L_TT1P_FlyingSaw: Violation of the lower limit when changing the cutting length (corrected from V3.21.0)

Corrected from:

Library L_TT1P_TechnologyModules_LM V3.21.0.6
together with L_MC1P_MotionControlBasic V3.21.0.102
(Update via EASY Package Manager)

Response of the new version:

The profile is calculated so that the travel range limit of the saw carriage "lrLowerLimit" is not exceeded.

What happens?

The travel range limit of the saw carriage 'lrLowerLimit' is exceeded.

When does the behaviour occur?

The parking position 'lrParkPosition' is set to the travel range limit 'lrLowerLimit'.
After a cut, the saw carriage is positined to the park position 'lrLowerLimit'. In the deceleration phase a new mark is detected via TP sensor, which is located shortly before the lrLowerLimit.
The TM synchronizes to the new mark without reaching standstill.

Which products are affected?

Function block L_TT1P_FylingSaw from library L_TT1P_TechnologyModules_LM

Short-term measures:

Define the parking position 'lrParkPosition' after the driving range limit 'lrLowerLimit':
'lrParkPosition' > 'lrLowerLimit'.

Evaluation/Recommendations:

The occurrence probability of the error behavior is very low. Considering the short term measure, the error behavior can be bypassed by parameterization.
