5. Precautions for Use
The robot comes with a 24-pin plug (NJW-28-24-PM-18 manufactured by Nanaboshi Electric Mfg.) to be
connected to the user connector.
Solder the cable provided by the user to the connector (plug) and connect to the user connector. Use a
shielded cable with an outer diameter of
I16.1 to I18.0.
Pins 1 to 23 of the connector can be used. Pin 24 is connected to the shielded cable.
How to wire the connector
[1] As shown above, disassemble the connector, pass the cable, and solder the cable to the contacts.
[2] Use a tester, etc., to confirm that the specified pins are electrically connected to the cable.
[3] Screw the barrel into the end bell and affix with setscrew A.
[4] Push the cable gasket and washer into the end bell, hold the end bell in place, and screw in the clamp
nut.
[5] Move the cable back and forth and to right and left until the cable moves smoothly. Tighten all parts to
the specified torques again, and then tighten setscrew B.
z Before commencing wiring/piping work, turn off the power to the controller and the power/air
supplies to the robot. Failure to do so may cause the robot to malfunction.
z Use cables and tubes within their specifications. Failure to do so may result in fire due to an
overheated cable, or may cause current or air leaks.
z Connect the shielded cable to the hood. Otherwise, the robot may malfunction due to noise.
z If the user connector is not used, attach a cap on the opening. Otherwise, water or powder dust will
enter through the opening.
z Tighten each connector screw to the specified torque.
z If the outer diameter of the cable is smaller than the specified size, wrap a tape, etc., around the
cable clamp to increase the clamp size.
