ABSTRACT:
An acceleration shaping circuit for a stepper motor is described and includes two voltage storage devices. One is charged linearly and the other is charged exponentially. The output ramp voltage is an adjustable combination of the two stored voltages and is therefore variable between a linear ramp voltage and an exponential ramp voltage.
