Troubleshooting
AL073 Encoder memory error
Trigger condition
and cause
An error occurs when the encoder is reading data from or writing data to EEPROM.
1. Check if the motor is properly grounded. Make sure the ground end (green) of
the power cable (green end) is grounded to the servo drive heat sink.
2. 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
Checking method
and corrective action
cables to avoid interference.
3. Use shielded cable for the encoder cable. Pull out the wire mesh and have it
correctly grounded.
4. Check the motor speed and make sure it is within the rated range.
If the issue persists, send your servo motor back to the distributor or contact Delta.
How to clear the
alarm?
Cycle power on the servo drive.

and cause
The single-turn position in the encoder is in error.
1. Check if the motor is properly grounded. Make sure the ground end (green) of

AL075 Encoder absolute number of revolutions is in error
Trigger condition
and cause
The absolute number of revolutions in the encoder is in error.
1. Check if the motor is properly grounded. Make sure the ground end (green) of
the power cable is grounded to the servo drive heat sink.
2. Check if the connection for the encoder signal cable is normal. Make sure the
