Communication operation

Using the PU connector enables communication operation from a personal computer, etc. When the PU connector is used for
connection between the converter and a personal, FA, or other computer with a communication cable, a user program can run
to monitor the converter or read and write parameters.
Communication with the Mitsubishi inverter protocol (computer link operation) can be performed.
(For the details, refer to
page
CC-Link communication can also be performed when a communication option (FR-A8NC) is installed on the converter.
Installation of the FR-A8NC
• To install the FR-A8NC, the enclosed earthing (grounding) cable is required. Follow this procedure to install the FR-A8NC.
Step
1
Insert spacers into the mounting holes that will not be tightened with the option mounting screws.
2
Fit the connector on the FR-A8NC to the guide of the connector on the converter, and insert it as far as it goes.
Secure the one terminal of earthing (grounding) cable to the left top mounting hole on the converter with the mounting screw of the
3
FR-A8NC (tightening torque: 0.33 to 0.40 N·m).
Fix the right top side part of the FR-A8NC securely to the converter with the mounting screw of the FR-A8NC. Place another
terminal of the earthing (grounding) cable on the left bottom mounting hole in the FR-A8NC, and secure the cable terminal and the
4
FR-A8NC to the converter with the mounting screw of the FR-A8NC (tightening torque: 0.33 to 0.40 N·m). If the screw holes do not
line up, the connector may not be inserted deep enough. Check the connector.

NOTE
• When the FR-A8NC is installed, it is difficult to check the operation status 7-segment LED display on the converter.
• Affix the communication option LED label on the control
circuit terminal block cover so that small holes in the label
can be aligned with the communication operation status
inspection ports on the cover.
• Lead the CC-Link cable to the outside of the converter through the side of the
control circuit terminal block cover. Use a nipper or the like to cut the side of
the control circuit terminal block cover. Finish the cut surface without leaving
rough edges.
