The incremental encoder output gives out the signals recorded at the encoder interface
1:1 in RS422-specification over the second channel (e.g. master drive in synchronous
operation).
Operating mode
encoder 2 (ec.20)
With parameter ec.20 it is defined whether the encoder channel 2 shall work as input
or output. Precondition for that is a built-in switch-selectable encoder interface
(In.5†=†7).
