Make simple introduction to electronic cam function below: 3.

1 what is electronic cam refers to a graph 5, cam is to be used at achieving concern of transmission of linkage of mechanical three dimensional space and pilot machinery structure. System of automation sport control uses concern of transmission of linkage of software program and three dimensional space of implementation of servo electric machinery and pilot software system is electronic cam function. From the graph 5 can see, left is our familiar mechanical cam pattern, and right is electronic cam means. The means that uses a program that is to say (cooperate servo unit) the orbit that achieves mechanical cam to control a need, achieve main shaft and the exercise of clench the teeth from the axis. Graph function of 5 electrons cam 3.

The implementation of 2 electrons cam (1) get main shaft seat. Get main shaft position to have a variety of methods: It is to use fictitious rod, computation is simple and accurate; 2 it is from main shaft coder or servo pulse are gotten, undertake signal of main shaft coder handling; 3 be from measure coder to get. After obtaining coder signal, its conversion becomes main shaft position. (2) the clench the teeth that realizes axis of principal and subordinate. It is the relation between axis of definition principal and subordinate actually (those who say for Cam Table) . Cam Table has two kinds of methods to state: It is to use the dot of X, Y to concern to the dot; 2 it is to use both function relationship. Of Cam Table get also have a variety of ways: The correspondence between the place that the basis measures in real work and dot concerns, concern according to the standard function of axis of principal and subordinate. Cam Table can define many Cam curve. After the relation decides and coming true, according to the position of main shaft, can get the seat from the axis. 3.

3 electronic cam stages that amount to athletic control PLC amount to 20PM motion controller besides implementation linear / besides circular arc interpolation and fixed position function, electronic cam function was embedded inside, make its can apply in a variety of motion to control a circumstance. 20PM is controller of 2 axes motion, have the input of 2 500KHz and output, in electronic cam function definition X axis is from the axis, y axis gives priority to an axis, after defining good Cam Table, the curve that defines from axial basis follows main shaft moves. Graph 6 it is electronic cam graph converts definition software advocate interface. The graph amounts to graph of electronic cam software 6 times to change a definition advocate the interface is in software we can use curve of cam of graphical means set, modification electron clearly. Click the meeting when entering a data to express single set pushbutton to play a section below to set a table when us. The person that use needs first set Start Ang, end Ang, stroke and choose sheet to choose CAM Curve through pull-down (have successive, sine, divide evenly to wait for 6 kinds of curves quickly, can join standard curve mixes other to define a curve oneself) , press after set is finished Setting Completed pushbutton, can be in advocate picture scale displacement, speed, acceleration coordinate graph is shown 7 times. The graph amounts to graph of electronic cam software 7 times to change definition interface to pursue 8 it is with high speed coil winding machine is the electronic cam graph of the exemple, use CYCLIC mode to discharge a line to circle line main shaft from axial basis successive positive and negative discharges a line. It is relation of axis of computational principal and subordinate calculates type below: Main shaft turns the space that circuit place gives a clue (round circumference) the gives a clue space that = π *D (mm) Or circles line mould circuit (round circumference) = π *D (mm) ; Platoon line turns from the axis circuit place needs pulse to count =10000P/R=> to should turn relatively the distance =10mm with circuit ball mobile screw; Main shaft rotates circuit place needs pulse =3600P/R => to rotate from main shaft of axial photograph correspondence what the pen number with circuit rotational place needs pulse = 100P/R => to answer relatively the distance =0 with ball mobile screw.

1mmMain shaft of Master/Slave relation =(rotates circuit place needs pulse * cam the v/LIT all over the ground number of one cycle) / (answer relatively from the axis main shaft rotates the v/LIT all over the ground number that the pen number with circuit rotational place wants * of means of pulse * line to discharge line width) pursue 8 high speed.

The key of programming is in 1 programming to reach a solution at the control difficulty analysis of high speed coil winding machine. (1) systematic difficulty. Coil winding machine appears in inverting place wind a string inhomogenous, accumulation; Occurrence spiral lamination of place of inverting of coil winding machine, rough whole; Cannot undertake inclined platoon winds a string, strange even number winds a string. (2) difficulty analysis. Inverting place winds a string because the speed of common PLC dictates processing time is long,case of inhomogenous, accumulation appears basically is, inverting suffers program scanning cycle to affect, dictate without synchronism and cannot real time refresh, servo is rigid at the same time parameter, trends answers speed also is one of reasons. Because helix circles line means to cause,inverting is in occurrence whorl basically is, can use half fixed position circles a line to solve finally. Inclined platoon circles every need when the line is climbing slope to add a line wide with the line thick, strange even number winds a string is a commutation is circled to circle turn to count odd even sex in every, after need winds a string every time, two kinds of means that wind a string have consideration, because time of operation of common and small-sized PLC is long, bring about cannot undertake high speed inclined platoon and strange even number wind a string. 4.

2 amount to a solution to be able to be seen by above analysis, the bottleneck of high speed coil winding machine depends on high speed operation reaching answer, and the stage amounts to 20PM motion controller to control the CPU of high speed operation that independence has outside CPU except logic, by hardware operation of the direct high speed that finish is answered, synchro control time is less than 2 axes 0.

5ms, achieve high speed to circle line demand. Amount to 20PM about the stage function of cam of athletic controller electron and application are above paragraphic already had a description. In addition, write to the program go to the lavatory very simply also, after using software of PMSoft process designing to install good Cam Table, the in-house register that controls correspondence directly can finish electronic cam to move. Watch 2 for bobbin of X axis platoon in-house register is expressed, different numerical value conveys to be able to come true in the D1511 in correspondence for example 0 (stop) , 1 (moving to the dot) , 2 (retrorse dot is moved) , 3 (odd paragraph of fast motion) , 4 (electronic cam moves) , other register has respective function likewise.
