the motor to the cable
ground and wire the cable ground to terminal E on the
inverter. For long cable runs contact the factory for
assistance. Refer to NEC and local electric codes for
additional wiring guidelines.
Use grounding method (1) for the preferred ground
method. If method (1) is not possible, use grounding
method (2). Grounding method (3) is not
recommended.
Note: Do not apply external power to these terminals.

Inverter chassis grounding terminal.
Supply voltage selection terminals. Only on 460 V class units of 15 kW or above.
For inverter supplied control power, connect r-r1 and s-s1, respectively. For externally
supplied control power remove the r-r1 and s-s1 jumpers; input 230 VAC power to r1 and s1.
(Input 230 VAC to both 230 and 460 V units). The external control circuit terminal block (see
note) is on the driver card.
Power supply for the external speed (frequency) potentiometer (variable resistor: 1-5kΩ).
10 VDC; maximum supplied current 10 mA.
When 0-5, 0-8, or 0-10 VDC is input, the output frequency reaches its maximum at 5 V, 8 V
and 10 V, respectively. Select paramater A 00/12 for 0-5, 8, or 10 V operation.
4-20 mA (DC), the output frequency reaches its maximum at 20 mA, minimum at 4mA.
Input resistance: 250Ω.
Common terminal for frequency adjustment signals (terminals: +V, VRF, and IRF).
FR-BC contact closed results in forward rotation; deceleration/stop when the contact is
open.
RR-BC contact closed results in reverse rotation; deceleration/stop when the terminals
are open.
When the contact terminals ES-BC are closed, the inverter faults and an alarm signal is
latched and output to FA and FB. To re-start the inverter a reset must be initiated by closing
RST-BC. External relays can be used to fault the inverter by closing ES-BC, the fault can be
software selected to External Fault (NO) or External Fault (NC). The factory default External
Fault (NO).
When the contact terminals MBS-BC are closed, a coast stop is initiated. Operation
begins from 0 Hz when the MBS-BC is re-opened and the signal FR or RR is closed. When the
digital input is set for catch on the fly start, operation from coast stop is allowed. No alarm
signals are output.
The following functions can be selected: Preset speed selection, JOG selection, 2nd
deceleration selection, B mode selection, local/remote operation command, frequency
command selection, hold selection, frequency increase, frequency decrease, and catch on the
fly function.
When the terminals RST-BC are closed, the inverter is reset to allow for normal operation.
Common for digital input signals.
Depending on the selection (see parameter E02), a 0 to 1 mA DC current is output on terminals
FRQ+ and FRQ-in proportion to the output frequency of the inverter. Digital pulses with the same
frequency as the output frequency of the inverter can also be selected for output. Factory default
setting is a pulse output frequency at 1 mA for 60 Hz. The input impedance of the meter shall be
less than 500Ω.

