How to determine the PCO encoder frequency :
-
For AquadB encoder :
PCO encoder frequency = Velocity / EncoderResolution
-
For analog interpolated encoder :
PCO encoder frequency = Velocity * HardInterpolatorFactor / EncoderScalePitch
Example: XML310 stage (EncoderScalePitch=0.004 mm,
HardInterpolatorFactor=200). With ScanVelocity=10mm/s => PCO encoder frequency
= 10*200/0.004 = 500 kHz
The function works only when the CIE08 compensated PCO mode configuration is
enabled (system.ini: CIE08CompensatedPCOMode = Enabled).
This function can be used only with a position encoder ("AquadB" or
"AnalogInterpolated"), otherwise (-24) error is returned.
