Pulse I/O Board Section 8-2
8-2-7 Wiring Examples
Pulse Input Connections Connect the encoder output to CN1 and CN2 as shown below according to
the port Input Mode.
Note The function of encoder inputs A and B in Pulse/Direction Mode and Up/Down
Mode differs from the High-speed Counter Board (CQM1H-CTB41).
Wiring Example
The example below shows connections to an encoder with phases A, B, and
Z.
