摘要:
In one embodiment, a motor drive is provided that includes a control board and one or more option boards coupled to the control board via one or more serial interfaces such that data from the one or more option boards is communicated via one or more synchronous interrupts on the one or more serial interfaces. A method of operating a motor drive that includes transmitting one or more signals from an option board to a control board via one or more synchronous interrupts, wherein the option board is coupled to the control board via a serial interface. A tangible machine-readable medium implementing the method is also provided.

A power electronics device with an improved human interface module (HIM) is provided. More specifically, a motor drive is provided that includes a HIM with a portable memory device that stores the programming configuration of the motor drive. The improved HIM with portable memory enables improved techniques for quickly and efficiently updating the programming configuration of one or several motor drives.

An industrial control system includes a motor drive, a wireless interface module, and a wireless user interface. The motor drive has at least a first port. The wireless interface module is coupled to the first port of the motor drive. The wireless user interface is operable to connect to the wireless interface module and establish a first connection through the wireless interface module to access the motor drive. A user interface operable to connect to a device within an industrial control system includes a display and a processing unit operable to establish a connection with the device and display an image representative of the device on the display responsive to establishing the connection.

A method and apparatus used with a motor controller having a PWM inverter for eliminating discontinuities in a stator current that are caused by noise, command signal discontinuities and feedback corrections. While noise, discontinuities, and correction can cause multiple crossings between a carrier signal and a command signal during a half cycle of a carrier signal, the present invention only allows a single crossing during any carrier signal half cycle to effect motor operation.
