摘要： A system for controlling the driving of a stepper motor which is rotated by the driving pulses generated based on the two-phase excitation system for rotating a driven system is disclosed herein comprises when the frequency of said driving pulses is outside of the resonance ranges of said stepper motor and some predetermined component parts of said driven system, respectively, the driving pulses generated based on said two-phase excitation system are applied to said stepper motor to rotate the same, but when the frequency of said driving pulses is within said resonance ranges, a brake pulse and a power suppression portion are added to said driving pulses so that said stepper motor is caused to rotate without causing resonance and can be stopped at a predetermined position with a high degree of accuracy and furthermore noise can be suppressed to a minimum.
