ground it.
4. Check the motor speed and make sure it is within the rated range.
If issue persists, please send your servo drive back to the distributor or
contact Delta.
Re-power on the servo drive.
An error occurs when the encoder is reading data from, or writing data to
EEPROM.
1. Check if the motor is well grounded; make sure the power cable is
grounded to the servo drive heat sink.
2. Make sure the encoder cable is separated from the power supply or any
high-current cables to avoid interference.
3. Use shielded cable for the encoder and pull out the shielded mesh and
ground it.
4. Check the motor speed and make sure it is within the rated range.
If the issue persists, please send your servo drive back to the distributor or
contact Delta.
