It is possible that the Motor Driver modules both in the Drive Unit and the
Switching Power Supply can become very hot. If you maintain these units,
examine the surface temperature, and wear protective gloves if necessary.
Do not remove any parts that are not covered in this manual. Follow the
maintenance procedure strictly as described in this manual. When you do
replace a part or maintain the equipment, do not proceed in any other ways than
described in this manual.
Do not shock, shake or drop the HDD, FDD and CD-ROM drive. When these
disk drives are shocked physically, it may damage the contained data.
Make sure that the wattage of the new Motor Drive module is correct. When
the inappropriate wattage module is connected with the Drive Unit, the robot
may not function properly or may be damaged.
Check on the Connection Check Label, DU number (at Control Unit) and
Signature Labels (at Drive Unit & Manipulator) when connecting those units.
If those units are misconnected, the robot may not function properly or may be
damaged.
If there are more than one Drive Units connected to the Control Unit, make sure
that the DU numbers (DU1−DU3) indicated at the Control Unit (above the MIB
connector) and the Drive Unit (above the MOTION connector) match. It is
highly dangerous if those do not match, causing to activate an unintended robot.
