L_TT1P_ElectricalShaft: Slave axis does not reach target position when declutching (corrected from V3.13.1)

Corrected from:
L_TT1P_TechnologyModules_LM (V3.13.1.25)
 
Response of the new version:
If the master axis is stopped in the declutch phase, the coupling ratio and the coupling state can be checked via the xSynchronised or the xAccDecSync output. If one of the outputs xSynchronised or xAccDecSync is active, the master and the slave axis are coupled. With the "Immediate declutching" function, the slave axis can be declutched immediately from the master axis.

For "Immediate declutching", set the xSyncOutInstant input.  

 

What happens?
When declutching, the declutch position of the slave axis "scPar.lrSlaveSyncOutPos" is not reached.

When does this behaviour occur?
The master axis stops during the declutch phase. Due to the position coupling, the slave axis is stopped as well. Thus, the declutch process is not completed.  
 
Which products are affected?
L_TT1P_FlexCamState and L_TT1P_FlexCamHigh function block,
L_TT1P_VirtualMasterHigh function block
in the L_TT1P_TechnologyModules_LM library (V3.9.0.62 and higher) 
in the L_TT1P_TechnologyModules_SM3 library (V3.8.0.23 and higher) 
 
Short-term measures:
The master axis should remain in motion as long as the declutch process has not been completed (xAccDecSync = TRUE).
 
Evaluation/recommendations:
The described behaviour is the desired behaviour of position coupling. The synchronisation process (clutch-in and declutch phase) can only be achieved when the master is in motion.  The synchronisation process is active as long as the xAccDecSync state is set to TRUE. I.e., the slave axis always depends on the motion of the master axis.
