摘要： This invention relates to methods and devices for motor speed control. The invention has particular application in the control of motors over packet networks. In embodiments of the invention, phase-locked loop principles are used to remotely control the speed of an electric motor over a packet network. The setpoint for the motor is supplied by arriving timestamps from a speed-mapped variable frequency source. The shaft speed of the motor is measured with a tachometer with its output proportional to the motor speed. Any deviation of the actual speed from the setpoint is amplified by the power amplifier whose output drives the motor. Speed control over packet networks allow smoother operation of a process, acceleration control, different operating speeds for each process recipe, compensation for changing process variables, slow operation for setup purposes, adjustments to the rate of production, accurate positioning, and control torque or tension of a system.

摘要： A motor control device includes a measuring unit configured to output a measurement value corresponding to a rotation speed of a motor; and a control unit configured to control driving of the motor such that the measurement value makes closer to a target value. When the measurement value does not exceed a predetermined abnormality determination threshold, the control unit controls the driving of the motor based on a difference between the measurement value and the target value. The abnormality determination threshold is set in a positive direction or in a negative direction with reference to the target value. When the measurement value exceeds the abnormality determination threshold, the control unit controls the driving of the motor based on a difference between a corrected measurement value and the target value. The corrected measurement value is set in the same direction as the direction in which the abnormality determination threshold is set.

摘要： A motor drive device includes a drive controller for generating drive signal “trq”, a limiter for limiting a value of drive signal “trq” within a range, a limit value generator for generating limit value “lmt”, and a drive output section for generating an energizing signal in response to an output signal from the limiter. The limit value generator generates a comparison signal by adding offset value “ofs” to drive signal “trq” and updates limit value “lmt” based on a size relation between a value (trq+ofs) of the comparison signal and limit value “lmt”.
