9.1.3 Vibration
Vibrations are sine-wave oscillations in stationary use, which vary in their ef‐
fect on the resistance of the motors depending on their intensity.
The specified limit values are valid for frequencies of 10‑2,000 Hz during
stimulation on the motor flange. Limitations can be necessary for occuring
resonances depending from the application and installation situation.
