Check if the motor power cable (U, V, W, GND) is firmly connected. Please
connect wiring and ground properly by following the instructions in this user
manual.
Cycle power on the servo drive.
Condition:
1. Internal communication error for the absolute type encoder.
2. Internal error for the other type of encoder.
Cause: encoder internal communication error.
1. Check the battery wiring. Then wire it again and cycle power on the
system.
2. Internal communication error for the absolute type encoder occurs.
Please replace the motor.
Cycle power on the servo drive.
Condition: encoder temperature is over the maximum of 100℃.
Cause: encoder temperature is over 100℃.
Set P0.002 to 120d in order to read the temperature and check if it is below
100℃. If the encoder temperature is higher than 100℃, please improve the
heat dissipation or reduce the operating load. If the temperature difference
between the motor and the displayed temperature value is over 30℃,
please send the motor back to the distributor.
After the temperature detector shows a temperature below 100℃, please
cycle power on the servo drive.
Excessive deviation of full closed-loop position control
1. Check the value for P1.073. If the value is too low, please set a higher
value.
2. Make sure the connector is firmly connected and there is no problem in
connecting the mechanism.
