Abstract

The embodiment of the invention, which relates to the field of motor control, discloses an operation control method and device of a motor and a motor driver. The operation control method applied to amotor comprises: obtaining given angular position information; converting the given angular position information into an angle pulse number; according to a cycle interruption time of a timer, acquiring a counting pulse number; comparing the counting pulse number with the angle pulse number and outputting a position command based on a comparison result; and driving the motor to work to a given angular position based on the position command. According to the invention, a simple and reliable position control mode is provided to prevent instability of the instruction pulse and thus the motor performs the control instruction accurately during the operation process and works to the given angle.

Description

technical field [0001] Embodiments of the present invention relate to the field of motor control, and in particular to a motor operation control method, device and motor driver. Background technique [0002] The servo driver is a controller used to control the servo motor. With the development of computer technology and semiconductor technology, the control of the all-digital servo system is becoming more and more flexible. Existing servo drives generally control the servo motor through three closed-loop control algorithms of position, speed and current to achieve high-precision positioning of the transmission system. [0003] The inventors have found at least the following problems in the prior art: current, speed and position three closed-loop control algorithms based on vector control are generally used in the design of current AC servo drives. The commonly used position control setting usually adopts the command pulse mode. The host computer (PLC) sends a pulse train to...