OPERATION
5-1. Safety precautions
DANGER
Do not operate unless in a dry environment.
Do not touch any component of the inverter with power applied. Some components are at DC bus
potential after input power is removed for several seconds.
If the inverter has a run signal, the inverter will restart upon RESET. Always open run contacts before
reseting inverter.
Always install the front cover before applying AC power. Do not remove the cover with power applied.
Provide a separate, independent emergency stop contact for the inverter.
Verify the driven load can be safely operated; if not, ensure the motor is uncoupled from the
connected load.
Note: When initially operating a 3-phase AC motor, the direction of rotation is undetermined. If the driven machinery can be damaged by rotation in
the wrong direction, uncouple the motor from the load before attempting to operate the drive.
CAUTION
Do not touch the heatsink or braking resistor; temperatures in excess of 300° C can be present.
Verify the speed ranges of the inverter match the allowable speeds of the connected motor.
Use an external motor brake as necessary.
Do not touch the cooling fan.
26
5-2. Operation Checklist
5-3. Sensorless Vector Operation
When installation and wiring are completed, verify the
following checklist before applying power:
• Are the AC input power connections (R, S, and T)
and motor connections (U, V, and W) wired
correctly?
• Are the jumper settings for the control power supply
correct (r1,r,s1,s)? If an external power supply is
used, are the jumpers removed and input
connections to r1 and s1 correct?
• Are the output terminals (U, V, and W) connected in
the correct phase order? Verify motor rotation before
operating inverter.
• Verify no short circuit exists in the motor cable.
• Are wire connectors securely tightened? Is all
mounting hardware (such as screws) securely
tightened?
• Is the wiring and logic of the external control devices
verified and tested for proper operation?
• Has the operation of the motor and load been
verified for safe operation?
• Is the AC input supply voltage and voltage rating of
the inverter confirmed? (400 V class unit: Are the
supply voltage jumpers properly configured? (Refer
to S, TX1, TX2 and TX3)
Applying power
Apply power with the inverter in the OFF position and
confirm there are no faults. Should a fault exist,
immediately remove the power and check the wiring of
the inverter. If there is no fault, the “READY” lamp
(green) on the OPU/keypad will illuminate. The inverter
is ready to run.
Trial operation
Verify that the driven load can be safely operated or, if
not, that the motor is uncoupled from the connected
load. Note: When initially operating a 3-phase AC
motor, the direction of rotation is undetermined. If the
driven machinery can be damaged by rotation in the
wrong direction, uncouple the motor from the load
before attempting to operate the drive.
The operation unit (OPU/keypad) permits selection of
local or remote operation modes. Respective operation
modes are explained below; however, only the OPU
mode numbers are shown here. For programming the
inverter by using the OPU, refer to “ Section 6. How to
use the operation unit.”
Unless the necessary parameters are set correctly, the
sensorless vector operation may not perform as
expected.
• Set the following motor parameters as shown below:
(Refer to parameter table Menu C)
• Menu C09: “Number of motor poles”
• Menu C10: “Type of motor”
• Menu C11: “Motor capacity”
• Menu C12: “Control method selection” to 1:
Sensorless
• Menu settings for motor cable selection.
• If the motor cable exceeds 10 m (33 ft.) the
resistance of the cable increases; motor terminal
voltage is reduced resulting in less developed torque
in the motor. To prevent these losses, configure the
motor wiring parameters as follows:
Motor cable distance (Menu Parameters C14 and C15)
• if the motor cable is less than 10m/33 ft - no
parameter changes are necessary
• if the motor cable equals 10m/33 ft - parameter C14
is ignored
• if motor cable greater than 10m/33 ft - configure C14
“cable size” and C15 “cable distance”
• Proper sizing of motor cables should be selected in
accordance with the National Electric Code (NEC)
and/or local electrical codes. Typically size the cable
for a calculated voltage drop of less than 2% of the
rated output voltage. Refer to the NEC or local
electrical codes for sizing guidelines.
• Setting the carrier frequency.
• For long cable runs refer to the chart shown in
Section 4-3. Improper setting of the carrier frequency
will affect the inverters performance with possible
adverse effects from harmonics, reflected waves and
voltage drops. The carrier frequency must be
carefully selected as shown on page 14.
* If the carrier frequency is improperly set for long
cable runs, sensorless vector operation may not
produce expected performance.
* Sensorless operation permits operation of one motor
with one inverter. In this mode, two or more motors
cannot be operated by one inverter. When operation
of more than one motor is desired, configure C11 to
0: V/Hz to select Volts/Hertz operation.
Line voltage drop = 3x Line resistance (mΩ/3) x Wiring distance (m) x Current (A) (V)

Local operation (Operation with OPU/keypad)
The use of the OPU/keypad, in local mode, is recommended during installation. This will assist in
configuring and testing of the inverter. The inverter is factory preset for local operation from the OPU.

Not provided: 0
The built-in dynamic braking transistor-resistor

prevention is deactivated. If an external braking unit is
connected, paramter C03 must be set to “0”.
Provided: 1
The overvoltage stall prevention is active with
parameter C03 set to “1”. This prevents operation of
the built-in dynamic breaking transistor.
C04: Regenerative braking rate
The AF3100α provides a built-in transistor for
regenerative braking in the 5.5-15 kW range for the 200
V class and 5.5-15 kW range for the 400 V class. A
braking resistor can be connected externally, if
necessary.
C04:
This parameter is used to prevent over heating of the
dynamic breaking resistor by setting the effective duty
cycle. This value should be less than the rated effective
duty cycle of the braking resistor. If this parameter
value is exceeded, the internal braking transistor is
deactivated. For a duty cycle rate greater than 30% or
if an over-voltage condition exists, use an external
braking unit to prevent damage to the inverter. This
setting does not apply when the inverter is not
equipped with an internal braking transistor or if a
braking unit is used.

