Abstract
To provide a parameter determination support device and a program capable of simplifying determination of driving parameters upon driving a motor for which the slip constant is unknown. A parameter determination support device includes: an acquisition unit for acquiring specification information of a drive device of a motor and output specification information of an induction motor; an initial parameter determination unit for determining an initial parameter for test running, based on the specification information and the output specification information; a program creation unit for creating a test-run program to be used in test running for acquiring data that is required for adjustment of a parameter that determines output of the induction motor, based on the output specification information; an automatic measurement unit for automatically measuring a Q-phase voltage command of the induction motor according to the speed, as operating information upon driving by varying the speed of the induction motor according to the test-run program by applying the initial parameters; an estimation unit for estimating a slip constant of the induction motor, based on the operating information; and a calculation unit for performing calculation of an optimum parameter tailored to the output specification of the induction motor, based on the slip constant.
