4.6.11 Changing the Switch-Off Difference (JOB 3)
Definition
Changing the switch-off difference allows you to adjust the drive control to adapt to any
changes in the load and mechanical conditions.
Supply the control interface with the new switch-off difference, and activate JOB 3.
The 1PosInc/Analog accepts the preset switch-off difference.
The switch-off difference remains valid until the parameter assignment of the
1PosInc/Analog is changed.

The switch-off point is reached or overshot; positioning is switched off
immediately, and the run is terminated with POS_DONE = 1. In this case, the
destination is sometimes overshot.
