3.3.2 Set up the SCARA robot
RH-1FRHR5515
The table below shows how to set up and fix the SCARA robot RH-1FRHR5515.
The base area of the robot arm has been levelled by machine.
If the base area is too uneven then this may result in robot arm malfunctions.
Fix the robot arm above the assembly boreholes on the four outer edges of the base area using
the supplied Allen head screws.
Align the robot arm horizontally.
The average surface finish of the assembly surface should be Ra = 6.3 μm. If the surface is too
rough then this may result in deviations in the position of the robot arm.
To avoid position deviations, the peripheral equipment that the robot accesses as well as the robot
arm itself should be installed on a common assembly platform/area.
The base area must be designed so that no distortion can occur, even from the loads and
vibrations emanating from the robot itself.
Only remove the transportation tool and the transport locks after setting up the robot arm.
High loads and strains occur on the base area when operating the robot at high speeds. Make
sure that the base area is suitable for the high forces and moments, as listed in Tab. 3-4.

CAUTION:
●
When installing the robot, make sure that there is enough space remaining at the rear of the
robot arm to connect the cable used and to replace the backup battery.
●
And don't install the robot arm in the position where direct rays or the heat of lighting hits.
The skin temperature of the robot arm may rise, and the error may occur.
