This section describes the procedure for using I/O signals from the Servopack to form a protective
safety sequence.
The basic procedure for connecting alarm output signals is described below.
Photocoupler output
(per output )
Maximum operating voltage:
30 VDC
Maximum output current: 50 mA
DC
Open collector output
(per output)
Maximum operating voltage:
30 VDC
Maximum output current: 50 mA
DC
A suitable external I/O power supply must be provided by the user separately because there is
no internal 24-V power supply in the Servopack.
The use of the photocoupler output signals is described below.
Output ® ALM+ CN1-31
Output ® ALM-- CN1-32
These alarms are output when a Servopack alarm is detected.

Turns power OFF.
Form an external circuit so this alarm output (ALM) turns the Servopack OFF.
ON:
Circuit between CN1-31 and 32 is closed,
and CN1-31 is at low level.
OFF: Circuit between CN1-31 and 32 is open, and
CN1-31 is at high level.
