5.5.4.1. Searching For Index
One of the advanced features of the control unit is its ability to search for the index of the encoder
at any speed. In the following example, the X motor is running at constant speed. Each time the
index is passed, the position of the index is displayed. For example, with a 2,000-line encoder
(8000 counts/rev), there should be an index pulse exactly every 8,000 counts. If a different
number of counts appears, it is a strong indication that something is wrong with the encoder
feedback path (encoder, connector, and encoder interface).
