In this manual we have tried as much as possible to
describe all the various matters.
However, we cannot describe all the matters which must not
be done, or which cannot be done, because there are so
1Vi
many possibilities.
Therefore, matters which are not especially described as
possible in this manual should be regarded as “impossible”.

2. DAILY MAINTENANCE AND MAINTENANCE TOOLS
Check and clean the following items once every 6 months or so for using the AC
spindle motor and AC spindle servo units under a normal condition for a long
time.
Take the check frequency into consideration according to the contamination
degrees in each item.
2.1 AC Spindle Motor
If the ventilation hole, cooling fan, and fan finger guard (net) of the AC
spindle motor become dusty, the radiation efficiency of the motor drops. Clean
the AC spindle motor by using the factory air and a vacuum cleaner.
2.2 AC Spindle Servo Unit
Since a cooling fan is mounted at the upper part of the servo unit, its nearby
resistor and other parts become dusty after a long-time use. If they are dusty,
clean them using the vacuum cleaner or the like.
2.3 Maintenance Tools
2.3.1 Tools used for adjustments
Use tools indicated in Table 2.3.1 (a)
Table 2.3.1 (b) for repairing troubles.

Divide the connection part of the short bar holder into 2 parts by
using cutting pliers or the like, remove the right side part, and
replace the transistor module. Apply a coat of silicon grease
without fail when replacing these parts.

After replacement, mount the short bar holder and mount the lower
PCB onto the short bar holder (See Table 6.2 (b)-(l)).
Recheck the circuit according to procedure 2.

Check the PCB transistor driver circuit.
(1) Turn on the AC input power supply. Don't apply any rotation
commands (SFR,SRV).
(2) Measure the base-emitter voltage of six transistors (U,V,W
phases) by using a circuit tester.
Particularly be careful since a high voltage is applied to the
vicinity of the driver circuit so as not to receive any
electric shock.

3.6 Abnormal Noise is Produced from Motor during Deceleration
During deceleration of the motor, energy is regenerated to the power supply
through the regenerative control circuit (this energy is consumed by resistors
in MODEL 1/2/small MODEL 3)
If the regenerative energy is excessive, the regeneration limiter circuit
operates to change the motor current waveform, causing an abnormal noise to be
produced from the motor.
If such a case, turn RV6 (this is normally set to division 3) counterclockwise
untill no abnormal noise is produced. When RV6 is turned counterclockwise, the
deceleration time increases.

Connect the power cable after protective earth connection.
The power phase rotation is not specified for AC spindle servo unit.
4.3 AC Spindle Motor Connection
Connect the AC spindle motor according to the connection diagram in appendix 1.
If the drive power cable connection sequence is in error, vibrations are
produced or alarm No. 2 occurs to stop the motor. Connect protective earth "G"

MODEL 3 require orientation C (A06B-6052-J120) , (PCB A20B-0008-0030)
is used. This circuit is set and adjusted as follows.
1) Setting and adjustment of setting terminals (SH)
Table 7.3.2 (a) shows the setting and functions of setting terminal (SH).
Select these terminals by user.
Terminal SH01 is provided for adjustment and testing at site. Set this SH01
terminal after turning on the power supply, and disconnect it after
adjustment without fail.
(Make sure that LED7 goes out).

1) Setting and adjustment of setting terminals (SH)
Table 7.3.3 (a) shows the setting and functions of setting terminal (SH).
Select these terminals by user.
Terminal SH01 is provided for adjustment and testing at site. Set this SH01
terminal after turning on the power supply, and disconnect it after
adjustment without fail.

7.3.5 Method of checking the spindle position loop gain
spindle position loop gain can be checked according to the following
procedure. Check it after adjusting the spindle orientation control circuit.
The
Procedure of checking the spindle position loop gain
1
Set the mode to TEST mode (LED7 ON) after shorting setting terminal SH01
pins
.
2
Release setting terminal SH04 1-2 and 2-3 pins to release the speed
limitation of orientation.
3
Measure spindle revolutions Ns (H) , Ns(L) rpm when SW1 (INITIALIZING
button) is depressed (turned on) and the spindle clutch (gear) is set to
HIGH (*CT *CTH1, 2: Open) and LOW (*CTH1, 2: Closed), respectively.
4
The spindle position loop gain can be obtained by the following formula.
(sec_1)
K (H or L) = N (H or L)
55
s
P
where K (H) : Position loop gain when the spindle is set to HIGH gear
(clutch).
K (L) : Position loop gain when the spindle is set to LOW gear

Adjust the deceleration time so that it is the same as
acceleration time.
Deceleration time is shortened when
setting value is large. Deceleration time gets longer when it
is small. Motor may make abnormal sounds if regenerated power
is excessively large, as the regeneration limit circuit
functions to change the waveform of the motor current. Make
the setting smaller in such a case.

motor becomes less than the (Set data/ 100)% of maximum number
of revolution.

therefore, the machine tool builder should normally check or modify only the
rank A setting.
When changing the operating conditions (change of speed rpm and special

CH13-0V
Give velocity command voltage 0 V (equivalent to S00)
after setting the motor to be ready for operation.
Adjust RV2 while alternately giving the forward rota¬
tion and reverse rotation commands, until the voltage
remains unchanged at measuring terminal. (Note)
Level

Give the rated rotation command 10 V to the motor, and
adjust RV1 until the measuring terminal voltage becomes
+10 V +0.05 V when the spindle forward rotation command

Note) If the voltage at CH13 is +5.0 mV when the spindle rotates forward and
+5.0 mV +1.0 mV when the spindle rotates reversely, the offset error

Note 1) In MODEL 1/2/small MODEL 3, adjust RV9A, 9B during forward rotation or
RV11A, 11B during reverse rotation according to the above procedure.
Note 2) The forward rotation means that the AC spindle motor rotates counter¬
clockwise as viewed from the motor shaft direction and this forward
rotation (SFR) does not always correspond to the forward rotation of the
machine tool spindle.

APPENDIX 10 MAGNETIC SENSOR SIGNALS CHECKING METHOD
1.
APPLICATION
This document applies to the following check procedure by observing output
signals of the magnetic sensor (specification: A57L-0001-0037) employed for
magnetic sensor system spindle orientation.
Check item
Item
1
2
Whether magnetizer, magnetic sensor head, and magnetic sensor amplifier
are defective or not.
Whether magnetizer and magnetic sensor head are properly mounted or
not;
3
2.
Whether magnetic sensor signal cables are properly connected without
any connection failure and short-circuit.
CHECK PROCEDURE
1) Preparation
(T) Rotate the spindle at about 120rpm. Select the counterclockwise rotating
direction as viewed from the AC spindle motor shaft (in such a direction
as the voltage at check terminal CH13 (VCMD) of AC spindle control
circuit PCB becomes positive (+) to CH16 (OV)).
Note) MODEL 1, 2, small MODEL 3

A20B-0009-05 34ÿ0539
MODEL 30, 40
A20B- 1000-0700ÿ0701
(2) Check the peak voltage and offset voltage levels of the following signal
waveforms at the check terminals of the orientation circuit (drawing:
A20B-0008-0030ÿ1 or A20B-0009-0520) using an oscilloscope.
The names of
check terminals and signal contents are common, irrespective of the kinds
of orientation circuit.
