The noise values are valid when the motor is fed from the SIMODRIVE 611
PWM inverter for non–ventilated and separately–ventilated motors (with the
exception of shaft height 132), measured at 1 m.

The specified values refer to the motor alone. The system vibration characteris-
tics, as a result of the mounting type, can increase these values at the motor.
The speeds of 1800 RPM and 3600 RPM and the associated limit values are
defined acc. to IEC 34–14. The speeds of 4500 RPM and 6000 RPM and the
specified values are defined by the motor manufacturer.
