Abstract
The determination of a slip constant is simplified upon driving a motor for which the slip constant is unknown, based on the acceleration time when accelerating an induction motor from start up to a predetermined rotation speed. A parameter determination support device for motor driving includes: an automatic measurement part which automatically measures characteristic information including the acceleration time upon driving an induction motor to accelerate from start up to a predetermined rotation speed set in advance, relative to each slip constant, based on a plurality of slip constants set in advance; and an estimation part which estimates, as the slip constant of the induction motor, a slip constant at which the acceleration time up to a predetermined rotation speed becomes the shortest, among a plurality of slip constants, based on the characteristic information.
