AC890PX AC Drive
Functional Description
A quadrature encoder uses 2 input signals (A and B), phase shifted by a quarter of a cycle (90
°
). Direction is obtained by looking at the combined
state of A and B.
A
B
Speed is calculated using the following function:
SPEED HZ =
Counts Per Second
Lines x 4
where counts per second are the number of edges received from the encoder. There are 4 counts per line.
