H1: Manual traversing

17.16 Data lists

By evaluating the signal, it is possible to reduce the overtravel of an axis traversed via the
handwheel, due to the handwheel pulses that have been collected in the control but not yet
transferred to the interpolator for traversing purposes. To do this, deletion of the distance-to-go
must be triggered for the relevant axis or in the channel when a stationary state is detected:
● DB31,... DBX2.2 = 1 (axial delete distance-to-go)
● DB21,... DBX6.2 = 1 (channel-specific deletion of distance-to-go)
