POINT
Refer to "MELSERVO-J4 Servo Amplifier Instruction Manual (Troubleshooting)"
for details of alarms and warnings.
As soon as an alarm occurs, make the Servo-off status and interrupt the main
circuit power.
[AL. 37 Parameter error] and warnings (except [AL. F0 Tough drive warning]) are
not recorded in the alarm history.
When an error occurs during operation, the corresponding alarm and warning are displayed. When an alarm
or warning is displayed, refer to "MELSERVO-J4 Servo Amplifier Instruction Manual (Troubleshooting)" to
remove the failure. When an alarm occurs, ALM will turn off.
8.1 Explanation for the lists
(1) No./Name/Detail No./Detail name
Indicates each No./Name/Detail No./Detail name of alarms or warnings.
(2) Stop method
For the alarms and warnings in which "SD" is written in the stop method column, the servo motor stops
with the dynamic brake after forced stop deceleration. For the alarms and warnings in which "DB" or
"EDB" is written in the stop method column, the servo motor stops with the dynamic brake without forced
stop deceleration.
(3) Alarm deactivation
After the cause of the alarm has been removed, the alarm can be deactivated by any of the methods
marked
in the alarm deactivation column. Warnings are automatically canceled after the cause of
occurrence is removed. Alarms are deactivated with alarm reset, CPU reset, or cycling the power.
Alarm deactivation Explanation
Alarm reset 1. Reset command from controller
2. Clicking "Occurred Alarm Reset" in the "Alarm Display" window of MR
Configurator2
CPU reset Resetting the controller itself
Cycling the power Turning the power off and then turning it on again.
