DGEA-...
Optimizing the vibration behaviour on the
DGEA-...:
5. Place the mass centre of gravity of the
work load centrally to the cantilever arm.
If fitted correctly, distance "a" remains
small (see Fig. 11).
Definition
Work mass =
In ascertaining the loading by means of a
formula, the following should be calcu-
lated:
In the mass moment of inertia of the work
mass (J ), related to the mass moment of
A
inertia of the motor (J
the Catalogue "Products ...").
Formula:

(I = gear ratio
n /n
motor axis
Fastening the accessories:
6. Use the grooves ( 2 ).
By means of a recess, sliding blocks which
cannot be clipped in as desired, slide into
the relevant groove.
7. Make sure that the DGEA-... is driven only
by one of the following types of motors:
Only these types match each other.
