Maintenance 1. Safety Precautions for Maintenance
■ Do not lose the screws removed at maintenance. When the screw is dropped
into the Control Unit or Drive Unit, be sure to take it out. Leaving the screw in
the Control Unit or Drive Unit may cause short circuit and may result in
equipment damage to the parts and/or robot system.
■ Make sure that the power rating (wattage) of a new Motor Driver module is
correct. Using a Motor Driver module with improper power rating (wattage) in
the Drive Unit may not only cause improper function of the robot system but also
damage to the system.
■ The serial numbers of the Drive Unit and Manipulator that should be connected
are indicated on the Connection Check Label on the Control Unit. Connect the
Control Unit, the Drive Unit and the Manipulator correctly.
CAUTION
connections between the Drive Unit and the Manipulator and between the
Control Unit and the Drive Unit may cause improper function of the robot system
and also safety problems.
■ If there is more than one Drive Unit connected to the Control Unit in the robot
system, make sure that the DU numbers (DU1 - DU3) indicated above the MIB
connector on the Control Unit and the Drive Unit (above the MOTION connector)
match. Improper connection between the Control Unit and the Drive Unit may
cause malfunction of the robot system and/or safety problems as it may make
the Manipulator move abnormally.
Before performing maintenance on the Controller, all the data must be copied as a backup.
NOTE
Refer to the Maintenance 2.5 Backup of Data for details.
