5.5 Forming a Protective Sequence
This section describes the procedure for using I/O signals from the servo amplifier to form
a protective safety sequence.
5.5.1
Using Servo Alarm and Alarm Code Outputs
The basic procedure for connecting alarm output signals is described below.
A suitable external I/O power supply must be provided by the user separately
because there is no internal 24V power supply in the servo amplifier.
The use of the photocoupler output signals is described below.
These alarms are output when a servo amplifier alarm is detected.
Form an external circuit so this alarm output (ALM) turns OFF the servo amplifier.

ON
Circuit between CN1-31 and 32 is closed, and
CN1-31 is at low level.
Normal state.
OFF
Circuit between CN1-31 and 32 is open, and
CN1-31 is at high level.
Alarm state.
