Vibration Severity - Siemens SIMOTICS M-1PH8 Operating Instructions & Installation Instructions

If you are not familiar with the prescribed measures and procedures, then you can make use
of the services offered by the local Service Center (Page 123).

Vibration severity

Due to the influencing variables listed below, the vibration response of the system at the site
of operation can lead to increased vibration severity at the motor:
● Transmission elements
● Assembly conditions
● Alignment and installation
● Effects of external vibrations
Under certain circumstances, the rotor may have to be balanced completely with the output
element.
Please take care to ensure that the vibration severity specified to ISO 10816 is not exceeded
at the defined measuring points on the motor. By doing this, you can ensure problem-free
operation and a long service life.
Maximum permitted vibration severity
The values for the maximum permitted radial and axial vibration severity must both be
maintained.
