2) Contact Output Signal ALM+, ALM-
Output → ALM+ 1CN-31
Output → ALM- 1CN-32
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 Circuit between 1CN-31 and 1CN-32 is closed.
status: 1CN-31 is at low level.
OFF Circuit between 1CN-31 and 1CN-32 is open.
status: 1CN-31 is at high level.
Alarm codes ALO1, ALO2, and ALO3 are output to indicate each alarm type.
3) Contact Output Signals ALO1, ALO2, and ALO3
Output → ALO1 1CN-37
Output → ALO2 1CN-38
Output → ALO3 1CN-39
Output → SG
