Values in both columns must be considered simultaneously.
The following figure provides the maximum permissible radial vibration velocity including the
vibration amplitude and vibration acceleration:
The measuring equipment for measuring the vibration velocity must fulfill the requirements
of ISO 2954. The vibration acceleration must be measured as a peak value within the time
period based on a frequency band of 10 Hz to 2000 Hz.
If appreciable vibration excitation at a frequency of over 2000 Hz, for example, gear teeth
meshing frequency, can be expected, the measurement range must be adapted accordingly.
This does not alter the maximum permissible vibration values.
Note
Avoiding continuous operations at natural frequencies
Uninterrupted duty at natural frequencies of the installed/mounted system should be
avoided, as this generally leads to the permissible vibration values being exceeded and the
system being damaged. To reduce vibration, you are recommended to support flanged-
mounted motors at the NDE.
Note
Measuring vibration values according to the relevant directives
Vibration must be analyzed and measured, for example, measuring points, according to
ISO 10816-3.
