Ying Wei soars the application of function of servo DA200 complete closed circuit in grinder

2 craft brief introduction is ground normally rotate give priority to motion, working whirl and shift or grind provided shift to be feed motion. Grinder machines effect to lead limits of tall, application because of its wide, adaptability strong, use cost low, safety in operation goes to the lavatory to wait for a characteristic and look at in person by the user. Grinding is a kind of stretch grinding, it is one kind has grinding, abrade, polish the compound treatment craft of a variety of action. 2, the grinding machine of numerical control tool that brief introduction of grinder equipment market looks forehead divides domestic company to already can produce inferior end, grinding machine of tool of high-end numerical control still is given priority to with the entrance. As domestic company technology accumulate, had narrowed greatly the difference between as lead as international company, grinding machine of tool of homebred numerical control begins to show than the advantage that go up in sexual price, respect entrance needs to replace inside begin to quicken, scale of grinding machine of tool of export side numerical control is in step up, exit begins to carry fast. Numerical control grinder is being spent at industry boom rise period. The servo brand that course of study of one's own profession chooses at present has roughly: Series of J2S of 5 series of Ⅱ of Japanese An Chuan ∑ , ∑ , 3 water chestnut, J3, J4, stage amounts to A2 series to communicate servo, Ying Wei to vacate DA200 series to communicate servo. Numerical control grinder is very slashing to communicating the requirement of servo, 100 times successive treatment repeats ≤ of error of fixed position precision 2 μ M, the 1 μ of ≤ of on size error after grinding M, operating mode of domestic grinding treatment is more abominable, for example voltage flabby, high temperature is high wet, tall pollution. Because entrance product price is very high, after service satisfies the client's requirement very hard, to the client's production quality of credit of cost, machine tool, service increased a lot of troubles and burden. Because this client is searching a gender all the time valence comparing is taller, the homebred servo brand with more seasonable and considerate service. And Ying Wei vacates DA200 to depend on answer high accuracy, high, price of complete closed circuit, tall sex compares exceed strong performance to reach custom-built those who changed a service to win a client approbate. 3, applied plan introduces 3. Servo of 1 complete closed circuit and the distinction of half closed circuit servo half closed circuit is to show numerical control system issues a statement, servo accepts a statement, carry out next, in executive process, the coder of servo itself undertakes positional feedback gives servo, him servo undertakes deviation is amended, servo itself error can avoid, but mechanical error cannot avoid, because numerical control system does not know. Complete closed circuit is to show servo accepts a statement, carry out next, in executive process, there is the unit that the position feedbacks on machine, direct feedback gives numerical control the system, numerical control system is passed quite, judgement goes out with factual error, give servo the statement, undertake deviation is amended. 3. The important part of 2 complete closed circuit- - feet of grating feet grating, also call sensor of grating feet displacement (grating feet sensor) , be the optical principle job that uses grating survey feedback plant. Grating feet often applies in the closed circuit servo of numerical control machine tool, can use as linear displacement or of angular displacement detect. Its measure the pulse of word of signal amount to of output, have detect range is big, detect precision is tall, answer the characteristic with rapid rate. 3.

The lever of control program silk of grinder of 3 half closed circuit has lead space, machine the error that moving inaccuracy decides to be in all the time back and forth. Mechanical drive run time is longer, wear away fiercer, treatment does not decide the error also can be in increase. 3. 4 INVT grinder dominates program 3. 4. 1 system configures a graph 3. 4. Power of brand of name of configuration of 2 electric type selecting (KW) precision amount (stage) communication servo Ying Wei vacates Ying Wei of DA20011 servo electric machinery to rise 117 absolute value resolution of case of hair of 1 grating feet is 0.

On 001mm1 machine HUST13. 4. 3 plan advantage 3. 4. 3. 1.

The grating rule that laden end installs is received outside support, realize full closed-loop control, reduce mechanical drive to carry unoccupied place influence on the back, more ensure machine terminal locates precision. 3. 4. 3. 2 measure exterior and laden journey directly, overcame the worry that the transmission error that causes as a result of mechanical wear increases effectively. 4, servo is debugged reach parameter to install 4. 1 servo hookup 4. Module of control of wiring of signal of 2 control line is NPN model (in all cathode) if do not need directional signal, need to receive 38 feet OCP to receive 24V+ and 24 feet PULSE- to receive PLC pulse output only. 4. 3 servo parameter sets a table 4. The online oscillograph passageway that 4 USB corresponds is undee 4. 5 servo debug main measure: 4. 5. 1.

Beard of direction of feet of 62 settings grating and servo electric machinery are consistent, if different, need direction is taken instead, can fly otherwise car. In addition, still but P4.

Limits of pulse of 33 positions out of tolerance is set small to appropriate value, acquiescent value is 100000.

At the same time P4 of the biggest speed limit.

31 also can install be restricted to be worth suitably. Can handle caused flying car in order to prevent by accident so, made can be broken for instance, on still delivering pulse all the time, exceed P4.

33 servo called the police. Prevent to be added thereby make can be met the phenomenon of flying car. 5, plan summary: A) repeats fixed position precision to be 2um less than, achieved the client's requirement. B) and photograph of half closed-loop control are compared, machinery of new machine of half closed circuit is not had wear away, although can pass compensation to overcome clearance of filar lever lead, but time is long, wear intensity is not affirmatory, machining error is increased, and the settlement with very good system of complete closed circuit problem of this hard injury, create the greatest value for the client. Function of C) complete closed circuit makes DA200 in athletic precision, output flexible, speed and acceleration control a dominant position very apparent, with one action broke the firm ice of entrance servo, become industry celebrity.
