1: Alignment of the current slave setpoint position from the curve with the current
setpoint position from the history of the Execute of the MC_CamIn
Master Cam input: Master signal at the curve input
(C3Cam.StatusMaster_PositionCamUnits o3030.24)
Master signal: Master signal of the acquisition (C3Cam.StatusMaster_Position
o3030.1)
Slave: Signal at the curve output (C3Cam.StatusOutput_CurvePositionUnits
o3032.24)
If a closed curve is combined with absolute master reference, an entry with
MC_CamIn at a master position > 0 will lead to a backwards movement of the axis
with reference to the start point.
