8. Calibration
8.1 Offset Calibration
For optimal performance of the VLX-60
Electric Encoder, the inevitable DC offset
of the sine and cosine signals must be
compensated over the operational sector.
After successfully completing the Mounting
Verification procedure:
(a) Select [Calibration] on the main screen.
(b) Start the data acquisition while rotating
the shaft.
The progress bar (c) indicates the collection
progress.
Rotate the axis consistently during data
collection—covering the working sector
of the application end to end—by default
the procedure collects 500 points over 75
seconds. Rotation speed is not a parameter
during data collection. Data collection
indication shows for the fine/coarse
channels, a clear “thin” circle appears in the
center (d) (e) with some offset.
8.2 CAA Calibration
The following calibration aligns the coarse/
fine channel by collecting data from each
point of both channels.
Select [Continue to CAA Calibration]
In the CAA angle calibration window,
select the relevant option button from the
measurement range options (a):
•Full mechanical rotation – shaft
movement is over 10deg -
recommended.
•Limited section – define operation of
the shaft in a limited angle defined by
degrees in case of <10deg
•
Free sampling modes - define the number
of calibration points in the total number
of points in the text box. The system
displays the recommended number of
points by default. Collect a minimum of
nine points over the working sector.
•Click the [Start Calibration] button (b)
•The status (c) indicates the next required
operation; the shaft movement status;
the current position, and the next target
position to which the encoder should be
rotated.
•Rotate the shaft/encoder to the next
position and click the [Continue] button
(c) - the shaft should be in STAND STILL
during the data collection. Follow the
indication/interactions during the cyclic
process for positioning the shaft -->
stand still --> reading calculation.
•Repeat the above step for all defined
points. Finish (d)
•Click the [Save and Continue] button (e).
The last step saves the offsets CAA
parameters, completing the calibration
process.
