MOTOR DRIVE METHOD FOR AUTOMATICALLY CONTROLLING AMPLITUDE AND STOP OPERATION

摘要

PURPOSE: A motor drive method is provided to automatically control weaving motion of oscillator and stoppage of motor operation at a weaving end. CONSTITUTION: A motor drive method, comprises a first step of converting a low level into a high level when the number of pulses fed back from an encoder is matched to the number of pulses corresponding to a weaving width value set in a timer; a second step of changing motor direction by using an interrupt A(30), and preparing a mode B(40); a third step of determining timer operation starting time of the mode B by using the interrupt generated in a mode A(20); a fourth step of preparing the mode A by generating an interrupt B(50) at the point when the number of pulses preset in the timer of the mode B passes a stop time; and a fifth step of generating the interrupt A when a predetermined weaving time has lapsed after starting of the motor, and stopping the motor until the mode B is executed.
