DI.ARST
AL011 Encoder error
Trigger condition
and causes
Condition: the encoder produces abnormal pulses.
Causes:
1. Encoder wiring is wrong.
2. Encoder connector is loose.
3. Poor wiring of the encoder.
4. Connection to the encoder is cut off due to interference.
5. Encoder is damaged.
Checking methods
and corrective
actions
1. Check if the wiring follows the instructions in the user manual. If not,
connect the wiring correctly.
2. Check if the CN2 connector and the encoder connector are loose. If so,
reconnect the connectors.
3. Check both of the connections between the encoder and CN2 of the
servo drive to see if there is any poor wiring or damaged wires. If so,
please replace the connector and cable.
4. Please check the communication error status by setting P0.002 to -80.
If the value continuously increases, it means there is interference.
Please check the following:

Make sure the servo motor is well grounded. Please connect the
ground of UVW connector (Green) to the heat sink of the servo
drive.

Check if the connection for the encoder signal cable is normal.
Make sure that you separate the encoder signal cable from the
main power circuit cable to avoid interference.

Use shielded cable for the encoder.
5. If you took all corrective actions but the issue persists, please replace the
motor.
How to clear the
alarm?
Re-power on the servo drive.
