摘要: A stepping motor driving system and process according to the present invention controls a switching element in such a manner that motor supply current is passed through a motor coil until a coil current detection value reaches an upper limit set point, motor reflux current is passed through the motor coil until predetermined time elapses since the motor supply current begins to flow after the coil current detection value reached the upper limit set point, motor regeneration current is passed through the motor coil until the coil current detection value reaches a lower limit set point when predetermined time has passed, and motor reflux current is passed through the motor coil until predetermined time elapse since the motor regeneration current begins to flow after the coil current detection value reached the lower limit set point.
