1.3 Handling methods for alarms/warnings
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 motor.
Replace the servo amplifier.
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.
