Newport XPS-D - Positionerhardinterpolatorfactorset

XPS Unified Programmer’s Manual
7.2.1.257 PositionerHardInterpolatorFactorSet
Name
PositionerHardInterpolatorFactorSet – Sets the interpolation factor for position
compare mode.
Input tests
- Refer to section 7.1: “Input Tests Common to all XPS Functions”.
- Checks the positioner type (must be not a secondary positioner): (-8)
- Checks the encoder type (must be “AnalogInterpolated”): (-8)
- Checks input parameter value: (-17)
- Checks the positioner name: (-18)
- Checks the group state (must be NOTINIT): (-22)
Description
This function sets the interpolation factor of the hardware interpolator used in the
“PositionCompare” mode. The IP200 is updated and the position compare resolution is
set as follows:
PositionCompareResolution = EncoderScalePitch/InterpolationFactor
The “InterpolationFactor“ value must be define with one of these values:
20 25 40 50 80 100 160 200
If the input interpolator factor value is different from these values then (-17) error is
returned.
NOTE
The group must be NOTINIT to use this function else (-22) error is returned.
The encoder type must be “AnalogInterpolated” in the stages.ini file
(“EncoderType” parameter) else the error is returned.
This function applies to XPS-Q hardware. It is kept for XPS-D and XPS-RL
backward compatibility but has no effect.
