Affixing the Load to the L-738 / V-738 

 

NOTICE 

 

Impermissibly high load on the stage! 

An impermissible high load impairs the motion of the motion platform and can damage the 

stage. 

 

When considering the mass and mounting method of the load, pay attention to the 

specified maximum permissible forces, that are permitted to act on the motion platform 

(p. 37). 

Requirements 

 

You have read and understood the general notes on installation (p. 17). 

 

You have mounted the stage properly onto a surface (p. 19). 

 

The stage is 

not

 connected to the controller. 

 

You have prepared the load so that it can be affixed to the mounting holes on the 

motion platform: 

−

 

The distance between the center of gravity of the load and the center of the motion 

platform is as small as possible in all directions. 

−

 

At least two points are provided for affixing the load to the motion platform 

(ideally: three attachment points). 

Tools and accessories 

 

At least 2 M6 screws of suitable length  

 

Suitable tool for tightening the screws. 

 

Optional: Dowel pins, ISO 8734 - 6 m6 x 16 (locating pins) 

Affixing the load 

1.

 

If you use locating pins for aligning the load: Insert the locating pins into the holes 

provided in the motion platform. 

2.

 

Align the load so that the selected mounting holes in the motion platform can be used 

to affix it.  

3.

 

Use the screws to affix the load to the selected mounting holes in the motion platform. 

4.

 

Check that the load is affixed firmly to the motion platform of the stage.
