Cause

Check/action method

Model

1.

There is a problem with the current detection 
circuit.

Check that this alarm occurs in the servo-on status. If the alarm occurs, the 
servo amplifier may have malfunctioned. Replace the servo amplifier.

[JET-G]

2.

There is a problem with the surrounding 
environment.

Check the noise, ambient temperature, and other conditions, 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-JET User's Manual (Hardware)

Cause

Check/action method

Model

1.

The recognition signal of the servo amplifier 
was not read properly.

Disconnect all cables except for those for the power supply, then check the 
repeatability. If the failure continues, the servo amplifier may have 
malfunctioned. Replace the servo amplifier.

Cause

Check/action method

Model

1.

There is a problem with rotary switches (SW1/
SW2).

After checking the conditions of the rotary switches, cycle the power, then 
check the repeatability. If the failure continues, the servo amplifier may have 
malfunctioned. Replace the servo amplifier.
