Specific APIs
In addition to the standard XPS commands, the following XPS-DRVP1 board specific
APIs are available:
-
« PositionerDriverFiltersGet » : to get axis current close loop control parameters:
KI (close loop integral coefficient), Notch filter frequency, Notch filter bandwidth,
Notch filter gain and Low Pass filter frequency
-
« PositionerDriverFiltersSet » : to set axis closed loop control parameters
-
« PositionerDriverStatusGet » : to get driver board current status number
-
« PositionerDriverStatusStringGet » : to get driver board detailed status
-
« PositionnerDriverPositionOffsetsGet »: to get offset parameters (see
Offset
