Design and Installation Safety

The robot system should be designed and installed by people who have received installation training provided by Epson and the suppliers.
Design personnel should refer to the following manuals:
"Safety Manual"
"Controller Manual"
"Manipulator Manual"

Refer to the following section for the installation safety information.
Environment and Installation
Be sure to read this section and follow the safety information before installation to ensure that the installation work is performed safely.

Strength of the Ball Screw Spline

If a load exceeding the allowable bending load is applied to the ball screw spline, it may not work properly due to deformation or breakage of the shaft.
If a load exceeding the allowable value is applied to the ball screw spline, the ball screw spline unit must be replaced.
The allowable load varies depending on the distance over which the load is applied. To calculate the allowable load, refer to the formula below.

Allowable bending moment
GX10-B/GX10-C/GX20-B/GX20-C: M=50,000 N·mm
Calculation example: 500 N load applied at 100 mm from the end of the spline nut

Moment
M = F·L ＝ 100·500 ＝ 50,000 N·mm
