6. TROUBLESHOOTING
POINT
Alarms and warnings are basically the same as those of MR-J3- B servo
amplifier. This chapter describes the contents different from those of MR-J3-
B servo amplifier.
As soon as an alarm occurs, make the servo off status and interrupt the main
circuit power.
Remedies for warnings are the same as those of MR-J3- B servo amplifier.
Refer to chapter 8 of the MR-J3-
B Servo Amplifier Instruction Manual.
If an alarm has occurred, refer to this chapter and remove its cause.
6.1 Alarms and warning list
When a fault occurs during operation, the corresponding alarm or warning is displayed. Refer to section 6.2 of
this manual and section 8.2 of the MR-J3-
B Servo Amplifier Instruction Manual at an alarm occurrence and
section 6.3 of this manual and section 8.3 of the MR-J3-
B Servo Amplifier Instruction Manual at a warning
occurrence, and then take the appropriate action. When an alarm occurs, the 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. The alarm is automatically canceled after removing the cause of occurrence.

Note 1. 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. Set parameter No.PE03 to "1
" to deactivate.
