PROBLEM TO BE SOLVED: To simply enable automatically adjusting gain, integration time, etc., without assembling a speed adjuster in a machine in a site. SOLUTION: This automatic adjusting equipment is provided with a torque means value operating means 54 for operating te mean value of torque generated at the time of adjustable-speed operation, a torque limit value operating means 55 for operating a torque limit value smaller than the mean value when the mean value is smaller than a torque limit set value, a torque limiting means 51 for limiting a torque command value according to the torque limit value and performing torque limit acceleration and deceleration, a load inertia estimating means 52 for estimating load inertia from the torque limit value and the rate of change of speed, a gain operating means 53 for operating the gain of a speed adjuster 20 on the basis of the estimated value of load inertia and an equivalent time constant of a torque control system 30, and an integration time operating means for operating the integration time of the speed adjuster 20 from a gain operation value and the estimated value of load inertia. |
