Condition: set value of PM.004 exceeds the allowable range.
Cause: set value of PM.004 exceeds the allowable range.
Check if the set values of PM.000, PM.003, PM.004, and PM.013 match the
1.
specifications of the connected motor.
If the issue persists, set P2.008 to 18 to reset the PM parameters and cycle
2.
power on the servo drive.
Cycle power on the servo drive.
Condition:
The difference between the monitored magnetic field returned by the Hall
1.
sensor and the magnetic field calculated by the servo is too big.
The detection occurs only when the linear motor speed is lower than
2.
100 mm/s or the rotary motor speed is lower than 100 rpm.
Cause: when PM.009 [Bit 4] is set to 1, the servo detects the current magnetic field
position of the motor and compares it with the magnetic field position of the Hall
sensor. When the error between the two is too large, this alarm is triggered.
Check if the Hall sensor is abnormal or there is interference.
1.
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.
Check if the feedback signal has interference causing pulse leakage.
3.
If the encoder feedback type is a square-wave digital signal, check the
4.
following items:
(a) Check if the motor speed is too fast and exceeds the maximum limit of
16 MHz that the hardware can receive (the limit is 4 times the frequency).
(b) Check if the filter setting of P1.074.U is set properly.
Cycle power on the servo drive.
