PURPOSE:To provide a torque controller which can perform the high speed control with high precision by providing the speed limiter function. CONSTITUTION:A speed limit signal is outputted by detecting the variation of the speed over a previously set error from the control speed, and the torque instruction value is corrected according to the deviation value between the limit signal and the actual speed. In this case, a control amplifying function 6 for amplifying the deviation value between the limit signal and the actual speed and an adder 7 are installed, and the torque instruction value is corrected by the addition of the control amplifying function output signal and the torque instruction value. Further, the control amplifying function is provided with the integration function, and the integration function is desirably set when the actual speed and the limit signal value are set in a prescribed relation. |
