5.6 Vibration response

5.6 Vibration response
Vibration severity grade
Motors with keyway are balanced by the manufacturer using a half-key.
The vibration response of the system at the location of use is influenced by output elements, any
built-on parts, the alignment, the installation, and external vibrations. This can change the
vibration values of the motor.
The motors conform to vibration severity grade A according to EN 60034-14 (IEC 60034-14).
The specified values refer only to the motor. The installation-dependent system vibration
behavior can increase these values at the motor.
The vibration severity grade is maintained up to the rated speed (n

The measuring equipment must fulfill the requirements of ISO 2954 to evaluate the vibration
velocity
Select the measuring locations according to ISO 10816-1, Section 3.2.
The vibration acceleration is evaluated in the frequency range from 10 Hz ... 2000 Hz. The
maximum peak in the measurement time range is taken into consideration.
The vibration values must not exceed the specified limits at any measuring location.
