L_TS2P_FlexCAM: The y-axis expansion/compression factor lrSetScalingSlave is factored into scPar.lrSyncVel

Fixed as of:

Behavior of the new version:

Description of behavior:

During the coupling process, different profile parameters are used for the axis's driving profile synchronized to the cam disc than those defined in the parameters
scPar.lrSyncVel, scPar.lrSyncAcc, and scPar.lrSyncDec.

The profile calculation additionally takes the scaling factor into account, even though this factor should not be applied to these parameters.

Conditions under which the behavior occurs:

This behavior occurs when:

the coupling mode scPar.eSyncMode = ProfGenAbs is set
the scaling factor lrSetScalingSlave is set to a value other than 1 (greater than or less than 1)

Affected products:
Library L_TS2P_TechModulesSynchronizingCamming

Short-term measures, Recommendations, Assessment:

When calculating the profile of the slave axis on the cam disc, the scaling factor is incorrectly applied to the profile parameters
scPar.lrSyncVel, scPar.lrSyncAcc, and scPar.lrSyncDec.

This behavior will be adjusted in the future:
The profile parameters (lrSyncVel, lrSyncAcc, lrSyncDec) will no longer be modified by the scaling factor but will remain unchanged.

This results in an incompatible change in behavior regarding profile calculation after the bug fix.

Until the issue is resolved, for applications affected by this behavior, ensure that the scaling factor lrSetScalingSlave remains set to 1 or account for the different behavior when configuring the parameters.
