PositionerCompensationSpatialPeriodicNotchsGet

Name
PositionerCompensationSpatialPeriodicNotchsGet – Gets pre-feedforward
compensation spatial periodic filters parameters.
Input tests
- Refer to section 7.1: "Input Tests Common to all XPS Functions".
- Checks corrector type: (-8)
Description
This functions returns the CompensationSystemPreFeedForward spatial periodic filters
parameters. These filters reduce the spatial periodic perturbations coming from screw
pitch or cogging.
Note that the CompensationSystemPreFeedForward feature is available for all corrector
types (acceleration, velocity, voltage or position) functioning in closed loop
configuration.
