6.2 External Wiring
This section describes wiring of encoders and controllers to the flexible high-speed I/O control module.
External wiring precautions
To obtain the maximum performance from the functions of the flexible high-speed I/O control module and improve the system
reliability, an external wiring with high durability against noise is required.
This section describes the precautions for wiring of encoders and controllers.
Wiring
• Different terminals are prepared depending on the voltage of the signal to be input. Connecting to a terminal with an
incorrect voltage may cause a malfunction of the module or failure of the connected devices.
• In 1-phase pulse input, always connect a pulse input cable on the phase A side.
• Install a fuse for each external terminal to prevent the external devices or module from being burnt out or damaged if a load
shorts in an output circuit. The following fuses have been tested by Mitsubishi.
Connector for external devices
• Connectors for external devices must be soldered or crimped properly. A poor soldering or crimping may result in a
malfunction.
• Securely connect the connectors for external devices to the connectors of the flexible high-speed I/O control module, and
securely tighten the two screws.
• When disconnecting a cable from the flexible high-speed I/O control module, do not pull the cable holding the cable part.
Remove a cable supporting the connector part of the cable by hand. Pulling the cable being connected to the flexible high-
speed I/O control module can cause a malfunction. In addition, a damage of the flexible high-speed I/O control module or
cables can result.
