7.2.1.218 PositionerCorrectorPIDDualFFVoltageGet
Name
PositionerCorrectorPIDDualFFVoltageGet – Gets PIDDualFFVoltage 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 dual feed-forward
with a motor voltage output.
NOTE
The “CorrectorType” must be “PIDDualFFVoltage” in the stages.ini file. This
servo loop type is used when the position servo loop drives the voltage applied
directly to the motor.
