Vibration severity
Due to the influencing variables listed below, the vibration response of the system at the
location of use can lead to increased vibration severity on the drive unit:
•
Transmission elements
• Installation conditions
• Alignment and installation
• Effects of external and internal oscillation
The vibration severity values specified in accordance with ISO 20816-1 must not be exceeded
at any point on the surface of the drive. This ensures problem-free operation and a long
service life.
Maximum permissible vibration severity
Observe the values for the maximum permissible radial and axial oscillation vibration severity
in the following table. Radial/axial refers to the motor axes.

Resonant frequencies
Resonance can occur in the speed range of the geared motor depending on the machine to
be driven.
Operation in resonance causes increased noise and vibration levels.
Adherence to the maximum permissible vibration severity is always required.
Operation in the resonant frequency leads to a reduced service life of the geared motor,
irrespective of adherence to the maximum vibration severity.
Continuous operation in the resonant frequency must be avoided.
