Signal ALM+ is output when the Servopack de-
tects an alarm.
Form an external circuit so that this alarm output
(ALM) turns the Servopack main power OFF.
ON
status:
Circuit between 1CN-31 and 1CN-32 is closed.
1CN-31 is at low level.
Normal state
OFF
status:
Circuit between 1CN-31 and 1CN-32 is open.
1CN-31 is at high level.
Alarm state
Alarm codes ALO1, ALO2, and ALO3 are output to indicate each alarm type.

These signals output an alarm code to indicate the type of an alarm detected by the Ser-
vopack.
Use these signals to display alarm codes at the host controller.
