Patent ID: 7531973

Claim:
An electronic line shaft, comprising: a motor drive; and a processing unit operable to execute a wizard for configuring the motor drive, the wizard being operable to receive mechanical characteristic data associated with the motor drive that is provided as input by a wizard user, determine a noise parameter based on the mechanical characteristic data, and determine at least one control parameter of the motor drive based on the noise parameter; wherein the motor drive comprises an inertia compensation unit operable to receive a reference velocity signal, generate a derivative of the reference velocity signal, and multiply the derivative by an inertia compensation gain factor to generate an inertia compensation signal, and an adjustor operable to adjust the reference velocity signal as a function of the inertia compensation signal, and the wizard is operable to receive a system inertia parameter and determine the inertia compensation gain factor as a function of the system inertia parameter.
