8.1.7 Vibration response
Vibration severity grade
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
N
).

Figure 8-1 Vibration severity levels
Permissible vibration in operation
In order to guarantee the proper function of the motor and not to impair the lifetime of the
bearing, the following vibration values must be observed during operation.
● Vibration velocity
1)
V
rms
according to ISO 10816 Max. 4.5 mm/s
● Vibration acceleration a
peak
axial
2)
50 m/s

1)
To measure the vibration velocity, the measuring equipment must fulfill the requirements of ISO 2954.
2)
The vibration acceleration is evaluated in the frequency range of 10 Hz to 2000 Hz.
The maximum peak in the time range is considered.
