6.7 Permissible motor vibrations
The following effects can increase motor vibration values:
● The on-site system vibration characteristics depend on factors such as the output
elements, mounting conditions, alignment and installation
● Effects of external vibrations
Ensure that the vibration values conform to project specifications and the following tables are
not exceeded at the specified measuring points on the motor.
Observe the notes for measuring points, measurement and evaluation according to ISO
10816.
If necessary, balance the rotor with the drive system completely.
