Abstract
The present invention provides a method and apparatus, including a processor and software incorporating a table that contains sets of pre-determined correction values that are used to supply different amounts of power to an electric stepper motor when the motor is operating at different speeds. Use of the correction values in the table allows power to be supplied to the motor in differing amounts that are approximately the same as the power actually required by the motor at different motor speeds or ranges of speeds.
