"The actual current value is immediately taken over after power is switched on if
both module and encoder are turned on at the same time. If the encoder is turned on
later, however, the current value can assume undefined states and is not taken over
correctly until the AO position is changed.
if pseudo –tetrades occur, then the encoder signal maybe too slow.
Correction: Match delay with C21.
Watch out for correct settinas in accordance with section 5.3.1.
