This section describes wiring of encoders and controllers to the high-speed counter module.

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.
Here are some precautions when wiring encoders and controllers.

• Different 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 or failure of the connected devices.

• In 1-phase input, always connect a pulse input cable on the A-phase 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.

• Connectors for external devices must be soldered or crimped properly. A poor soldering or crimping may 

result in malfunction.

• Securely connect the connectors for external devices to the connectors of the high-speed counter module, 

and securely tighten the two screws.

• When removing a cable from the high-speed counter module, do not pull the cable by the cable part.  

Remove a cable supporting the connector part of the cable by hand. Pulling the cable being connected to the 
high-speed counter module can cause malfunction. In addition, a damage of the high-speed counter module 
or cables can result.
