3.3
Permissible motor vibration levels
System vibrations caused by output elements and mounting conditions at the installation
location can affect the vibration values on the motor.
Observe the maximum vibration values on the specified measuring points of the motor.

Measure the vibration velocity using appropriate measuring equipment.
The vibration acceleration must be evaluated in a frequency band of 10 ... 2000 Hz.
Note
If vibration excitation levels > 2000 Hz (e.g. gear teeth meshing frequencies) can be
expected, the measurement range must be adapted accordingly.
The permitted maximum values remain unchanged.
