Check/action method
Noise from the power supply may have caused the failure. Disconnect the
cables except for the control circuit power supply, and 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.
