1) Click the 'Calibrate' button on the Encoder control panel (or call the CalibrateEnc method).
The 'Encoder Control Panel' closes and the system begins the calibration sequence by first homing the channel and then
moving through a series of user defined microstep position points taking the encoder reading at each. This process can take
several minutes.
Once a calibration table has been acquired it can be enabled by clicking the 'Use Calibration Table' checkbox.
Note
The ‘Use Calibration Table’ checkbox is not enabled automatically and must be
enabled in the 'Encoder Control Panel'.
It is not compulsory to use the calibration data (i.e. checking the 'Use Calibration
Tabel’ checkbox), however this is advisable if best system performance when using
encoder equipped stages is to be obtained.
The encoder calibration table is used to generate the calibrated positions values
returned by the GetPositionEx method when in 'Encoder Positioning' mode.
When in encoder positioning mode, the encoder calibration table overrides any other
calibration table associated with the particular motor channel using the APT Config
utility.
