Command is not complete when the barcode is written to the encoder.
Check if the wiring is correct and firmly connected. If not, correctly connect the
wiring again.
Cycle power on the servo drive.
When the encoder is powered by the servo drive: over 8,800 rpm.
When the encoder is powered by the battery: over 10,000 rpm.
Check if the motor is properly grounded. Make sure the power cable is grounded

to the servo drive heat sink.
Make sure the encoder signal cable is separated from the power supply or any
2.
high-current cables to avoid interference.
Use shielded cable for the encoder and pull out the shielded mesh and

ground it.
Check the motor speed and make sure it is within the rated range.

An error occurs when the encoder is reading data from or writing data to
EEPROM.
Check if the motor is properly grounded. Make sure the power cable is grounded
