can be found in the table "Permitted shaft loads" in this chapter.
Fig. 5: Force application points
The specified values for F
2rad100
and F
2rad,acc
refer to an application of force at the center of the output shaft: x

= l/2.
Shaft dimensions can be found in the "Dimensional drawings" chapter.

For applications with multiple axial and/or radial forces, you must add the forces as vectors.
In the event of EMERGENCY OFF operation (max. 1000 load changes), you can multiply the permitted forces
and torques for F
2ax100
, F
2rad100
and M
2k100
by a factor of two.
