Grind the application that accuses servo driver to go up in machine of numerical control bedspring

M, but need not choose rated torsion to be 21N.

The communication servo electric machinery of M enters electric machinery for ride instead of walk. The maintenance that the pace enters electric machinery torsion is electric machinery rotate speed is the 0 torsion when, it is the biggest torsion that the pace can achieve into electric machinery, as rotate speed elevatory, the torque that the pace outputs into electric machinery attenuation, if the graph is shown 2 times,the pace enters curve of frequency of electric machinery quadrature. And the character that communicates servo electric machinery is to be in 0 arrive between rated rotate speed, the torque of electric machinery is constant and changeless. The real load of equipment is less than 6N.

M. Nextpage pursues 2 　 next, type selecting speed. Equipment by share two axes -- cutting tool axis and send bobbin. Cutting tool axis drives cutting tool through cam, every turn a week, process a work, rotate speed of cutting tool axis sends bobbin every in; of 500r/min left and right sides transmit line length to be 144mm, want those who achieve 150m/min to send linear velocity, the requirement sends rotate speed of bobbin electric machinery to be 1042r/min. Additional, inertia type selecting. The ratio of laden inertia and electric machinery inertia calls inertia comparing. Of the size influence system that inertia compares case stop function. Facility work status stops to rise often, every machine a workpiece to one is started stop a process. When treatment speed reachs maximum, electric machinery is minutely case stop 500 times. Rise goodly to obtain stop function, inertia is a few smaller than should choosing, this second choice is in 3: 1 the left and right sides. According to above regulation, choose drive model YKPSDD_10A5D, if electric machinery parameter expresses 3 to show. Because manage servo electric machinery contains photoelectricity coder, so electric machinery length increases somewhat. Coder precision is 2500 lines, driver interior passes 4 times frequency, make the pulse equivalent of servo is 0.

036 ° , it is 50 times what the pace enters electric machinery. Watch 3 　 are pure tell from the angle of pitching moment, when former condition achieves 1200r/min into electric machinery rotate speed, torsion still is in 6N.

M left and right sides, satisfy the requirement of drive, but the acceleration that the pace enters electric machinery ability is no good. When treatment speed is 500 workpiece / when minute, time of the electric machinery inactive that start is very brief, quicken 1000r/min into electric machinery to the pace without enough time, the phenomenon of occurrence pace, and servo electric machinery can be finished successfully however quickly. 4, parameter adjustment presses a manual correct wiring. Whether to put even the line in breakdown for the test, enter test mode to move above all. Grind accuse servo to offer mode of two kinds of tests, can check the position to control mode and speed control mode respectively. The course checks, affirm mechanical join and electric join are normal. Get on join next an accident travel. Go up a machine the computation of the athletic status that achieves pair of two axes, transmit athletic condition servo driver with the form of pulse, carry out by electric machinery of servo of servo driver drive go up the operation result of a machine. The control system block diagram of bedspring machine shows 3 times like the graph: Graph 3 　 with 100 workpiece / minute rate moves, it is normal to move. Continue to raise treatment rate, when treatment speed obtains 370 work / when minute, appear the phenomenon of the line, namely rotor position exceeded quit the position, recede next time, because driver tigidity is insufficient,this is, need adjustment parameter, improve performance. A few bigger to systematic performance influence parameter are integral of positional scale gain, speed gain of gain of scale of time constant, position, the make a present of before the position. (1) [speed scale gain] (parameter PA-5) set value, below the condition that does not produce vibration, as far as possible set is gotten bigger. Set value is greater, tigidity is stronger, but set is too big, may produce vibration. Usually, laden inertia is bigger, [Speed scale gain] set value should be jumped over big. (2) [speed integral time is invariable] (parameter PA-6) set value, the basis is given condition, install more greatly as far as possible. [The constant between speed accumulating time-sharing] of set too big when, answer speed to will rise, but easy generation oscillation. Fall in the condition that does not produce vibration so, what install as far as possible is bigger. [The constant between speed accumulating time-sharing] of set too big when, when load is fluctuant, speed will be fluctuant bigger. Usually, laden inertia is bigger, [The constant between speed accumulating time-sharing] set value should be jumped over small. (3) [positional scale gain] (parameter PA-9) set value, inside stable range, install more greatly as far as possible. [Positional scale gain] when be being installed too greatly, the position dictates dog character is good, lag error is small, but when quiting fixed position, produce vibration easily. (4) if ask the position dogs when character is particularly tall, can increase [gain of the make a present of before the position] set value. But if too big, can cause exceed tone. According to above adjustment rule, speed scale gain from 52 increase 80, ask the problem is solved, arrive all the time 500 workpiece / minute treatment speed, did not appear the phenomenon of the line. 5, conclusion profit from grinds accuse to communicate servo driver to be aimed at different situation beforehand buy different parameter, the process that whole parameter debugs simplified a lot of. Of bedspring machine send bobbin job to be in open the position that park often, to communication servo, this is the working environment of a kind of Yan Ke. Grind the success application that accuses servo to go up in bedspring machine, proved adequately to grind the good quality that controls a product. CNC Milling CNC Machining
