US 9,071,189 B2 · Motor drive configuration system and method

Abstract

A motor drive comprises a power sub-assembly and a control sub-assembly removably secured to the power sub-assembly. The power sub-assembly contains all power electronic circuitry and driver circuitry for the power electronics. The control sub-assembly comprises control circuitry for implementing a motor control routine that generates control signals for the power sub-assembly. The control sub-assembly is configured to conform to a USB mass storage device class such that it will appear as an icon on a configuration station when coupled to the configuration station via a USB cable. Thereafter, the drive may be accessed by selecting the icon, and parameter file and data transfer may be performed, such as by drag-and-drop transfer steps.

Dependent claims

A motor drive system comprising:

a power subassembly including power electronic switches controllable to provide controlled frequency AC power to an electric motor, and driver circuitry configured to apply gate drive signals to the power electronic switches;
and
a control subassembly separable from the power subassembly but physically configured to be attached to the power subassembly and to make electrical connections with the power subassembly when attached, the control subassembly including control circuitry configured that, in operation, applies control signals to the drive circuitry for controlling the power electronic switches, the control subassembly being configured to be coupled to a configuration station and comprising an interface that identifies the motor drive system to the configuration station in conformance with a USB mass storage device class.

Dependencies are inferred from the claim text.
