L_TW2P_TechModulesWindingTraversing: 'TensionCtrl' status is not reactivated after interruption by STO (corrected from V3.23.0)

​Corrected from:
Library: L_TW2P TechModulesWindingTraversing (from V03.23.00)
Update via Easy Package Manager

Response of the new version:
When winding mode is requested again, the tractive force is built up after an STO. The state of the TM or the TA is switched to winding mode. 

What happens?
After an interruption of the tension controlled operation by STO no tension is built up despite renewed request of the winding operation. The state of the TM res. the TA is displayed with State = 'StandBy'.  The CiA Operation mode does not change as expected to 0x6061 = 10: Cyclic sync torque mode but remains 0x6061 = 9: Cyclic sync velocity. 

When does the behaviour occur?
The tension-controlled operation (State = 110: TensionCtrl) is interrupted by STO and should then be resumed without any other motion function having been active in the meantime.

Which products are affected?
FAST Library L_TW2P TechModulesWindingTraversing V03.21.00
This library is included in i950 TA Winder Tension-controlled V01.04.xx.

Short-term measures
To resume winding operation after STO, the following workarounds are possible:  
  1. In conjunction with the i950 TA Winder Tenson-controlled
    By parameterizing the 'Reaction inhibit in operation' 0x500A:107 = 2: Warning (Default is 1: No reaction) the TensionControl mode is automatically switched back to after interruption by STO.
  2. In application of the technology module Winder Tension-controlled
    The TM function block L_TW2P_WinderTensionCtrlState must be diabled once and enabled again and then the Tension control mode must be restarted.

Evaluation/Recommendations:
By remaining in the 'StandBy' state after the interruption, the axis is kept at a standstill under speed control. If the line starts up anyway, unwinders may break the web. Rewinder does not wind the material as expected.
