Abstract
The present invention is directed at a method for operating rotating machinery, such as an electric motor, by means of a variable speed drive (VSD). The variable speed drive is provided for identifying mechanical resonance points by means of a sensor and corresponding speeds of the machinery; storing the speeds at which the identified mechanical resonance points occur; and bypassing the speeds at which the identified mechanical resonance points occur during operation of the rotating machinery. The invention is also directed at a variable speed drive for performing said method.
