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 motor.
(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.
(With the absolute position system,
the zero point must be established.)
