Siemens SIMOTICS M-1PH8 Configuration Manual

4.11 Vibration severity grade
The 1PH8 motors conform to vibration severity level A in accordance with EN60034-14
(IEC600-34-14). The values indicated refer only to the motor. The system vibration response
depends on the conditions at the installation location and can result in higher vibration values
at the motor.
Note
Vibration severity limit values
According to the vibration severity limit value diagrams below, the motors operate within the
limit values stipulated for versions R, S, SR or SPECIAL over the speci󹪝ed speed range.
Furthermore, within the rated speed range, they correspond to vibration severity grades A or B
as de󹪝ned by EN60034-14 (IEC600-34-14).
The balance quality depending on the bearing is encoded in the Article No., see Chapter
"Selection and ordering data."
As a general rule, high radial force load capacity is not compatible with high speed and
high vibration quality. The reason for this is that the di󹪜erent applications require di󹪜erent
bearings.
