FM 453 Servo Drive / Step Drive Positioning Module
C79000-G7076-C453-01
The FM 453 provides four digital outputs per channel.
All outputs have equal priority. Switching functions are allocated to an output
number by way of machine data.
These four outputs are intended for wiring of application-specific signals.
Possible uses include:
S
Position reached and stopped
S
Switching function M command
S
Forward/backward rotation
See Section 5.3.1 for further applications.

A 24 V auxiliary voltage that has the parameters listed above must be con-
nected for digital outputs and encoders with 5 V or 24 V supply voltages.
!
Danger
The 24 V auxiliary voltages 1L+ to 4L+ must be implemented as functional
extra-low voltages with safe isolation to EN60204-1, Section 6.4, PELV
(with grounding 1M, 2M).
