NOTE
Select Pseudo-Sinusoidal if your TTL encoder output waveshape
is degraded by the capacitive characteristics of its cable/wiring.
4 Repeat step 3 for the remaining axes.
Proceed to the next section to calibrate analog encoders. TTL encoders require
no further action.
Calibrating analog encoders
Analog encoders require calibration. The process of calibrating analog encoders
is very straightforward and is identical for current and voltage output devices.
To calibrate an analog encoder:
1 Select the desired axis,
confirm that the correct Axis
Scale Type is selected and click
the Wave Display Type.
2 Click the Calibrate button. You will be instructed to move the axis. Begin
moving the axis in slow, gradual back and forth or up and down motions, and
click OK. The sinewave output of the analog encoder will be displayed as the
axis is moved. The display is shown as two sinewaves that are 90 degrees out of
phase. The real-time display changes as the encoder is moved, however, still
images can be captured for evaluation at any time by clicking the Freeze button.
Clicking the Display button reverts to the real-time
display.
After a moment the Custom Encoder Setup window will also be displayed and
will show the changing output count value and the number of count errors
detected since the calibration began.
