Check/action method
Check if the encoder cable has been disconnected or has shorted. If there is a
problem with the cable, repair or replace the cable.
Replace the servo amplifier.
Replace the servo motor.
Check the power supply for noise. If there is noise, take countermeasures to
reduce the noise.
Refer to "Noise reduction techniques" in the following manual.
MR-J5 User's Manual (Hardware)
Check/action method
Use a servo motor with functional safety.
