摘要： In controlling, with recognition of their installation positions, the opening/closing driving of plural doors that are driven by respective linear motors, each door is driven closed by switching the door opening/closing drive torque to high torque if the drive speed of the door has become less than or equal to a prescribed speed. In doing so, operation instruction computing sections set high torque application periods for respective doors so that the periods of high-torque closure driving of respective doors or predetermined door groups do not overlap with each other, and issue instructions to drive the doors closed with high torque only during the high torque application periods.

摘要： A method and system for controlling motor torque provides improved responsiveness and reliability in motor control applications. The motor control system includes a power converter, a voltage detector for detecting the converter input voltage and a control circuit for controlling the converter. The control circuit includes a torque command limit value generator and a torque command limiter for limiting a torque command value. The system may also include a torque command coefficient generator for generating a coefficient corresponding to an input current of the power converter, and a multiplier for calculating a final torque command value for the motor by multiplying together the torque command value and the torque command coefficient. The torque command limit and coefficient values may be determined from the converter input voltage, calculated or detected converter input current and calculated input impedance between a power supply and the converter.

摘要： A door drive control apparatus capable of an accurate detection, without misidentifying an inverse overrun condition, and a door drive control method that improves safety. The door drive control apparatus includes a power converter that supplies power to a door drive linear motor, and operates the power converter by feedback control using a speed detection value and a speed command value of the door, and controls a speed of the door. The door drive control apparatus includes a speed trouble determiner, which outputs a door inverse direction speed trouble signal in the event that the speed command value of the door exceeds either a positive or negative first setting speed, and the speed detection value exceeds a second setting speed of a polarity opposite to that of the speed command value.
