4.5 Forming a Protective Sequence
This section describes the procedure for using I/O signals from the SERVOPACK to form a pro-
tective safety sequence.
4.5.1 Using Servo Alarm and Alarm Code Outputs
The basic procedure for connecting alarm output signals is described below.
Provide an external input power supply; the SERVOPACK does not have an internal 24-V
power supply.
The use of the photocoupler output signals is described below.
These alarms are output when a SERVOPACK alarm is detected.
