5.4 Wiring
This section describes how to wire the QD65PD2 with an encoder or a controller.
5.4.1 Wiring precautions
To maximize the functions of the QD65PD2 and ensure high-reliability of the system, external wiring that is less
susceptible to noise is required.
Observe the following precautions for the external wiring.
(1) Wiring
• Terminals are prepared depending on the voltage of the signal to be input. Connecting to a terminal with a
different voltage may cause malfunction of the module and failure of the connected devices.
• In 1-phase input, be sure to connect a pulse input cable to the A-phase side.
(2) Connectors for external devices
• Securely connect the connectors for external devices (A6CON1/A6CON2/A6CON4 to the QD65PD2
connectors and securely tighten the two screws.
• When disconnecting the cable from the QD65PD2, do not pull the cable by the cable part. Hold the
connector part of the cable. Pulling the cable connected to the module may result in malfunction or damage
to the module or cable.
(3) DC power
• Each DC power to be connected to the QD65PD2, encoder, and controller should be connected to a
different power supply.
