5-1 Installation base

WARNING

If the installation base is not sufficiently rigid and stable, vibration (reso- nance) may occur during operation and adversely affect the robot work. In worst cases the robot might even fall over causing a serious accident.

!CAUTION

If the installation surface accuracy is insufficient, the robot positioning accuracy and machine life may drop, and noise may be generated.

1)Select an installation base that has sufficient rigidity and stability to with- stand the robot (including tool) and workpiece weight and the reaction gen- erated during operation.

2)The installation base surface must be machined to a flatness within ±0.05mm/ 500mm.

3)If there is a clearance between the installation base and robot frame when the robot is set on the base, insert suitably thick shims in the clearance to prevent stress from being applied on the robot frame.

4)Avoid fixing the robot onto the installation base with less than the specified number of bolts, or installing only one end of the robot. Failure to observe this could lead to an increase in robot vibration and decrease in positioning accuracy.
