PURPOSE:To smoothly control the rotation of a stepping motor by accurately setting the driving pulse interval of a high speed rotating stepping motor. CONSTITUTION:Memory means 4 stores a driving pulse interval for accelerating a stepping motor 5 to or decelerating it from a contact speed. A controller 3 calculates a set value based on the interval in response to the state of the acceleration or deceleration of the motor 5, applies it to first counting means 1, and drives the motor 5 in response to the signal from the means 1. The interval of the driving pulses of the motor 5 becomes the sum of the counting time of the first means 1 and the counting means of second counting means 2 to become an accurate value. Thus, the motor 5 is smoothly accelerated, decelerated or operated at a constant speed without stepout. |
