pass filter parameters.
Input tests
- Refer to section 7.1: “Input Tests Common to all XPS Functions”.
- Checks the object type of this command is valid: (-8)
- Checks input parameters value: (-17)
• CutOffFrequency with CorrectorPeriod = 0.0001 s (10 kHz) = >
- Checks the positioner name: (-18)
- Checks compensation post excitation mode is enabled: (-24)
- Checks the motion status (Motion status must be disable): (-134)
