Special response to signals

The movement of the axis under tangential follow-up control to compensate for a tangent jump
at a corner of the path (defined by the movements of the leading axis) can be stopped by the
following signals (e.g. for test purposes):
● NC Stop and override = 0
● Removal of the axis-specific feed enable
