L_MC2P - MC_GearIn: Incorrect clutch-in of slave, clutch-in may not be possible (corrected from V3.12.0)
Corrected from: - Library: L_MC2P_MotionControlCam V03.12.00.35 (contained in PLC Designer V03.12.00.177 and higher)
Response of the new version: The faulty behaviour has been corrected.
What happens?
When repeatedly activating the MC_GearIn FB (Execute edge), clutch-in is not always performed with the selected acceleration parameters, but with a speed and position step change.
After this, the 'InGear' output signal will not be set.
When does this behaviour occur?
The behaviour occurs if the 'Continuous Update' function has been used at least once and
MC_GearIn is requested again without changing the input parameters compared to the previous request.
Which products are affected? - FAST Motion L_MC2P_MotionControlCam library - MC_GearIn FB
(contained in the PLC Designer)
Short-term measures:
Before requesting the MC_GearIn FB again, change at least one input parameter (RationNumerator, RationDenominator, MastervalueSource, Acceleration, Deceleration or Jerk) compared to the previous request (see example interconnection).
Evaluation/recommendations:
The described behaviour can be avoided by means of the above-described remedy.
