High-response servo driver

Abstract

The invention provides a high-response servo driver which determines corresponding operation position offset and torque adjustment amount output by a servo motor by detecting and analyzing real-time operation position information of the servo motor. According to the torque adjustment amount, a corresponding rotating speed adjustment instruction is generated so as to adjust the rotating speed of the servo motor; detecting and analyzing the real-time operation position information of the servo motor again so as to determine the secondary operation position offset of the servo motor after the rotating speed is adjusted; and finally, switching and controlling a switch working state of the servo motor according to the secondary operation position offset, so that closed-loop control can be carried out on the servo motor at three levels of operation position, torque and rotating speed, the torque and the rotating speed of the servo motor are adjusted by taking the operation position of the servo motor as a reference, and the control precision of the servo motor is improved. And the servo motor is closed under the condition that the offset of the operation position of the servo motor is too large, so that the driving control response speed of the servo driver to the servo motor is improved, and stable and continuous operation is ensured.

Description

technical field [0001] The invention relates to the technical field of servo drives, in particular to high-response servo drives. Background technique [0002] A servo drive is a drive device used to drive a servo motor. In actual work, the servo driver usually controls the servo motor in three aspects: the operating position, output torque and operating angular velocity, so as to realize the stable and continuous operation of the servo motor. The control mode based on the operating position, output torque, and operating angular velocity of the prior art has a slow response speed, and cannot perform dynamic and timely drive adjustments according to the actual working state of the servo motor, thereby reducing the position control accuracy and speed of the servo motor. performance and cannot guarantee the stable operation of the servo motor.

[0003] Aiming at the defects existing in the prior art, the present invention provides a high-response servo drive, which determines the corresponding operating position offset and the output torque adjustment of the servo motor by detecting and analyzing the real-time operating position information of the servo motor; Torque adjustment amount, generate the corresponding speed adjustment command, so as to adjust the speed of the servo motor; then detect and analyze the real-time running position information of the servo motor again, so as to determine the secondary running position offset of the servo motor after the speed adjustment; Finally, switch and control the switch working state of the servo motor according to the offset of the secondary running position, so that the closed-loop control of the servo motor at three levels of running position, torque and speed can be performed, and the servo motor is controlled based on the running position of the servo motor. Adjust the torque and speed of the motor, and turn off the servo motor in time when the deviation of the servo motor's operating position is too large, so as to improve the response speed of the servo driver to the drive control of the servo motor and ensure the stable and continuous operation of the servo motor
