Parameter determination support device, and non-transitory computer-readable medium encoded with program

A parameter determination support device for motor driving, comprising:

• an acquisition means for acquiring specification information of a motor drive device and output specification information of a synchronous motor;
• an initial parameter determination means for determining an initial parameter for test running, based on the specification information and the output specification information;
• a program creation means 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 synchronous motor, based on the output specification information;
• an automatic measurement means for automatically measuring a D-phase current, DC link voltage and Q-phase voltage command of the motor drive device, as operating information upon driving the synchronous motor at a substantially constant speed under each condition of a first condition based on a base speed, and a second condition in which the D-phase current of the motor drive device was changed from the first condition, according to the test-run program, by applying the initial parameter;
• an estimation means for estimating a short circuit current and a D-phase inductance, as circuit constants of the synchronous motor, based on the operating information;
• and
• a calculation means for performing calculation of an optimum parameter tailored to the output specification of the synchronous motor, based on the circuit constants.
