Check/action method
Noise from the power supply may have caused the failure. Disconnect all
cables except for those for the control circuit power supply, then check the
repeatability. If the failure continues, the servo amplifier may have
malfunctioned. 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.
