Parameters
l P 500[0] - ENC_CH1_ActVal[0].SingleTurnand
l P 500[1] - ENC_CH1_ActVal[1].MultiTurn
are used, for example, to indicate the current position value at the output for encoder
channel Ch1. These parameters can also be used for checking purposes during
commissioning.

The encoder gearing ratio has a multiplicative effect on the position progress, i.e.
either “expanding” or “compressing”.
A distinction can be drawn between an encoder’s motor mode and field mode:
l Motormode:Theencoderisthemotorcommutationencoder
l Fieldencoder:Theencoderisnotthemotorcommutationencoder(instead,it
isanadditionalencoderinthe“field”,e.g.usedforpositioncontrolpurposes)
In motor mode, the encoder gearing is used exclusively to synchronize the motor
shaft with the encoder shaft (default: 1:1 if the shaft is the same). In this case, a
position progress value will be passed to the system at the encoder channel output.
This value will be proportional to the position progress of the motor’s commutation
(adjusted for the pole pair number).
In field mode, the encoder gearing can be used “freely” for scaling purposes.
