The specified maximum radial and axial vibration values must be adhered to at the same time. They
apply to substructures which can be described as elastic. An elastic substructure is present if the
lowest natural frequency of the overall system (machine and base) in the measuring direction is at
least 25% below the essential excitation frequency. All of the other substructures can be described as
rigid. In case of rigid substructures, the manufacturer must be consulted.
Maximum radial vibration load:
Peak vibration acceleration
1 g
> 250 Hz
Peak vibration displacement
≤ 0.16 mm
< 6,3 Hz
Effect. vibration speed
≤ 4.5 mm/s
6.3 Hz
– 250 Hz

Maximum axial vibration load:
Peak vibration acceleration

The specified vibrations are additionally endured by the motor. However, the service life of wear parts
(such as bearings) can be reduced.
Shock load:
If there are increased vibration loads in the form of shocks, measurements on the installed machine
are necessary.
Based on this, constructive revisions and evaluations are carried out with the company Baumüller.
To evaluate the vibration speed, the measuring equipment shall meet the requirements of ISO 2954.
The vibration acceleration shall be evaluated in the time range in the frequency band from 10 Hz to 2
kHz.
If significant vibration excitations above 2 kHz are to be expected, such as meshing frequencies, the
measuring range must be adapted accordingly. The permissible maximum values thereby do not
change.
