Wiring CPU Unit I/O Section 3-5
3-5-7 Pulse Input Connection Examples
For a 24-VDC Open-
collector Encoder
This example shows the connections to an encoder with phase-A, phase-B,
and phase Z inputs.
3-5-8 Pulse Output Connection Examples
This example shows a connection to a motor driver. Always check the specifi-
cations of the motor driver before actually connecting it.
For open-collector output, use a maximum of 3 m of wiring between the CP1L
CPU Unit and the motor driver.
No pulses are output while the pulse output transistor is OFF. For a direction
output, OFF indicates that CCW output is in progress.
Do not use the same power supply for both pulse output 24-VDC/5-VDC
power and other I/O power.
