2.3.2 Installation of the robot CPU unit (CR800-Q controller)

(1) Notes on the handling

Explain notes on the handling of the CPU unit, the input/output unit, the intelligent functional unit, the power
supply unit, the base unit, etc.
1) Please do not drop the unit, the terminal stand connector, and the pin connector, or do not supply a strong
shock.
2) The printed circuit board of the unit should not remove from the case. It becomes the cause of failure.
3) Please carry out bolting of the unit fixing screw and the terminal stand screw in the range shown in
2.

4) The basic base unit should equip with the power supply unit at any cost. If the load of the input/output unit
and intelligent functional unit with which the base unit is equipped is low, it may operate, even if there is no
power supply unit. However, since voltage becomes unstable, operation cannot be guaranteed.
5) Since it may malfunction by vibration if it installs the basic base unit in the plate, please be sure to fix with
the screw for fixing.
CAUTION
CAUTION
The installation procedure of the basic base unit is shown in the following.
2-16 Installation and connection
1) Please use the robot CPU system in the environment of general specification given in
this manual. If other, it becomes the electric shock, the fire, malfunction, the damage
to the product, or the cause of deterioration.
2) Pressing down the unit lower lever for unit wearing, insert the projection for unit fixing
in the fixing hole of the base unit surely, and install with the unit fixing hole as a
fulcrum. If the unit is not installed correctly, it will become the cause of malfunction,
failure, and drop. If it uses it in the environment with much vibration, fix the unit with
the screw. Please perform bolting of the screw in the regulation torque range. If
bolting of the screw is loose, it will become the cause of drop, the short circuit, and
malfunction. If the screw is tightened too much, it will become the cause of drop by
breakage of the screw or the unit, the short circuit, and malfunction.
3) Please be sure to do the installing and removing of the unit after shutting down all
phase of the external power supply currently used by the system.
4) The installing and removing of the unit and the base may be less than 50 times after
product use. It may become the cause of malfunction if it exceeds 50 times.
5) Please do not touch the electric conduction section or electronic components of the
unit directly. It becomes malfunction of the unit, and the cause of failure.
When a CPU error occurred in the PLC, the robot CPU can operate without error.
When the robot operation is stopped when a CPU error occurred, periodically
communicate between the PLC CPU and robot CPU, and check the operating status in
robot program.
