PositionerEncoderCalibrationParametersGet

Name
PositionerEncoderCalibrationParametersGet – Gets the encoder calibration
parameters.
Input tests
- Refer to section 7.1: "Input Tests Common to all XPS Functions".
- Checks the positioner (must be not a secondary positioner): (-8)
- Checks the encoder type (must be "AnalogInterpolated"): (-8)
Description
After a calibration of the analog encoder input (by the function
"GroupInitializeWithEncoderCalibration"), this function returns the optimum
parameters for the analog encoder interface. To take these parameters into account
(recommended to achieve best performance), these values must be entered manually in
the corresponding section of the stages.ini file. The parameters to set in the stages.ini
file are:
• EncoderSinusOffset =
• EncoderCosinusOffset =
• EncoderDifferentialGain =
• EncoderPhaseCompensation =
The encoder type must be "AnalogInterpolated" in the stages.ini file
("EncoderType" parameter).
