3 Continue moving the encoder slowly between the limits of motion until a
few full limit-to-limit motions have been completed.
NOTE
The waveshape can include imperfections that won’t affect the
accuracy of measurements. However, irratic frequency or
amplitude variations or high noise content can cause
inaccuracies. If any irratic output is noted, or if scale errors
appear, check the encoder head mounting, alignment and wiring
for problems.
4 When a few full limit-to-limit
motions have been completed with-
out scale errors, click OK to close the
Custom Encoder Setup window and
proceed to the next
step.
The display of scale
and error counts can
be recalled at any
time by clicking the Counter button.
5 Select the Phase Display Type to display the combined
phases of the encoder output as an ellipsoidal pattern in the
Custom Encoder Setup window as the encoder is moved slowly
between the limits of motion. Move the encoder and evalu-
ate the resulting pattern.
