1.3 Handling methods for alarms/warnings
Check/action method
Check that this alarm occurs in the servo-on status. If the alarm occurs, the
servo amplifier may have malfunctioned. Replace the servo amplifier.
Check the noise, ambient temperature, and others, and implement appropriate
countermeasures for the cause.
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
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 noise, ambient temperature, and others, and implement appropriate
countermeasures for the cause.
If there is noise, take countermeasures to reduce the noise.
Refer to "Noise reduction techniques" in the following manual.

Check/action method
After checking the conditions of the rotary switches, cycle the power, and then
check the repeatability. If the failure continues, the servo amplifier may have
malfunctioned. Replace the servo amplifier.
Check the noise, ambient temperature, and others, and implement appropriate
countermeasures for the cause.
If there is noise, take countermeasures to reduce the noise.
