1.2 Alarm Codes and Troubleshooting Check List

Alarm status, cause, and remedy are listed in the following table to facilitate

troubleshooting of alarm codes.

Note: Some of the repairs, such as replacement of a servo motor or servo pack, require special

training and expertise. Contact a Fuji agent before attempting to perform any of these

procedures. Please have the “Check List for Troubleshooting” available for reference when

contacting a Fuji agent for assistance.

21H Power device Abnormality

(Over current)

U/V/W-phases of amplifier is short circuited due to the

wiring in amplifier and motor. Also, U/V/W-phases are

grounded in the earth.

Check the wiring between the amplifier and motor, and confirm that

there is no error. If some error is detected, modify or change the

wiring.

Short circuit or fault in U/V/W-phases on servo motor

side.

Replace the servo motor.

• Defect in control print panel

• Defect in power device

Replace the servo amplifier.

Overheat is detected in Power device (IPM). • Confirm that the cooling fan motor for the servo amplifier is working.

If it is not working, replace the servo amplifier.

• Confirm that that the temperature of the control panel (ambient

temperature of the servo amplifier) does not exceed 55 degrees.

If in excess of 55 degrees, check the installation method of the

servo amplifier, and confirm that the cooling temperature of the

control panel is set to below 55 degrees.

22H

Electric current abnormality 0

• Defect in control print panel

• Defect in power device

Replace the servo motor.

Servo amplifier and motor are not combined properly. Confirm that the proper codes (per the specified Motor Codes) have

been used for the servo motor; if not, replace the servo motor.

23H

24H

Electric current abnormality 1

Electric current abnormality 2

Defect in internal circuit of servo amplifier Replace the servo amplifier

Malfunction due to noise Confirm proper grounding of the amplifier Add ferrite core or similar

countermeasures against noise.
