Shielding
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 (dr.39)
With parameter dr.39 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.57 = 7).

Uvar is loadable at X4 and X5 with altogether 110 mA. The +5 V voltage is a stabilized
voltage and loadable at X4 and X5 with altogether 300 mA (see 6.9.2).