Electronic thermal relay
C08: Motor rated current (electronic thermal relay)
The rated current of the inverter is factory preset. An
overload fault occurs if the current is 150% of the
preset current for one minute. This overloaded
condition can be monitored by the electronic thermal
relay load factor set by M03. When a general-purpose
motor is selected by parameter C10, the current is
decreased according to the heat characteristics of the
general-purpose motor. If the output current exceeds
150% of the rated current of the inverter, the electronic
thermal relay operates according to the i 2t
characteristic; if the current exceeds 180% of the rated
current, an overload fault occurs in 0.5 second.
If the cable length exceeds 10 m / 33 ft, configure
C14 and C15 or perform an auto-tune to ensure
satisfactory performance. Since slip compensation
is performed during operation in sensorless control
mode, the preset frequency will be different from the
output frequency. When the B mode is selected by
the digital input terminal, the V/Hz control in the B
mode is selected instead of sensorless control.
Carrier frequency
C13: Carrier frequency
C09: Number of motor poles
The PWM (pulse width modulation) carrier frequency is
configurable. If there is a long distance between the
inverter and motor, decrease the carrier frequency to
prevent undesirable harmonic effects such as leakage
currents and coupling to other circuits. However, lower
carrier frequencies increase motor noise but reduce
harmonics.

Energy-saving control selection
C17: Energy-saving control
When this parameter is set to 1: “Provided,” energysaving control is active. This control is effective for fan
and pump applications. Satisfactory energy-savings
cannot be expected for machines that are accelerating
and decelerating frequently or for those with heavy
loads applied; this parameter will not correctly function
under these conditions.
Droop control
C18: Droop control gain
Configure the droop rate of the output frequency with
respect to the base frequency during constant torque
operation of a motor. Droop control will decrease the
frequency according to the load. This function is
effective for coordination of multiple motors in a
process line.
Droop gain = (Droop frequency/Base
frequency) * 100 (%)
For automatic boosting and sensorless control, an
electric constant is needed for the motor. The autotuning function automatically measures this constant of
the motor.

Set parameters C20-C23 to the rated values as
shown on the motor nameplate. Begin an auto-tune
using parameter C24. The system begins the autotune mode and the READY lamp on the OPU blinks.
Press the FWD or REV key on the OPU, and the autotune begins. If the auto-tune is completed with
incorrect parameter settings, reset parameters C09C11 to the factory preset values.

the B mode deceleration time necessary for the
frequency to decrease from the acceleration/

the 2nd acceleration/deceleration time is given priority.
CAUTION
During an auto-tune, exercise proper care if the
motor is connected to a machine. Parameter C24
allows for auto-tuning with motor rotation or without
motor rotation. If necessary de-couple the motor
shaft if damage to the machine may occur; otherwise,
if coupled, ensure the motor shaft will not rotate

CAUTION
When the instantaneous stop/start is set to
“Provided: 1” or the number of retry attempts is set to
any value other than 0, the system will suddenly
restart when the fault is removed. The machine
should always be designed to ensure operational
safety.
Parameter E13, Instantaneous stop/start selection,
permits an automatic restart if the parameter value is
set to “1” and is inactive if the parameter value is set to
“0”. This parameter will allow automatic restarts after a
temporary under-voltage condition for the input voltage
supply. There are no limits to the number of restarts
due to this condition.
When E13 is set to “1”, a temporary under-voltage
condition is not regarded as a fault and the fault relay
contacts FA (N.O.) and FB (N.C.) are not affected.
Faults subject to the retry attempts set by E14 and E15
are over-voltage and over-current.
If the number of retry attempts are exceeded, an error
is generated and the inverter faults; however, faults are
not output during restarts and retry attempts due to
instantaneous under-voltage and over-current.
Parameter E15, retry wait time, will affect the inverter
after an instantaneous fault. Parameter E15, retry wait
time, should be set to allow the conditions that caused
the fault to be cleared. If this time is set too short,
over-current, overload, or other faults may occur;

TROUBLESHOOTING/MAINTENANCE
AND INSPECTION
DANGER
Only qualified persons should attempt to inspect or repair the inverter.
Do not alter, attempt repair or replace unauthorized parts in the inverter.
Delay inspection of the inverter until approximately 10 minutes has passed. Potentially lethal voltages
exist in the drive and may remain at dangerous levels for several minutes after the power is removed.
Before attempting to service this controller, wait until the “bus charged” lamp goes out and measure
the DC bus voltage to insure that it is zero. Check the DC voltage between P and N and confirm that it
is less than 45 V.

