10. Alarm
10.1 Alarm/Warning List
When an error occurs during operation, an alarm or a warning is displayed. When an alarm or a warning
occurs, take the proper action as described in the "MR-J4-_B_RJ020/MR-J4-T20 Servo Amplifier Instruction
Manual".
After removing the cause of the alarm, the alarm can be canceled using any of the methods marked with
○
in the alarm reset column in the table below. (The shaded parts indicate the differences.)

Note 1. After the cause of the alarm is removed, leave it to cool for about 30 minutes.
2. To confirm connection to the servo system controller, the alarm may not be reset if the power is not turned on twice or more.
3. It is only reset when mode is set correctly.
4. Alarm factors may not be removed depending on the cause of the alarm.
5. Numerical figures after a decimal point may not be displayed.
6. There are two stop methods of DB and EDB.
DB: Stop with a dynamic brake
EDB: Stop with an electronic dynamic brake (Only available for the specific servo motor)
Refer to the following table for specific servo motors. The stop method other than the specific servo motor is DB.
Series Servo motor
HG-KR HG-KR053/HG-KR13/HG-KR23/HG-KR43
HG-MR HG-MR053/HG-MR13/HG-MR23/HG-MR43
HG-SR HG-SR51/HG-SR52
7. When STO1 or STO2 is turned off (the CN8 short-circuit connector is disconnected), the stop method is DB.
Display Name Description Cause Action
3E.2 Mode change
error
The operating mode setting does
not match the actual operating
mode. Switched on with the MR-J4-T20
removed. 1. Connect the MR-J4-T20 and restart the servo
amplifier.
2. With the application of "MR-J4(W)-B Change
mode” supplied with the MR Configurator2,
change to "J2S Compatibility Mode".
