Motion control C3F_T40

Solution:
Explanation:
Coupling from 0 on (CamIn.CouplingPosition = 0), decoupling on 360°
(CamOut.StandstillPosition = 360°).
The curve generator (C3_CamTableSelect) is started in relative Mode with the
Input I2.
with MasterOffset = 0, the next zero crossing is waited for if the master is already
running.
The busy output of CTS1 starts the coupling sequence before the selected curve
is active. Only if the master position has exceeded the value 0
(CTS1.MasterOffset = 0, CTS1.MasterAbsolute = TRUE), the curve starts to run
and CTS1.Done will become TRUE.
After the 3rd impulse "EndOfSegment" of the C3_CamTableSelect module, the
4th curve is already running. The change of cam to the single mode is then
triggered with the counter module. This will become active at the end of the 4th
curve, so that the curve is run through 5 times.
If the change to the 5th curve cycle has been executed, the Done output will
come to this module (CTS2), which will trigger the decoupling sequence.
