Speed feedforward control in cyclic systems (Modulo) (remedied from V1.5)

Which products are affected?
9400 HighLine SW V1.5

Corrected function restriction
In the LS_PositionFollower basic function, the differentiation of the position via C02681 was incorrect in Modulo mode.
This error has been corrected.



Which products are affected?
9400 HighLine SW ≤ V1.37

What happens?
During the activation/use of the basic functions of the MotionControlKernels (MCK), e. g. during homing, manual jogging and positioning, the input speed is limited to the reference value in code C00011. The reference value is not displayed for the user in application units (units), even though the basic functions operate with a reference to application units.

When does the problem occur?
Traversing of the drive via the basic functions

Possible diagnostics?
Comparison of the current speed of the drive with the values in the codes C00051 and C00011.

Short-term measures/recommendations?
Note the setting for the reference speed C00011 during commissioning.

Evaluation
The restriction has no functional impact on the application. The behaviour needs to be taken into account by the user.
