A stepper motor control system for rotating a stepper motor by a desired amount of movement, including a first ROM (ROM3) for storing acceleration control data, a second ROM (ROM4) for storing deceleration control data and a change point control circuit for controlling a change point period between acceleration and deceleration. The change point control circuit assures that the acceleration is smoothly joined to the deceleration through the change point period so that the rotor of the stepper motor stops instantly and accurately at the target position. |
