3 Continue moving the encoder slowly between the limits of motion until a few full limit-to-limit mo-
tions have been completed.
NOTE
The wave shape can include imperfections that won’t affect the accuracy of measure-
ments. However, erratic frequency or amplitude variations or high noise content can
cause inaccuracies. If any erratic 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 com-
pleted without 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 when the encoder is moved
slowly between the limits of motion. Move the encoder and evaluate the resulting pat-
tern.
