POINT
Alarms and warnings are basically the same as those of the MR-J3- B servo
amplifier. Here, items different from the MR-J3-
B servo amplifier are
described.
As soon as an alarm occurs, make the Servo off status and interrupt the main
circuit power.
If an alarm/warning has occurred, refer to this chapter and remove its cause.
7.1 Alarms and warning list
When an fault occurs during operation, the corresponding alarm or warning is displayed.
If any alarm has occurred, refer to Section 7.2, and Section 8.2 of the MR-J3-
B Servo Amplifier Instruction
Manual; if any warning has occurred, refer to Section 7.3, and Section 8.3 of the MR-J3-
B Servo Amplifier
Instruction Manual, and take the appropriate action. When an alarm occurs, ALM turns OFF.
After its cause has been removed, the alarm can be deactivated in any of the methods marked in the alarm
deactivation column.

Note1. Deactivate the alarm about 30 minutes of cooling time after removing the cause of occurrence.
2. In some controller communication status, the alarm factor may not be removed.
3. The alarm can be deactivated by setting parameter No.PS04 to "1