During constantcauses include a high impact load during acceleration/decelspeed operation
eration or an overload condition during constant-speed
During deceleration
operation. Fault results in a coast stop.
A fault occurs when the inverter DC bus voltage exceeds approximately 395
volts for the 200 volt class and 790 volts for the 400 volt class. Regenerative
energy during deceleration of the motor charges the DC bus above limits
causing a fault alarm. A surge in the power supply system may also cause
this fault. A fault results in a coast stop.
The electronic thermal relay of the inverter detects an overload
by means of the output current. If the current exceeds 100%
of the rated current but less than 200%, the protective circuit
operates according to the thermal protection characteristics of
the inverter. A fault will occur resulting in a coast stop. Note:
Multi-motor connections require individual thermal relays for
each motor. (Overload rating: 150% @ 60 seconds, 200% @
0.5 second)
A fault occurs if a power failure to the inverters AC input
voltage is longer than 15 milliseconds; or the DC link voltage
drops –20% (approximately 200 volts or less) for the 200 Volt
class inverter or –15% (approximately 400 volts or less) for
the 400 Volt class. The fault results in a coast stop.
A fault occurs if any phase is grounded (shorted to ground) or
if a current is detected in the ground circuit. The fault results
in a coast stop.
A fault occurs if any phase is short circuited (phase to phase,
phase to ground). The fault results in a coast stop.
This fault indicates the internal drive heatsink temperature
has been exceeded. The fault results in an alarm.
Closing the control terminals ES-BC causes an external fault
resulting in a coast stop. The input can be selected as a N.O.
(normally open) or N.C. (normally closed) contact using
parameter F00. A system reset is required to return the
inverter to normal run status.
Number of retry attempts after a fault has been exceeded:
operation is not allowed.
A phase or motor lead between the inverter and motor is
open. The open phase in question will be displayed on the
OPU/keypad. Operation will be prohibited.
A fault occurs if there are unbalanced phase currents from
the inverter to the motor. The fault results in a coast stop.
If the output current exceeds the value in parameter C06
(Stall prevention level during accel/decel), acceleration/
deceleration is decreased until current reaches the limit set by
parameter C06.
If the output current exceeds the value in parameter C05
(Stall prevention level at constant speed), the inverter output
frequency is decreased until the output current is within limits
set by parameter C05; the preset frequency is resumed.
Excessive DC bus voltage is present due to regeneration
(exceeding the braking capacity). The deceleration frequency
is slowed to prevent a DC bus over-voltage fault; deceleration
is resumed upon the decrease in the DC bus voltage. Current
limit stall prevention is also active due to over-current during
decel. The current level can be set by parameter C06.

GUIDELINES FOR PERIPHERAL
EQUIPMENT
Circuit breaker
Wiring practices
Install a circuit breaker on the power supply side of the
inverter for protection of the wiring. Refer to the
National Electric Code or any local electric codes for
proper sizing requirements. Refer to the table on page
13 for standard selection.
1. Long cable lengths from the inverter to the motor
will produce a significant voltage drop across the
cable. This voltage drop will affect the generated
torque of the motor. Properly size the cable
according to the National Electric Code or local
electric codes.
Primary-side contactor
An electromagnetic contactor (MC) can be used on the
primary side of the inverter, but do not use the
contactor to start/stop the inverter. If the contactor
opens and removes power to the inverter, the motor
will coast to a stop. If a DBR, dynamic braking resistor
with braking unit, is used in conjunction with an MC,
install proper controls to remove the MC from the
circuit when the thermal relay contact of the braking
unit is activated. That is, do not open the MC during a
dynamic breaking operation.
Secondary-side electromagnetic contactor
If an electromagnetic contactor is installed between
the inverter and motor, do not open/close the
contactor during operation of the inverter. Using a
contactor between the inverter and the motor is not
recommended.
Thermal relay
An electronic thermal relay is incorporated in the
inverter. If multiple motors are operated with one
inverter, individual thermal relays must be installed for
each motor. A value set for 1.1 times the rated motor
current at 60 Hz operation of the motor is
recommended for the operating current of the thermal
relay.
Power factor correction
Installation of power factor correction equipment is not
recommended on the input or output side of the
inverter.
RFI interference
High frequency signals due to harmonics from the
inverter circuit may cause interference with control
wiring or communication equipment (AM wave) used
near the inverter. Installation of an LC filter, capacitive
filter, and zero-phase reactor is recommended to
minimize the effects.
62
2. Control wiring between the remote frequency/
speed potentiometer and the inverter should be
less than 30 meters. Use twisted and shielded
wiring installed in conduit separate from the motor
wiring. Follow established wiring practices per the
National Electric Code or any local electric codes.
Do not run control wiring in the same conduit or
wire-way with input or output AC power wires.
Maintain a minimum separation of 36 inches
(1 meter) between parallel conduits carrying input
power or motor leads and conduits carrying control
wires. If it is necessary for power and control wiring
to cross, cross at a 90° angle and maintain as
much separation as possible.
3. Conductors from the inverter output to the motor
must be run in metallic conduit or covered metal
wire-way to minimize radiated electrical
interference which could affect nearby electronic
devices or cause interference in communication
devices. Conduit must be properly grounded. In
some installations with sensitive electronic
equipment, it may be necessary to use shielded
cable for the motor conductors. Do not run leads
from multiple drives to multiple motors in the same
conduit.
4. Do not run motor leads in the same conduit as
input power leads. Switching noise on the motor
leads will be coupled into the AC line.

system as the MC coil. To prevent damage to other
components from this voltage transient install a surge
arrestor across the MC coil.

