2.7.1

Definition of Rotation Direction

The direction of rotation is positive if the direction of rotation and the positive Y – axis of the sensor head are

sensor head. This must be taken into consideration with assembly variations. In the left representation, frontside

of the sensor (=marking) points to multipole ring (=encoder) located behind. For positive direction of rotation the

direction of rotation bit (DR) is set to "0"

.

For better understanding three different modes have to be considered: data protocol at normal speed, at high

speed and standstill. Explanations will follow on next pages.
