Manufacturing development makes a lot of original mechanical equipment are in produce and the requirement with efficient to high accuracy people cannot be satisfied more and more in treatment process, promoted technology of numerical control system to be used in the large area of machining industry again conversely, make numerical control technology makes a trade in machinery in suffer numerous rate to rise greatly. The application that article union is based on a system of H4-M numerical control that amounts to servo DELTA-ASDA to go up in machine of steel roller engraved designs, to machining control relevant technology craft and technical key are nodded.

Well-known, machine of steel roller engraved designs is one of auxiliary treatment facilities with the mainest rolling mill, with what control program form a complete set discusses in article it is machine of engraved designs of roller of steel of flying knife type (knife of the carve characters on a seal that place a head is contained on rigid structure) , machine of this kind of engraved designs has been in a steel, bao Gang and connect steel to wait large and medium-sized use in steelworks, it relatively before the machine of steel roller engraved designs of type of single pendulum head, treatment efficiency and treatment precision have substantially rise, the treatment that the formula that place a head uses previously chamfer of a roller needs 30min, and the mere need 20min that uses flying knife formula, make machined efficiency to rise thereby 1/3.

Base the advantage with above, regular on engraving tool of steel rolling roller meeting has the control program of the H4-M system that is based on DELTA-ASDA stage to amount to servo apparently to use a space capaciously. If the graph is shown 1 times,machine of engraved designs of roller of steel rolling of 2 control construction of system controls construction of system, does it comprise: by the following part? ELTA-ASDA of 﨑 of ù Sou Europe, PUTNC-H4-M of system of intent numerical control, the stage amounts to M TAPE transducer and intent hand to shake the composition such as round of PUMPG-BA4SI. Graph if requirement of technology of Nextpage3 of block diagram of 1 control construction of system and engraving tool of roller of craft specification steel rolling pursue show 2 times. The client is actual it is to use 5 axle control to machine flying knife, quarter child place head and workpiece collet to have engraved designs carve characters on a seal to roller of whorl steel steel rolling, among them of each axis name and function: X axis, the axis of; Y of transverse feed axis that controls deepness of flying knife engraved designs, control workpiece collet undertakes axis of gyral; Z of runner shaft coming back by the instruction, control carve characters on a seal places the axis of; A of runner shaft coming back of the head, the axis of; B of runner shaft coming back that controls the engraved designs that flying knife rotates by the instruction, control flying knife is fore-and-aft and mobile the feed axis that find new job. The particular mechanical movement of each axis and servo power: Axis of X, B is sharp movement rod, the ball silk lever that use pitch is 6mm and the join of servo electric machinery is connect means continuously, x axis is by the system pilot can move according to the instruction and, electric machinery power is 1.

5kW.

B axis is shake by a hand pilot, what servo uses is the position controls mode to use many gear than undertaking speed switch, can saying is one breaks away from the alone axis beyond the system; The score of subtrahend of runner shaft coming back of axis of Y, A, Z is not 72:1, 2:1, 1:1, make automatically control and shaking with the hand have nothing to do by the system, power of its electric machinery is 3kW respectively, 2kW, 1.

5kW, coder pulse fold is set for 2 times, is not normally 4 times. Graph the working principle that parameter reachs servo about numerical control related 4 numerical control and servo compares engraving tool of roller of 2 steel rolling simple, need not narrate more, the relevant parameter when numerical control and servo operation move gives out only here, the similar interface that systematic parameter installs is shown 3 times like the graph. Graph 3 systems parameter installs interfacial Nextpage (1) parameter of numerical control system 1) the fundamental parameter about each axis 0118: Mother of score of gear of electron of 00000005 X axis (compare set according to mechanical subtrahend) 0119: Gear of electron of 00000003 X axis compares an element 0120: Mother of score of gear of electron of 00000375 Y axis 0121: Gear of electron of 00000360 Y axis compares an element 0122: Mother of score of gear of electron of 00002500 Z axis 0123: Gear of electron of 00006000 Z axis compares an element 0124: Mother of score of gear of electron of 00000001 A axis 0125: Gear of electron of 00000036 A axis compares an element 0160: Fold of pulse of coder of feedback of 00000004 X motor is worth 0161: Fold of pulse of coder of feedback of 00000002 Y motor is worth 0162: Fold of pulse of coder of feedback of 00000002 Z motor is worth 0163: Fold of pulse of coder of feedback of 00000002 A motor is worth 0253: 00000000 X is 0 it is linear axis, for 1 it is runner shaft coming back 0254: 00000001 Y is 0 it is linear axis, for 1 it is runner shaft coming back 0255: 00000001 Z is 0 it is linear axis, for 1 it is runner shaft coming back 0256: 00000001 A is 0 it is linear axis, for 1 it is runner shaft coming back 2) the parameter that returns origin rate about axis of Y, A 0136: The first paragraph of rate that 00002000 X returns mechanical origin (Mm/min) 0139: The first paragraph of rate that 00001500 A returns mechanical origin (Mm/min) 0142: When 00000040 X answers mechanical origin, coder seeks GRID signal rate (Mm/min) 0145: When 00000150 A answers mechanical origin, coder seeks GRID signal rate (Mm/min) the parameter that answers origin speed to concern makes clear, axis of Y, A returns origin rate lower because the mechanical subtrahend of axis of Y, A is compared,be bigger, reduce an origin speed to be able to assure to answer 0 precision. (2) P1-01=2 of axis of servo parameter A, set servo controls mode to be speed mode P2-04=1758, speed controls gain P2-06=35, speed integral compensates P2-25=8, resonance restrains P2-26=257 of the low wave that connect filter, p2-10=101 of gain of exterior interference resistance, servo ON signal constant P1-00=0 of OFF B axis, set servo accepts P1-01=0 of pulse jussive type, set servo controls mode to be positional mode P1-44=5, electronic gear compares molecular P1-45=3, electronic gear compares denominator P2-12=143, switch electron gear is compared, × 10 P2-12=144, switch electron gear is compared, × 100 P2-60=50, gear of the 2nd electron compares molecular P2-61=500, gear of the 3rd electron compares P1-01=2 of molecular X axis, set servo controls mode to be speed mode P2-04=1318, speed controls gain P2-06=28, speed integral compensates P2-25=8, resonance restrains P2-26=301 of the low wave that connect filter, p2-10=101 of gain of exterior interference resistance, servo ON signal constant P1-01=2 of OFF Y axis, set servo controls mode to be speed mode P2-04=989, speed controls gain P2-06=35, speed integral compensates P2-25=7, resonance restrains P2-26=237 of the low wave that connect filter, p2-10=101 of gain of exterior interference resistance, servo ON signal constant P1-01=2 of OFF Z axis, set servo controls mode to be speed mode P2-04=1570, speed controls gain P2-06=50, speed integral compensates P2-25=5, resonance restrains P2-26=201 of the low wave that connect filter, p2-10=101 of gain of exterior interference resistance, servo ON signal often opens the gain parameter of servo of OFF 　 above, it is to pass use stage to amount to servo to debug software GAIN.

The response that EXE is compared according to different JL/JM laden inertia and differs computation of frequency wide BW comes out. Because the power of electric machinery is very great, very tall to the steel sex requirement of electric machinery, what so gain had better adjust as far as possible is a few taller, in order to satisfy the real requirement of treatment.
