General Function Description
R 02/92
If the selected end value is higher than the initial value, the track identifier bit is set within the cam
(= 1).
If, however, the selected initial value is higher than the end value, the track identifier bit within the
cam is reset (= O).
Outside the cam the applicable track identifier bit is set (= 1).
Example:
I

Track identifier bit = O
Track identifier bit = 1
Track identifier bit = 1
When encoders allow a negative traversing range, the sign must be considered!
Example: –200 initial value and –500 end value
The track identifier bit is inverted (i.e., within the cam = O)!
