Description
Technical field
The present invention relates to the synchronous control system of motor, especially a kind of synchronous control system of servomotor of sponge cutting machine.
Background technology
In the plant equipment of cutting sponge, to drive two servomotors simultaneously, spur a saw cutter, as the saw cutting sponge, obviously this just needs the control servomotor to rotate synchronously, otherwise this cutter is easy to be broken, when breaking, the Machinery Ministry branch of equipment is subjected to very big damage, has a strong impact on the stability and the useful life of electromechanical equipment, and the synchronous control of servomotor is a key thus.
There is data to disclose a synchronous operation control system at present, it adopts encoder to detect motor speed in real time, calculate the normal speed of main motor and respectively from the specified response speed of motor by Programmable Logic Controller, main encoder is with umber of pulse that current main motor produced, output in real time on each frequency converter Synchronization Control card, control motor real-time response, relative conventional method, the parts degree of integration increases, can realize instruction chemical control system, connection line is also relatively simplified, but adopts this method cost very high, the integrated degree of parts is high not enough, and failure rate is many.
Summary of the invention
Task of the present invention provides a kind of motor synchronous control system of sponge cutting machine, its stable and reliable operation, and integrated degree height, cheap, help further improving the servomotor synchronous operation performance of sponge cutting machine.
The motor synchronous control system of the sponge cutting machine among the present invention, it comprises two servomotors and a servomotor Synchronization Control card that has program chip, described servomotor Synchronization Control card is output as the driving output and the computer interface of two-way servomotor, is input as load input, motor speed input and the motor speed instruction input of two-way servomotor.
The step of described servomotor Synchronization Control card control motor synchronous is:
A. detect and analyze the servomotor rotating speed;
B. detect the load data of two-way servomotor;
C. analyze the load data error of two-way servomotor;
D. adjust the phase place of two-way servomotor;
E. according to the load data error of steps d generation, adjust the phase place of two-way servomotor, make and wait for an opportunity to obey the load data error of motor in normal range (NR).
The method that described step a detected and analyzed motor speed is the pulse signal according to the input of the motor speed input on servo Synchronization Control card motor speed, and two trailing edges by calculating this pulse signal or two rising edges are measured the current rotating speed of motor.
Described step b detects the load data of two-way servomotor, and these data have data school searching symbol and field.
Adopt to analyze the method for load data error, control two servomotors, guaranteed two servomotors synchronously, take place asynchronously to cause that to break the probability of sawing cutter minimum, prolonged the stability and the useful life of electromechanical equipment.
Description of drawings
Fig. 1 is the block diagram of servomotor Synchronization Control card;
Fig. 2 is the flow chart of servomotor synchronous control system.
Embodiment
As shown in Figure 1, the input 1 of servomotor Synchronization Control card is servomotor A load input, input 2 is the servo motor B load input terminal, output is gone into end 3 and is the input of servomotor rotating speed, input 4 is servomotor rotary speed instruction input port, output 5 drives output for servomotor A, and output 6 drives output for servo motor B, and output 7 is a computer interface.
Figure 2 shows that servomotor synchronous control system flow chart, step 101: at first initialization, give suitable initial value to relevant memory cell.Step 102: detect the motor speed instruction,,, then enter into step 401 if do not detect motor speed if detect motor speed then enter into step 201.
Step 201; instruction is analyzed to motor speed; if analyzing is halt instruction; stop by the control motor; step 301 turns back to step 102, is low speed, middling speed or instruction at a high speed if analyze, or the words of a certain command speed instruction; then control motor to corresponding low speed, middling speed or high speed, or the operation of a certain command speed.
After the motor operation, enter into step 302, it is the current rotating speed of testing of electric motors, the current rotating speed of motor is to measure like this, with there being a motor speed pulse signal input terminal to receive the pulse signal of relevant motor speed in the control fabrication, calculate two trailing edges or two rising edges of this pulse, can measure the current rotating speed of motor, and judge whether it is the rotating speed of setting, as pulse-free signal, the expression motor is in halted state, and program turns back to step 102, if pulse is arranged, no matter motor is in low speed, middling speed or high speed, no matter whether be in the speed of setting, all will carry out load detecting, i.e. step 501.
With 2 servomotor load input terminals are arranged in the control fabrication, input 1 and 2, instruct according to the data read that servomotor manufacturer provides, can read the present load data of servomotor A and B, these data have data check character and field, can know whether data make mistakes, if data are made mistakes, then turn back to program 102,, then carry out A and the analysis of B motor load data difference if sense data is correct.
If the load data difference of A and B motor is in normal range (NR), normal range (NR) generally is that 5 programs turn back to step 102, if error range greater than 8, is then adjusted the rotatable phase of two-way motor.
Just arrived step 701, adjusted the rotatable phase of two-way motor, the method for phase adjustment of two-way motor is to adjust by the result who adjusts again.If the result that adjusted last time dwindles the load data difference of two-way motor, then continue to adjust.If the result who adjusted last time amplifies the load data difference of two-way motor, then oppositely adjust.The load data difference that makes the two-way motor up to the result who adjusts is in normal scope.
