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.
