and set the correct values.
DI.ARST
Condition: the encoder produces abnormal pulses.
Cause:
Encoder wiring is wrong.
1.
Encoder connector is loose.
2.
Poor wiring of the encoder.
3.
Connection to the encoder is cut off due to interference.
4.
Encoder is damaged.
5.
Check if the wiring follows the instructions in the user manual. If not, connect
1.
the wiring correctly.
Check if the CN2 connector and the encoder connector are loose.
2.
If so, reconnect the connectors.
Check both of the connections between the encoder and CN2 of the servo
3.
drive to see if there is any poor wiring or damaged wires. If so, replace the
connector and cable.
Check the communication error status by setting P0.002 to -80. If the value
4.
continuously increases, it means there is interference. Check the following:
 Make sure the servo motor is properly grounded and connect the ground
of the UVW connector (green) to the servo drive heat sink.
 Check if the connection for the encoder signal cable is normal. Make sure
the encoder signal cable is separated from the power supply or any
high-current cables to avoid interference.
 Use shielded cable for the encoder.
If you took all corrective actions but the issue persists, replace the motor.
5.
Cycle power on the servo drive.
Condition: the calibration value exceeds the allowable value during electric
calibration.
