Abstract
A load is driven by a statically controlled motor drive so as to follow a linear ramp characteristic recurrently, and a jump is caused to occur after each peak of the controlling ramp signal in order to compensate for inertia in the driven load. The inertia compensating jump is adjustable independently from the ramp parameters, and each ramp parameter is adjustable independently from the others as well as from the adjustment of the jump.
