Stepping motor control method, device and system

The invention relates to the field of stepping motor control, in particular to a stepping motor control method, device and system, the method is applied to a subdivision controller corresponding to a stepping motor, and the subdivision controller is connected with a main control circuit; the subdivision controller is connected with the stepping motor, the subdivision controller comprises a first register, and the subdivision controller controls the carrier frequency output to the stepping motor according to the current value of the first register so as to control the current operation state of the stepping motor. The carrier frequency corresponding to the value of the first register is provided by calculating and modifying the value of the first register, the carrier frequency is output to the stepping motor to achieve a target subdivision mode, automatic calculation and adjustment are achieved, errors caused by manual calculation and adjustment are reduced, and the control precision is improved. 本发明涉及步进电机控制领
