What is the cause and method of rectifying Err 50.1 external scale communication data fault protection?

ANSWER
■ Cause
The data from the external scale has generated a communication fault. Primarily data fault caused by EMI. The connection cable with the external scale is in place but communication data is faulty.
■ Action
Secure the power voltage of the external scale DC 5 V ± 5% (4.75 - 5.25 V). Use caution if the connection cable with the external scale is long.
If the motor wire and external scale cable are bundled together, separate them.
