¯ The loads generated by the motor mounted must be checked!
¯ The forces F

mentioned (see following tables) at the adapter must
not be exceeded!
For the effective force F
M
, static forces (e.g. weight) and dynamic forces (e.g.
acceleration forces, for example caused by vibrations or start−up processes) have to be
taken into consideration.
Furthermore the loading case of the force F
M
has to be taken into consideration:

The position of the motor‘s centre of gravity, including all motor options, must be
calculated. If the distance of the centre of gravity L

is greater, the permissible force
must be reduced as follows.

If forces act from several directions, e.g. in the case of a moving horizontal travelling
drive, the acting forces have to be added vectorially (e.g. vertical force due to weight plus
horizontal acceleration force).
F
Mperm
corresponds to the maximum value of the forces added vectorially!

If the permissible force F

is exceeded, the motor has to be supported in a suitable,
distortion−free fashion!
