7.2.1.175 PositionerCompensationFrequencyNotchsGet
Name
PositionerCompensationFrequencyNotchsGet – Gets pre-feedforward compensation
notch filters parameters.
Input tests
- Refer to section 7.1: “Input Tests Common to all XPS Functions”.
- Checks corrector type: (-8)
Description
This function returns the CompensationSystemPreFeedForward frequency notch filters
parameters. These notch filters allow the user to reduce external perturbations such as
base motion or floor vibrations. Note that the CompensationSystemPreFeedForward
feature is available for all corrector types (acceleration, velocity, voltage or position)
functioning in closed loop configuration.
