Abstract
In one embodiment, the invention involves a method for controlling a stepper motor. The method includes creating an information set that defines a first acceleration profile of a stepper motor and a first deceleration profile of the stepper motor; and directing the stepper motor to follow either a second acceleration profile or a second deceleration profile after the stepper motor begins to follow either the first acceleration profile or the first deceleration profile. In another embodiment, the invention is a stepper motor controller that includes a circuit configured to store an information set that defines a first acceleration profile of a stepper motor and a first deceleration profile of the stepper motor; and direct the stepper motor to follow either a second acceleration profile or a second deceleration profile after the stepper motor begins to follow either the first acceleration profile or the first deceleration profile.
