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.
Note
Make sure that the cable length between the digital outputs and the load does not
exceed a permissible max. length of 30 m.
