How to clear the
alarm?
To make sure that the source of the feedback signal is correct, check the
1.
PM.003.U setting in the Motor Parameter Identification Wizard.
Check if the feedback signal is abnormal. Use the software scope and select
2.
"Feedback Position [PUU]" as the input signal for the channel to monitor
whether the feedback value is correct.
Make sure the motor and mechanical part can operate properly.
3.
Check if the friction between the motor and mechanical part is too large.
4.
If so, increase the set value of PM.011 by 50% at a time for testing.
Check if the moving distance is too large during the initial magnetic field
5.
detection when the motor is powered on. Use the software scope and select
"Feedback Position [PUU]" as the input signal for the channel to monitor
whether the feedback value is correct. Try reducing the set value of PM.011
Initial magnetic field current detection.
If there is interference, check the following items:
6.
(a) Check if the motor is properly grounded. Make sure the ground end
(green) of the power cable is grounded to the servo drive heat sink.
(b) Use shielded cable for the feedback signal cable. Make sure the signal
cable is separated from the power supply or any high-current cables to
avoid interference.

Condition: if the Motor Parameter Identification Wizard function has not been
executed or the identification failed, once the servo is on, this alarm is triggered.
Cause: the Motor Parameter Identification Wizard function has not been executed
for the motor or the indentification process failed.
Execute or re-execute the Motor Parameter Identification Wizard function.
Switch the servo to the Servo Off state to clear this alarm.
