L_MC1P: MC_MoveAbs, MC_MoveRel: Rarely occurring unsteady setpoint characteristic (corrected from V03.21.00)

Correct from:

Library: L_MC1P_MotionControlBasic (FAST Motion) from V03.21.00.102

(Update via Package-Manager)

Response of the new version:

When generating the reference values during positioning, the described discontinuities no longer occur.

What happens?

During an ongoing positioning process, discontinuities occur in the generated target values for speed and acceleration. These have a corresponding effect on the drive behavior.

When does the behaviour occur?

MC_MoveAbsolute, MC_MoveRelative, MC_MoveContinuousAbsolute, MC_MoveContinuousRelative, MC_MoveAdditive, MC_MoveSuperimposed L_MC1P_AxisBasicControl, L_MC1P_AxisBasicControlV2:

This behavior rarely occurs if:

when the distance to be moved is small,
if the maximum values set at the FB inputs Velocity, Acceleration and Deceleration cannot be reached during positioning and
at least one of these maximum values is just about reached by the corresponding setpoint.

Which products are affected?

Library: L_MC1P_MotionControlBasic (FAST Motion)

Short-term measures, Evaluation/Recommendations:

Set the maximum values at the FB inputs Velocity, Acceleration and Deceleration so that they can be reached.
