AL07C occurs and is not cleared before power is cycled on the servo drive,
causing the motor to stop operating.
Use DI.ARST to clear the alarm. Once this alarm is cleared, AL07C occurs.
Follow the checking method and corrective action to clear AL07C.
DI.ARST or cycle power on the servo drive.
The number of retry attempts for the encoder to clear the procedure exceeds
11 times.
If the issue persists, set P0.002 to -80 to check the communication quality of the
encoder. If the communication is normal, use DI.ARST to clear this alarm.
DI.ARST or cycle power on the servo drive.
The encoder version read by the servo drive is in error.
N/A
Replace the motor immediately.
Condition: during general operation, this alarm occurs when the servo drive outputs
current that is over the allowable level specified by the firmware. This alarm protects
IGBT from overheating or burning because of the high current.
Cause:
UVW is short-circuited.
1.
Motor wiring is in error.
2.
The analog signal GND for the servo drive is interfered.
3.
