L_TT1P_ElectricalShaftPosHigh: The programmed path parameters are exceeded during the offset procedure (corrected from V3.22.0)

Corrected from:

Library: L_TT1P_TechnologyModules_LM from V3.22.0.19

(Update via EASY Package-Manager)

Response of the new version:

The offset between master and slave axis via the lrOffset input is moved out via the defined path parameters (lrOffsetSlaveAccDec, lrOffsetSlaveVelPos, lrOffsetSlaveVelNeg).

What happens?

When extending the offset (via TM input lrSetOffsetSlave) the path parameters are exceeded.

When does the behaviour occur?

If the gear ratio dwNumerator / dwDenominator is not equal to 1, the path parameters (lrOffsetSlaveAccDec, lrOffsetSlaveVelPos, lrOffsetSlaveVelNeg) for moving the offset are exceeded.

Which products are affected?

Function block L_TT1P_ElectricalShaftPosHigh from library L_TT1P_TechnologyModules_LM (from V3.16.0)

Short-term measures:

The trajectory parameters (lrOffsetSlaveAccDec, lrOffsetSlaveVelPos, lrOffsetSlaveVelNeg) are to be taken into account with the factor (dwDenominator / dwNumerator).

Evaluation/Recommendations:

The function for the offset procedure is given. Taking into account the short-term measure, the path parameters can be designed so that the maximum values of the axis are not exceeded.
