What is the cause and method of rectifying Err 23.0 encoder communication data fault protection?

ANSWER
■ Cause
Even though the data from the encoder is not causing faulty communication, the data content contains errors. The cause is primarily due to EMI. The encoder cable is connected but the communication data is abnormal.
■ Action
Secure the encoder power voltage DC 5 V ± 5% (4.75 - 5.25 V).
Use caution if the encoder line is long → Double or triple wiring of DC 5 V.
If the motor wire and encoder wire are bundled together, separate them.
Connect the shield to FG.
