Problems solved by technology

[0002] In the mechanical equipment for cutting sponge, it is necessary to drive two servo motors at the same time to pull a saw blade and cut the sponge like a saw. Obviously, this needs to control the synchronous rotation of the servo motors, otherwise the knife will be easily broken. At the same time, the mechanical part of the equipment will be greatly damaged, seriously affecting the stability and service life of the electromechanical equipment, so the synchronous control of the servo motor is the key
[0003] At present, there are materials that disclose a synchronous operation control system, which uses an encoder to det

Example Embodiment

[0017] Such as figure 1 As shown, input 1 of the servo motor synchronization control card is the load input of servo motor A, input 2 is the load input of servo motor B, input 3 is the speed input of servo motor, and input 4 is the input port of servo motor speed command. , The output terminal 5 is the drive output of servo motor A, the output terminal 6 is the drive output of servo motor B, and the output terminal 7 is the computer interface.

[0018] figure 2 Shown is the program block diagram of the servo motor synchronous control system. Step 101: Initialize first, and assign appropriate initial values ​​to the relevant storage units. Step 102: Detect the motor speed command, if the motor speed is detected, go to step 201, if the motor speed is not detected, go to step 401.

[0019] Step 201: Analyze the motor speed command. If it is analyzed that it is a stop command, control the motor to stop. Step 301 returns to step 102. If it is analyzed that it is a low-speed, medium-s...

Abstract

The invention relates to a motor synchronous control system of a sponge cutting machine, which comprises two servo motors and a servo motor synchronous control card with a program chip, outputs of the servo motor synchronous control card are drive outputs of the two servo motors and a computer interface, and inputs thereof are loading inputs of the two servo motors, a motor rotating speed input and a motor rotating speed instruction input. The servo motor synchronous control card comprises the steps for controlling the motor synchronization: a. detecting and analyzing the rotating speed of the servo motors; b. detecting the load data of the two servo motors; c. analyzing load data errors of the two servo motors; d. adjusting phases of the two servo motors; and e. adjusting phases of the two servo motors according to the load data errors obtained in the step d, so as to keep the load data errors of the servo motors in the normal range. The motor synchronous control system of the sponge cutting machine has advantages of stable and reliable running, high degree of integration, low price, and being favorable for further improving the motor synchronous operation performance of the sponge cutting machine.

Description

technical field [0001] The invention relates to a synchronous control system of a motor, in particular to a synchronous control system of a servo motor of a sponge cutting machine. Background technique [0002] In the mechanical equipment for cutting sponge, it is necessary to drive two servo motors at the same time to pull a saw blade and cut the sponge like a saw. Obviously, this needs to control the synchronous rotation of the servo motors, otherwise the knife will be easily broken. At the same time, the mechanical part of the equipment will be greatly damaged, seriously affecting the stability and service life of the electromechanical equipment, so the synchronous control of the servo motor is the key. [0003] At present, there are materials that disclose a synchronous operation control system, which uses an encoder to detect the motor speed in real time, and calculates the rated speed of the main motor and the rated response speed of each slave motor through a programm...
