AD5430-11

　 Ad5430-11 (6 Axis encoder board)

　Features

　This is an encoder input board with pulse output. It can be used to controls stepper and servo motor positioning (pulse train input type).

One board can provide input/out for 6 axes.
The encoder input consists of 3 signals for A, B, and Z phases for each axis. The encoder input circuit has a differential line driver connection.
The output gives two pulses for each axis. It is assumed to be controlling a stepper or servo motor driver (pulse train input system). Pulses are output through a differential line driver.
