L_TT1P_FlexCam (Base, State): Exception when clutching in (Eliminated from V3.9.0)

Eliminated from:

L_TT1P_TechnologyModules_SM3 V3.9.0.9

L_TT1P_TechnologyModules_LM V3.9.0.62

Behaviour of new version:

Engaging the cam is executed without exception. Regardless of whether the input xCamChangeInstant is set or not.

What happens?

When clutching in (xSyncCam = TRUE), the following exception occurs:

*EXCEPTION* FPU DivisionByZero Application "Task-Name"

PLC processing is stopped by the exception.

When does this behaviour occur?

The exception occurs if the xCamChangeInstant input of the L_TT1P_FlexCamBase or the L_TT1P_FlexCamState technology module remains TRUE after a cam replacement and declutching (xSyncCam = FALSE) and clutching in (xSyncCam = TRUE) is carried out.

Which products are affected?

PLC Designer from V3.8

L_TT1P_TechnologyModules library V3.8.0.23

Short-term measures/recommendations:

Ensure that the xCamChangeInstant technology module input is set to FALSE when clutching in (xSyncCam = TRUE).

Evaluation:

An exception may occur when clutching in to the curve. In this case, PLC processing will stop. If the above-described recommendation is observed, the function restriction does not occur.
