Rexroth IndraDyn A Application Notes
9-3
Shock
The shock load of the motors is indicated by providing the maximum
permitted acceleration in non-stationary use, e.g. during transport.
Prevent damage to the motor by avoiding shocks which exceed the
provided limits.
Based on DIN EN 60721-3-3 (1995), the following values apply for
IndraDyn A motors:
Maximum permissible shock load
(duration 11ms)
Motor frame size axial radial
100 .... 180 10 m/s² 150 m/s²
Fig. 9-4: Maximum values for shock load
Note:
Please also observe the specifications in Chapter 10.4
“Transportation and Storage”.
The construction and effectiveness of shock-absorbing or shock-
decoupling attachments depends on the application and must be
determined using measurements. This does not lie within the area of
responsibility of the motor manufacturer. Modifications to the motor result
in nullification of the warranty.
9.4 Compatibility with Foreign Material
All Rexroth drive-and-control devices are developed and tested according
to the state-of-the-art.
However, as it is impossible to follow the continual development of all
material which may come into contact with our drives and controllers, e.g.
lubricants for machine tools, we cannot, in general, exclude any reaction
with the materials used in our systems.
For this reason, you will have to carry out a test of compatibility between
new coolants, lubricants, detergents, etc. and our housing/our housing
materials.
