    摘要: A spindle assembly includes a power source interface configured to be operably coupled to a power bus and power the spindle assembly via the power bus, a spindle controller comprising processing circuitry, a diagnostic switch assembly operably coupled to the spindle controller and operably coupled to a logic supply bus, and a working apparatus comprising a motor and a spindle operably coupled to the spindle controller. The working apparatus may be controllable by the spindle controller to act upon a work piece to perform a work task. The processing circuitry of the spindle controller may be configured to receive a fault localization instruction rom a bus control device operably coupled to the logic supply bus, and control the diagnostic switch assembly to determine a presence and a location of a fault on the logic supply bus.

    摘要: The invention provides systems, methods, and devices relating to the provision of system-wide coordinated control voltage regulation support in power transmission and distribution networks using multiple inverter based power generation facilities, which are coupled to the power transmission and distribution networks for minimizing transmission and distribution line losses. The invention uses a novel control method of inverter based Distributed Generators as Static Synchronous Compensator (STATCOM) in a way that provides a dynamic voltage regulation/control with the inverter capacity remaining after real power generation, thereby decreasing system line losses.

    摘要: Disclosed is a servo motor with a built-in drive circuit according to the present invention in which, when power is off, positional data including multiple-rotation counting values is stored in a nonvolatile memory to thereby eliminate battery back-up, and in which the CPU of a drive control circuit portion is in charge of the multiple-rotation counting itself to thereby eliminate the circuit for multiple-rotation counting. Due to a reduction in the number of lines involved and an elimination of battery back-up, a reduction in size is achieved. A servo motor with a built-in drive circuit according to the present invention includes an absolute encoder (30) for detecting rotation of a servo motor portion (100) and an electromagnetic mechanical brake (20), in which, when the power is off, the positional data (30A) at that time is stored in a nonvolatile memory.
