L_TT1P_VirtualMasterHigh, L_TT1P_ElectricalShaftPos: Sporadic error message 17110 (Master is Reversing)

​Eliminated from:
L_TT1P_TechnologyModules_LM V3.10.0.8
L_TT1P_TechnologyModules_SM3 V3.10.0.7
 

Behaviour of new version:
The noise of an encoder axis does not release the error message 17110 (Master is Reversing). Furthermore, there are additional coupling modes available as a function expansion. For example, the engagement over time clutch mode "ramp_time" couples regardless of the master rotation. 
 

 

What happens?
Sporadically, the error message 17110 (Master is Reversing) is output during the synchronisation process (clutch-in and declutch phase).

 
When does this behaviour occur?
 
The master axis changes its direction of rotation during the clutch-in or declutch phase of the TM (xAccDecSync = TRUE).
 
 
 
Which products are affected?
 
L_TT1P_FlexCamState and L_TT1P_FlexCamHigh function block
 
L_TT1P_VirtualMasterHigh function block
 
in L_TT1P_TechnologyModules_LM library (V3.9.0.62 and higher) 
 
in L_TT1P_TechnologyModules_SM3 library (V3.8.0.23 and higher) 
 
 
 
Short-term measures:
 
As long as the clutch-in and declutch process has not been completed (xAccDecSync = TRUE), the master axis should not change its direction of rotation.
 
 
 
Evaluation/recommendations:
 
As long as the clutch-in and declutch process has not been completed (xAccDecSync = TRUE), the master axis should not change its direction of rotation.
