1. Molao-motheo oa ho sebetsa oa mokhanni oa servo:
Hona joale, bakhanni ba servo ba tloaelehileng kaofela ba sebelisa digital signal processor (DSP) e le setsi sa taolo, se ka khonang ho lemoha algorithm e rarahaneng ea ho laola, le ho hlokomela digitalization, marang-rang le bohlale.Lisebelisoa tsa motlakase ka kakaretso li sebelisa intelligent power module (IPM) e le moralo oa mantlha oa potoloho ea drive, IPM internal integrated drive circuit, 'me e na le overvoltage, overcurrent, overheating, undervoltage le potoloho e 'ngoe ea ts'ireletso ea phoso, potolohong e kholo e boetse e ekelitse potoloho e bonolo ea ho qala. , e le ho fokotsa tšusumetso ea ts'ebetso ea ho qala ho mokhanni.Yuniti ea ho khanna ea matla e qala ka ho lokisa motlakase oa mekhahlelo e meraro kapa oa motlakase ka potoloho ea mehato e meraro ea borokho bo felletseng ho fumana motlakase o tsamaisanang le ona.Enjene ea mekhahlelo e meraro e sa feleng ea magnet synchronous AC servo motor e tsamaisoa ke inverter ea voltage ea sinusoidal PWM ea mekhahlelo e meraro.Ts'ebetso eohle ea yuniti ea ho khanna matla e ka hlalosoa feela e le ts'ebetso ea AC-DC-AC.Potoloho e ka sehloohong ea AC-DC ke potoloho e sa laoleheng ea borokho e nang le mekhahlelo e meraro.
Ka ts'ebeliso e kholo ea sistimi ea servo, ts'ebeliso ea servo drive, servo drive debugging, tlhokomelo ea servo drive ke lihlooho tsa bohlokoa tsa tekheniki tsamaisong ea kajeno ea servo, bafani ba litšebeletso tse ngata tsa taolo ea indasteri mabapi le theknoloji ea servo drive ea lipatlisiso tse tebileng. .
Mokhanni oa Servo ke karolo ea bohlokoa ea taolo ea sejoale-joale ea motsamao, e sebelisoang haholo lirobotong tsa indasteri le litsing tsa mochini oa CNC le lisebelisoa tse ling tsa othomathike.Haholo-holo, mokhanni oa servo ea sebelisetsoang ho laola AC e sa feleng ea magnet synchronous motor e fetohile sebaka sa lipatlisiso lapeng le mose ho maoatle.Algorithm ea hajoale, lebelo, boemo ba 3 ba taolo e koetsoeng e thehiloeng ho taolo ea vector e sebelisoa haholo moralong oa mokhanni oa servo oa AC.Hore na moralo oa lebelo o koetsoeng ka har'a algorithm ena o utloahala kapa ha o na karolo ea bohlokoa tsamaisong eohle ea taolo ea servo, haholo ts'ebetsong ea taolo ea lebelo.
2. Servo driver:
E le karolo ea bohlokoa ea taolo ea sejoale-joale ea motsamao, e sebelisoa haholo lirobotong tsa indasteri le litsing tsa machining tsa CNC le lisebelisoa tse ling tsa othomathike.Haholo-holo, mokhanni oa servo ea sebelisetsoang ho laola AC e sa feleng ea magnet synchronous motor e fetohile sebaka sa lipatlisiso lapeng le mose ho maoatle.Algorithm ea hajoale, lebelo, boemo ba 3 ba taolo e koetsoeng e thehiloeng ho taolo ea vector e sebelisoa haholo moralong oa mokhanni oa servo oa AC.Hore na moralo oa lebelo o koetsoeng ka har'a algorithm ena o utloahala kapa ha o na karolo ea bohlokoa tsamaisong eohle ea taolo ea servo, haholo ts'ebetsong ea taolo ea lebelo.
Ka lebelo le koetsoeng la mokhanni oa servo, ho nepahala ha tekanyo ea lebelo la nako ea koloi ea rotor ho bohlokoa haholo ho ntlafatsa litšobotsi tse matla le tse tsitsitseng tsa taolo ea lebelo la loop ea lebelo.Bakeng sa ho fumana tekanyo lipakeng tsa ho nepahala ha tekanyo le litšenyehelo tsa sistimi, encoder e ntseng e eketseha ea photoelectric hangata e sebelisoa e le sensor ea ho metha lebelo, 'me mokhoa o tsamaisanang le lebelo ke M/T.Le hoja M / T tachometer e na le tekanyo e itseng ea ho lekanya le mefuta e mengata ea ho lekanya, e na le mefokolo ea eona ea tlhaho, ho kenyelletsa le: 1) bonyane palo e le 'ngoe e feletseng ea "disk pulse" e tlameha ho fumanoa nakong ea ho lekanya, e fokotsang lebelo le lekantsoeng le fokolang;2) Ho thata bakeng sa li-switch tsa timer tsa litsamaiso tse peli tsa taolo tse sebelisetsoang tekanyo ea lebelo ho boloka khokahano e tiileng, 'me ho nepahala ha tekanyo ea lebelo ho ke ke ha netefatsoa liketsahalong tsa ho lekanya ka liphetoho tse kholo tsa lebelo.Ka hona, ho thata ho ntlafatsa ts'ebetso ea lebelo la mokhanni oa servo le ho laola ka ho sebelisa mokhoa o tloaelehileng oa moralo oa loop.
Lintlha tse ling:
I. Sebaka sa kopo:
Servo drive e sebelisoa haholo tšimong ea mochini oa ho bopa ente, mochini oa masela, mochini oa ho paka, lisebelisoa tsa mochini oa CNC joalo-joalo.
Ii.Liphapang Tse Amanang:
1. Mookameli oa servo a ka fetola habonolo mochine oa ts'ebetso le mochini oa fieldbus ka sebopeho sa othomathike.Ka nako e ts'oanang, li-modules tse fapaneng tsa fieldbus li sebelisetsoa ho finyella mekhoa e fapaneng ea ho laola (RS232, RS485, fiber optical, InterBus, ProfiBus), 'me mokhoa oa ho laola oa converter frequency converter o batla o le mong.
2. Mookameli oa servo o amana ka ho toba le transformer ea rotary kapa encoder ho etsa sekhahla se koetsoeng sa lebelo le taolo ea ho falla.Empa universal frequency converter e ka theha sistimi e bulehileng ea taolo ea loop.
3. Lenane le leng le le leng la taolo (joalo ka ho nepahala ha boemo bo tsitsitseng le ts'ebetso e matla, joalo-joalo) ea servo controller e molemo ho feta ea converter frequency frequency.
