Parameter determination support device, parameter determination supporting method, and program

摘要

The determination of a slip constant is simplified upon driving a motor for which the slip constant is unknown, based on variation of acceleration when accelerating an induction motor from start up to a predetermined speed. A parameter determination support device for motor driving includes: an automatic measurement part which automatically measures characteristic information including a speed during acceleration and acceleration upon driving an induction motor to accelerate from start up to a predetermined speed set in advance which is no more than a base speed of the induction motor, relative to each slip constant, based on a plurality of slip constants set in advance; and an estimation part which estimates, as a slip constant of the induction motor, a slip constant having the smallest variation in acceleration, among a plurality of slip constants, based on the characteristic information.
