L_TT1P_CrossCutterState: Sporadic cutting error (corrected from V3.15.0)

Corrected from:
L_TT1P_TechnologyModules_LM (V3.15.0.32)

Response of the new version:

The technology module accepts the marks during zero crossing of the master axis. Cutting is initiated at the mark position.

What happens?

The cross cutter sporadically waits after a mark. In this case, the cut will be performed at the wrong position.

When does this behaviour occur?

The behaviour occurs if TP is detected exactly at the time when the master axis position changes from its maximum value to zero (i.e. e.g. from 360 --> 0).

Which products are affected?

L_TT1P_CrossCutterState in the L_TT1P_TechnologyModules_LM library (V3.14.2.58 and higher)

Short-term measures:

Delay the rising edge at the xMarkReceive TM input by one or two PLC clock cycles when the master axis reaches zero crossing.
