[CN 201910811435.7] Automatic Compensation Method for Motor Command of Lower Dead Center Deviation of Servo Press
[CN 201910811435.7] A Servo Press Lower Dead Center Deviation Motor Command Automatic Compensation Method Title: A Servo Press Lower Dead Center Deviation Motor Command Automatic Compensation Method Application Number: CN 201910811435.7 Applicant: Shandong Academy of Sciences Laser Research Institute Application Date: 2019-8-29 Patent Type: Invention Application The present invention discloses a servo press lower dead center deviation motor command automatic compensation method, which uses a slider displacement sensor to detect the difference between the lower dead center actual value and the expected value, the general slider displacement sensor uses a grating ruler, and then the internal software of the controller adjusts the motor position control command curve, that is, the stamping curve, according to the size and direction of this deviation, so as to reduce the bottom dead center error in the next stamping process. As this compensation operation is repeated in each stamping cycle, the difference between the actual position of the slider and the expected value can be gradually eliminated after several stamping cycles, and finally the purpose of completely eliminating the error can be achieved. Because this compensation process is done automatically in the controller's internal software, it can be done quickly without the need for additional mechanical equipment. In addition, the adjustment range of the control command by the software can be very fine, so this method can make the bottom dead center deviation infinitely reduced, so that the accuracy of the bottom dead center can be greatly improved.
