Rotating direction Parameter for defining the rotating
direction in which there have to be
ascending or descending position
values. Default setting: Ascending position values when looking at the flange
and rotating the shaft clockwise.
Parameter defining the steps per turn as

Cable data
Parameter for setting the encoder to a
requested position value assigned to a
defined shaft position of the system.
The offset of encoder zero point and
mechanical zero point is stored in the
encoder.
