Alarm function

This function displays an alarm or warning when an error occurs during operation. When an alarm occurs, ALM (Malfunction)
turns off and the servo motor stops. When a warning occurs, the servo motor may not stop for each warning number.
The stop method changes depending on whether the forced stop deceleration function is enabled or disabled. However, even
if the forced stop deceleration function is enabled, the forced stop deceleration may not be effective and the servo motor may
stop with the dynamic brake or other methods, depending on the alarm that has occurred.
After releasing the alarm or warning, resume the operation.
Refer to the following manual for the details of alarms and warnings.

Operation status at alarm occurrence [G] [WG]

The following shows the status of servo amplifiers at alarm occurrence.
Status
The No. of the alarm that has occurred is shown on the 7-segment LED.
When an alarm is detected during operation, the servo motor stops safely with the methods
specified in accordance with the alarm No.
The occurred alarm is recorded as the alarm history. In the alarm history, the latest 16 alarms
are recorded so that the types of alarms that have occurred in the past can be checked.
The conditions of the servo amplifier (such as the servo motor speed and droop pulses)
before/after alarm occurrence are recorded with the drive recorder. This is useful for analyzing
the cause of alarm occurrence.
The ALM (Malfunction) of the output device signal is turned off.
The occurrence status of alarms and warnings can be monitored with MR Configurator2 or via
a network.
