摘要： A motor operation controller, which can accommodate different power supply voltages by changing a minimum circuit configuration using common motors, wiring, etc., has an insulation structure between input power supply and the motors for providing the capability of bidirectional operation in a power mode and a regeneration mode. The motor operation controller comprises a converter section and an inverter section for supplying power to a motor. In the converter section, there is an insulation type bidirectional DC voltage conversion function provided by an insulation type bidirectional DC voltage conversion section 32 having an insulation type bidirectional DC voltage converter 33, a controller 35, and a smoothing circuit 34.

摘要： A spindle drive system of a machine tool, wherein a control mode changeover section of a control unit selects one of both a speed control mode for controlling a rotational speed of a spindle through negative feedback of the rotational speed of the spindle and a position control mode for controlling a rotational position of the spindle through negative feedback of the rotational position of the spindle, and a gain changeover section changes speed loop and position loop gains to a greater value during cutting operation than during non-cutting rapid feed operation when the position control mode has been selected.

摘要： A gateway as one example of a mutual connecting appraratus between networks virtually provides an address of a mini manufacturing automation protocol (miniMAP) device to a mechatronics network (ME-NET) device in plural devices forming a network so that the miniMAP device uniquely identifies the ME-NET device. These plural devices connected to respective networks can mutually transmit and receive data in a network environment in which the ME-NET device is connected to the miniMAP device or another ME-NET device. Conversely, an address of the ME-NET device may be virtually provided to the miniMAP device so that the ME-NET device uniquely identifies the miniMAP device. Further, for example, the plural devices may be constructed by ME-NET devices. In this case, one ME-NET device uniquely identifies another ME-NET device in the plural ME-NET devices by virtually providing a station address unused in this one ME-NET device to this another ME-NET device.

摘要翻译： 作为网络之间的相互连接设备的一个示例的网关实际上将微型制造自动化协议（miniMAP）设备的地址提供给形成网络的多个设备中的机电一体化网络（ME-NET）设备，使得miniMAP设备唯一地识别 ME-NET设备。 连接到各个网络的这些多个设备可以在ME-NET设备连接到miniMAP设备或另一个ME-NET设备的网络环境中相互发送和接收数据。 相反，ME-NET设备的地址可以虚拟地提供给miniMAP设备，使得ME-NET设备唯一地识别miniMAP设备。 此外，例如，多个装置可以由ME-NET装置构成。 在这种情况下，一个ME-NET设备通过在该一个ME-NET设备中虚拟地提供未使用的站地址来唯一地识别多个ME-NET设备中的另一ME-NET设备。
