8156
Category: Alarm
Cause
Condition: Encoder temperature exceeds the warning threshold (85°C) but remains within the protective upper limit (100°C). Cause: Encoder overtemperature warning (85°C ~ 100°C).
Corrective action
Set P0.002 to -124 to read the encoder temperature and compare it with the motor temperature. If too high, improve heat dissipation or reduce the operating temperature. If the actual encoder and motor temperatures differ by more than 30°C, return the motor to the manufacturer for repair. Power on again to clear.
