MasterAbsolute
If this input is TRUE, the cam will be started at the current master position. This point can
therefore also be located in the middle of the cam. If the point is outside the range
specified by the cam, an error will be reported.
If this input is FALSE, the cam will be shifted to the current position, i.e. the zero point of
the cam will henceforth be the current master position. Cams whose master range does
not include 0 cannot be used with this mode, because an error would be reported (master
out of specified range).
SlaveAbsolute
This input relates to the StartMode input of MC_CamIn. The following table describes how
it affects the start mode.
See CamIn.StartMode for a more detailed description of the modes MC_CamIn

.
5.6.1.2 MC_CamIn
MasterOffset, - MasterScaling
These two settings apply the following formula to transform the master position and use
the transformed position to evaluate the cam:
MasterScaling > 1 increases the speed at which the cam is processed (compressed), < 1
stretches the cam.
SlaveOffset, - SlaveScaling
These two settings shift and stretch a cam in the slave direction. The cam is first stretched
and then shifted.
SlaveOffset > 1 will increase the size of the slave movement (stretching the cam); < 1
compresses the cam.
