Encoder quadrature signals and pulses

Question

How does Gocator read encoder quadrature signals and/or pulses?

Answer

Gocator reads the rising edge of each of the four encoder quadrature signals (A+ / A- / B+ / B-). However, encoders are typically specified by pulses per revolution, where a pulse represents a full set of the four quadrature signals. You should therefore keep this in mind when choosing an encoder, given the resolution required for your application.

NOTE: In the Gocator web interface, on the Manage page, in Motion and Alignment, encoder resolution is specified as "mm/tick," where one "tick" corresponds to one of the four quadrature signals.
