Abstract

The invention provides a motor out-of-step compensation method and device, and the method comprises the steps: starting an optical coupling circuit in response to an inputted motor out-of-step recovery instruction so as to obtain the target output level of the optical coupling circuit; determining estimated coordinates of a corresponding motor physical position when the target output level jumps based on the relationship between the target output level and a preset optocoupler output level; and determining the target compensation value of the motor based on the estimated coordinates of the motor physical position so as to compensate the motion step number of the motor based on the target compensation value. The problems of lens out-of-focus and blurred image imaging caused by out-of-step of the motor are solved.

Description

technical field [0001] The invention relates to the field of motor drive, in particular to a motor out-of-step compensation method and device. Background technique [0002] The motor is an open-loop control motor that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulse signals, and are not affected by load changes. Influence, when the stepper driver receives a pulse signal, it will drive the motor to rotate a fixed angle in the set direction, called "step angle", its rotation is run step by step at a fixed angle, which can be passed Control the number of pulses to control the angular displacement, so as to achieve the purpose of accurate positioning; at the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.
