P1.008), moving filter (P1.068), low-frequency vibration suppression (P1.025 -

Condition: when the value of the E-Gear ratio exceeds the range (1/4 - 262144),
this alarm occurs once power to the servo drive is cycled.
Cause: when the servo drive is powered on, E-Gear ratio value is in error.
Check if the value for the E-Gear ratio is within the allowable range (1/4 - 262144).
Correct the value and then cycle power on the servo drive.
Cycle power on the servo drive after the value is corrected.
Use the Motor Parameter Identification Wizard and the identification is complete.
Cycle power on the servo drive.
Cycle power on the servo drive.
Condition: error occurred when using the Motor Parameter Identification Wizard
functions.
Cause:
When the motor is executing the Motor Parameter Identification Wizard functions,
this alarm is triggered if the friction is too large causing the motor unable to run,
or input values of the resolution and magnetic pole pitch are too large.
Check if PM.003, PM.004, and PM.045 are set correctly according to the
1.
specifications.
Make sure the motor can operate properly.
2.
Check if the friction between the motor and mechanism is too large.
3.
Check if the feedback signal is abnormal. Use the software scope and select
4.
Feedback position [PUU] as the channel type to monitor whether the feedback
value is correct.
Check for interference causing pulse leakage.
