Vibration Response - Siemens 1FK7 Series Operating Instructions Manual

Installation

5.3 Vibration response

5.3 Vibration response
Motors with a keyway are balanced with a half fitted key by the manufacturer. The vibration
response of the system at the installation location is influenced by transmission elements,
any mounted parts, the alignment, the installation, and external vibrations. As a result, the
motor's vibration values may change.
The motors conform to vibration severity grade A in accordance with EN 60034-14
(IEC 60034-14).
The specified values refer only to the motor. These values can be increased at the motor
due to the overall vibration response of the complete system after the drive has been
mounted.
The vibration severity level is maintained up to the rated speed (n
