Vibration is occurring.
• Set a filter.
• Lower the speed loop gain
(SV005).
1 Check whether vibration is occurring.
There is no vibration. Investigate item 2.
{
The setting is too large. Set an appropriate value. 2 The speed loop gain (SV005) setting
is larger than the standard value.
The setting is approximately the
same as the standard value.
Investigate item 3.
{
The setting is incorrect. Set the standard value. 3 Check the current loop gain.
(SV009, SV010, SV011, SV012)
The standard value is set. Investigate item 4.
{
The power cable is short-circuited. Replace the motor power cable. 4 Disconnect the UVW phase wiring
from the terminal block, and the
cannon plug from the motor. Check
the insulation with a tester.
There is no problem. Investigate item 5.
{
There is a ground fault at the power
cable.
Replace the motor power cable. 5 Check the insulation between the
motor power cable and FG.
There is no problem. Investigate item 6.
{
There is a ground fault in the motor. Replace the mot or.
(With the absolute position system,
the zero point must be established.)
6 Connect the cannon plug, and check
the insulation between the power
cable and FG.
There is no problem. Investigate item 7.
{
No abnormality is found in particular. Replace the drive unit. 7 Check if there is any abnormality in
the motor's ambient environment.
(Ex. Ambient temperature, cutting
water)
An abnormality was found in the
ambient environment.
Improve the installation environment.

Power module overheat
The power module's temperature protection function activated.
Investigation details Investigation results Remedies SV SP
The fan is rotating, and an alarm did
not occur again.
Continue to use.
The power may be turned ON without
assuring more than 10 seconds for
the time from when the power is
turned OFF till when it is turned ON.
Leave for more than 10 seconds or
more, and turn the power ON again.
1 Turn the unit power ON again, and
confirm the rotation of the fan.
Note) Assure more than 10 seconds
for the time from when the
power is turned OFF till when it
is turned ON. For the fan used
for the drive unit, assuring
more than 10 seconds for the
time from when the power is
turned OFF till when it is turned
ON is required.
The fan did not rotate. Or, an alarm
occurred again.
Investigate item 2.
{ {
Large amounts of cutting oil or cutting
chips, etc., are adhered, or the
rotation is slow.
Clean or replace the fan. 2 Confirm adhesion of cutting oil or
cutting chips, etc. at the fan. Or check
if there is any abnormality such as
low rotation speed.
The fan is rotating properly. Investigate item 3.
{ {
Cutting oil or cutting chips, etc., are
adhered, and the fins are clogged.
Clean the fins. 3 Check whether the heat dissipating
fins are dirty.
The fins are normal. Investigate item 4.
{ {
55°C or more Improve the ventilation and cooling
for the power distribution panel.
4 Measure the drive unit's ambient
temperature.
Less than 55°C. Investigate item 5.
{ {
No abnormality is found in particular. If the alarm occurs even after the unit
temperature has dropped, replace
the unit.
5 Check if there is any abnormality in
the unit's ambient environment.
(Ex. Ambient temperature, noise,
grounding)
An abnormality was found in the
ambient environment.
Take remedies according to the
causes of the abnormality.
Ex. High temperature:
Check the cooling fan.
Incomplete grounding:
Additionally ground.

There is abnormal noise. Investigate item 4.
(The initial pole estimate may be
incorrect.)
2 Is there any abnormal noise when
starting?
There is no abnormal noise. Investigate item 3.

• Is the cable connected to the motor
for another axis?
• Is the contactor between the drive
unit and motor OFF?
(When using coil changeover
specifications.)
The connections are correct. Investigate item 5.

The cutting load is large. Lower the cutting load. 5 Check the load value with the spindle
monitor, and investigate the
machine's load state.
The cutting load is not large. Investigate item 6.
