Here, a reversal of the direction of motion is prevented from occurring when
the compensation movement is carried out (specified by master setp. 1/2).
The speed remains at V=0 until the incoming master setp. has reached
the path and the ramp is active again.

z 0 Changeover of master setpoints and simultaneous offset of correction
can only be carried out one after the other
