The signal inputs of the second encoder interface support only rectangular signals.
Following specifications apply to the endocer interface 2 (X3B):
• max. operating frequency of input f
• internal terminating resistor R
• 2...5 V high level at rectangular signals
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).

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).
