3.9 Vibrational behavior
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 in󹪞uenced 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 speci󹪝ed 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 ful󹪝ll 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 speci󹪝ed limits at any measuring location.
