PositionerCorrectorPIDFFVelocitySet

Name
PositionerCorrectorPIDFFVelocitySet – Sets PIDFFVelocity corrector parameters.
Input tests
- Refer to section 7.1: "Input Tests Common to all XPS Functions".
- Checks the positioner type and the corrector type: (-8)
- Checks parameter value: (-17)

Description
This function configures the "PIDFFVelocity" corrector parameters.
The "CorrectorType" parameter must be defined as "PIDFFVelocity" in the
stages.ini file else (-8) error is returned. This servo loop type is used when a
constant value applied to the driver results in a constant velocity of the stage.
