Coarse-Resolution Position Encoders
Axes with coarse-resolution position encoders are known to have sharp discontinuities or step changes in their position feedback. If you can see the Position Feedback signal of an axis moving between discrete values when the axis is disabled, then it is very possible that the axis has a coarse-resolution position encoder.
When Automation1 Studio measures the frequency responses of axes with coarse-resolution position encoders, the results frequently contain invalid data points. These invalid data points are caused by encoder data that is not sufficient. In the Frequency Response module, the Enable Motion feature can make the quality of frequency response measurements much better on axes that have low-resolution encoders.
