Newport XPS - Positionercorrectorpidffvelocityget

XPS Unified Programmer’s Manual
7.2.1.222 PositionerCorrectorPIDFFVelocityGet
Name
PositionerCorrectorPIDFFVelocityGet – Gets 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)
Description
This function returns the corrector parameter values used by a PID with a velocity
output:
ClosedLoopStatus, KP, KI, KD, KS, IntegrationTime,
DerivativeFilterCutOffFrequency, GKP, GKI, GKD, Kform and
FeedForwardGainVelocity.
NOTE
The “CorrectorType” must be “PIDFFVelocity” in the stages.ini file. This servo
loop type is used when a constant value applied to the driver results in a constant
velocity of the stage.
