3-3-4 Pulse Output Connection Examples
This section provides examples of connections to motor drivers. Refer to the
specifications for the motor driver being used before actually connecting a
motor driver. With open-collector outputs, the wire length between the CJ1M
CPU Unit and motor driver must not exceed 3 m.
When the pulse output's output transistor is OFF, pulses are not being output.
When the direction output is OFF, it indicates a CCW output.
Do not share the pulse output's power supply (24 V DC or 5 V DC) with any
other I/O applications.
