Wiring of Connectors for External Devices

This section describes how to wire the high-speed counter module with an encoder or a controller.
6.6.1

Wiring precautions

To obtain the maximum performance from the functions of the high-speed counter module and improve the system
reliability, an external wiring with high durability against noise is required.
Precautions for the external wiring are as follows.
(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, always 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 high-speed
counter module connectors and securely tighten the two screws.
• When disconnecting the cable from the high-speed counter module, 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 supply
• Each DC power supply to be connected to the high-speed counter module, encoder, and controller must be
connected to a different power supply.
