8-1-4 Wiring
This section provides examples of connections to motor drives. Refer to the specifications for the motor
drive being used before actually connecting a motor drive.
The cable length between the Pulse I/O Module and motor drive 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 VDC or 5 VDC) with any other I/O applications.
