Abstract
PURPOSE:To permit full utilization of adjustable speed torque by a simple circuit, by a method wherein the amount relating to adjustable speed torque is obtained from the overload characteristic curve at the time of acceleration of a power converter and the characteristic curve of a load device and the adjustable speed rate is adjusted in accordance with the amount. CONSTITUTION:A signal l3 closely resembling the load torque with square-law characteristics is generated from a function generator 36 by using frequency reference f as input and the signal l4 of load amount Tc at adjustable speed decided by a power converter is set by a setting unit 37. The signal l5 of accelerating torque amount at the time of acceleration is generated by a subtracter 38 by using the signals l3, l4 as input and the signal l5 is added by an adder 39 by using the signal l3, l4 as input. The signal l5 is inverted to generate 40 the signal l6 of decelerating torque amount at the time of speed reduction.
