L_TT1P_CrossCutter: Unexpectedly high acceleration during declutching (eliminated from V3.18.0)

Eliminated from:
Libraries: L_TT1P_TechnologyModules_LM from V03.18.0.33
L_MC2P_MotionControlCam from V03.18.0.38
(Update via Easy Package Manager)

Behaviour of new version:

The decoupling behaviour is carried out as expected (even for short cutting lengths). The axis moves to the parking position and stops there.

Beschreibung What happens?

The acceleration of the drive is unexpectedly high. After that, the drive stops and the "InvalidParameter" error message is displayed.

When does this behaviour occur?

A short cutting length is selected (e.g. lrProductLength = 200).
After two cuts, the technology module is declutched via xSyncCrossCutter = FALSE.

Which products are affected?

L_TT1P_CrossCutter technology module from the L_TT1P_TechnologyModules_LM library (V3.16.02.03 and higher)

Short-term measures:

The described behaviour does not occur if the declutch distance is set as follows: lrMasterSyncOutDist < product length.

Evaluation/recommendations:

The technology module calculates an optimum declutch distance. Since, in this case, the declutch distance is longer than the product length (lrProductLength), the clutch changes to an error status. The drive is thus no longer controlled. Drive setpoint control is subject to a jump.

If the above-described short-term measure is observed, the drive can be decelerated to standstill in a controlled mode.