AC REACTOR
(Installation)
Install an AC reactor on the primary side if the inverter
installation conditions are as follows:
The power transformer rating exceeds 500 kVA.
If the rated transformer current exceeds 30 times the
inverter current, a large peak current will be applied to
the input rectifier section leading to possible failure of
the inverter. To prevent damage from these peak AC
currents, an AC line reactor must be installed. Pay
particular attention with the larger capacity inverters
due to the frequent operation with large transformers in
series with the inverters.
Unexpected changes in the supply voltage may be
encountered.
T
Example: If power factor correction capacitors are
suddenly applied to the input power supply on the high
voltage side of the power system.
Phase control equipment is installed in the same power
supply system as the inverter.
The supply voltage is unbalanced.
Power factor correction capacitors are installed in the
power supply system supplying the inverter.
Power factor correction of the power supply is
necessary.
Installation of an AC reactor will improve the power
factor power system.
Harmonic frequency suppression is required.

Input/output filter
The input/output filters are installed to reduce the
electrical noise level from the inverter and prevent
adverse electronic effects to peripheral equipment.
The standard input-side filters are the LC-type filters,
zero-phase reactor, and capacitive (XY) filter; while the
standard output-side filter is the zero-phase reactor.
LC filter: Attenuates most electrical noise from the
inverter.
Zero-phase reactor: Effective at lowering the electrical
noise transmitted from the input power source.
Capacitive filter: Effectively lowers the noise level in the
AM radio frequency band.

Notes:
• The maximum temperature of the braking resistor is approx. 150°C.
Heat-resistant wire is required. Optional Dynamic Braking resistors
must be mounted in an area where heat build-up from the resistors
will not raise the ambient temperature above the inverters rating.
• The maximum wire length shall be 5 meters (16 ft). Use twisted
wire.
• Improper connection of P, N, and PR will lead to failure of the

• Heavy-duty cycle operation of the resistors can result in resistor
temperatures in excess of 300°C. The resistors must not be located
near any flammable material or mounted on a surface which could
be damaged by radiated heat in this temperature range. Severe
burns may result from contact with the resistors in addition to
possible electric shock.

The above examples show jumper installation when the inverter supply voltage is 200/220 V and 400/440 V.
Precautions
1. Remove the jumpers from E1-TA and E2-TC if
thermal relay output terminals TA, TB, and TC are
used in external circuits.
(16 ft) and the distance between the braking unit and
braking resistor shall also be less than 5 m (16 ft.).
Wiring to be twisted. When two or more braking
units are used, use twisted wire for M1, M2, S1
and S2.
2. When two or more braking units are used, switch the
jumpers from the master (DBM) to the slave (DBS),
and vice-versa. If one braking unit is used set the
jumper in the master (DBM) configuration. The
original setting is DBM. If the power supply is 230
VAC for the 200 V class or 380 V/460 V for the
400 V class, properly configure the jumpers for the
applied voltage. Original settings are 200/220 V for
the 200 V class and 400/440 V for the 400 V class.
6. Install the braking resistor in a well-ventilated area.
3. If two braking units are used, connect the P and N
terminals from the braking units to the P and N
terminals on the inverter.
9. Do not touch terminals or jumper pins if the charge
lamp is lit even after the power is turned OFF.
4. The wiring distance between the inverter and
braking unit must be less than or equal to 5 meters
70
5. Do not locate near flammable material as the
temperature rise of the braking resistor may exceed
150°C.
7. Incorrect connection of terminals P, N, and PR will
result in failure of the inverter and braking unit.
8. When resistors other than those specified are
connected, the braking unit may inadvertently fail.

Calculation of
equivalent capacity
YES
The “equivalent capacity” is calculated by converting the capacity of the user’s higher
harmonic generator into the capacity of a 6-pulse converter and totaling the capacity of
each equipment. The following formula is used for calculation.
Po = ∑ KiPi
Po: Equivalent capacity (conversion into 6-pulse converter)
Ki: Conversion factor (Table 1)
Pi: Rated capacity (kVA) (Table 2)
