Please read our Legal Disclaimer before executing any steps on this article.

Overview

This procedure is used when wanting to change from Internal Power Supply for I/O or External Power Supply. DENSO robot c RC9-M and RC9-L are setup for Internal Power when shipped from the factory.

Tools and Parts Needed

- Hex Key. (to remove cover)

- Soldering Equipment (for User Power I/O rewiring)

- Safety Gear

Note:
If you are not sure which part number you need or the Robot Arm you own please stop and contact your DENSO Robotics sales representative.

Step by Step Guide

Step 1 Remove RC9 front cover plate.	https://www.fa-manuals.denso-wave.com/en/RC9/010563/
Step 2 Locate the 2 dongles in the picture. (Factory Set for Internal power)
Step 2.1 - Using Internal I/O Power The DB9 dongle comes setup for Internal power. If both are plugged in then the controller is ready to be use with Internal power from the factory. https://www.fa-manuals.denso-wave.com/en/RC9/018175/ The following steps are only when wanting to change to External Power Supply.
Step 3 - Using External I/O Power If external power is needed you will need to reconfigure pins inside D-sub connector. See Below: https://www.fa-manuals.denso-wave.com/en/RC9/018175/
Step 4 - Disassembling of the User Power Internal Power Source Connector Place the User Power internal power source connector so that the screw heads are visible, as the following figure shows.
Step 5 Remove two screws shown in the STEP1, remove the upper hood.
Step 6 Remove two of cable clamp fixing screws, and remove the cable clamp and the cable sleeve.
Step 7 Remove the D-sub connector part.
Step 8 - Wiring for the Use of External Power Source Remove already soldered wires (wirings that short-circuit No.2-No.6 pins and No.4-No.7 pins). As the soldered parts are covered with a heat shrink tube, remove the tube and then melt the soldering to remove the wires.
Step 9 Pass the cables connecting to the power source and an external device through the cable sleeve.
Step 10 Solder cable lines connecting to the power source and an external device to the No.6 and No.7 pins of the User Power internal power source connector. If necessary, insulate soldering parts with a heat shrink tube. The following figure shows the terminal number of the User Power internal power source connector, viewed from the soldering part.
Step 11 With the reverse process of the disassembly of the User Power internal power source connector, assemble the connector. The wiring of the User Power internal power source connector completes.
