Programming D-61
DC590+ Series DC Digital Drive
ENCODER TYPE = QUADRATURE
A quadrature encoder uses 2 input signals (A and B), phase shifted by a quarter of a cycle (90).
Digital input 2, (C7) = Encoder A phase
Digital input 3, (C8) = Encoder B phase
Direction is obtained by looking at the combined state of A and B.
Each edge received from the encoder increments the encoder count. There are 4 counts per line.
Speed is calculated using the following function:
