L_TT1P_FlexCAMState: Slave reverses when clutching in (eliminated from V3.17.0)

Eliminated from:
Libraryk:  L_TT1P_TechnologyModules_LM (FAST Motion)  from  V03.17.0.47
                      (Update via Easy Package Manager)
No correction for L_TT1P_TechnologyModules_SM3 (L-force Motion) 
 
Behaviour of new version:
The slave axis engages the master axis without reversing. The current position and the position of the master axis can be in any position.
 
What happens?
L-Force Motion:
The slave axis reverses during the clutch-in process although the parameter (ePosCtrlDirection = L_TT1P_Direction.DirectionMaster) is set.
 
FAST Motion:
Selecting the parameter (ePosCtrlDirection = L_TT1P_Direction.DirectionMaster) and different cycle lengths of Y and slave axis may lead to position step changes of the slave axis during the clutch-in process.  
 
When does this behaviour occur?
The described behaviour only occurs when selecting the coupling mode eSyncMode = ramp_pos and the parameter  (ePosCtrlDirection = L_TT1P_Direction.DirectionMaster) .
 
Which products are affected?
L_TT1P_FlexCAM technology module from L_TT1P_TechnologyModules_LM library (V3.9.0.62 and higher)
L_TT1P_FlexCAM technology module from L_TT1P_TechnologyModules_SM3 library (V3.9.0.9 and higher)
 
Short-term measures:
The slave axis must only be clutched in when the master position is ahead of the slave position. As an alternative, you may use the AxisBasicControl function (scControlABC.xMoveAbsExecute) to position the slave axis one cycle forward to the beginning of the curve.
 
Evaluation/recommendations:
If the above-described short-term measure is observed, the function of the FlexCam technology module is provided.
