Pele re bua ka bothata bona, pele ho tsohle, re lokela ho hlaka ka sepheo sa servo motor, e amanang le koloi e tloaelehileng, servo motor e sebelisoa haholo bakeng sa boemo bo nepahetseng, kahoo hangata re re servo ea taolo, ha e le hantle, ke eona taolo ea boemo ba servo motor.Ha e le hantle, servo motor e boetse e sebelisa mekhoa e meng e 'meli ea ts'ebetso, ke hore, ho laola lebelo le ho laola torque, empa kopo e fokotsehile.Taolo ea lebelo ka kakaretso e lemohuoa ka frequency converter.Taolo ea lebelo e nang le servo motor hangata e sebelisoa bakeng sa ho potlakisa le ho theola lebelo kapa ho laola lebelo le nepahetseng, hobane ha e bapisoa le converter ea maqhubu, koloi ea servo e ka fihlela liphetohelo tse likete ka har'a limilimithara tse 'maloa.
Hobane servo e koetsoe-loop, lebelo le tsitsitse haholo.Taolo ea torque haholo-holo ke ho laola torque e hlahisoang ke enjene ea servo, hape ka lebaka la karabelo e potlakileng ea enjene ea servo.Ts'ebeliso ea mefuta e 'meli e kaholimo ea taolo, o ka nka servo drive joalo ka converter ea frequency, ka kakaretso e nang le taolo ea analog.
Ts'ebeliso ea mantlha ea servo motor kapa taolo ea maemo, kahoo pampiri ena e shebana le taolo ea boemo ba PLC ea servo motor.Taolo ea boemo e na le likarolo tse peli tsa 'mele tse hlokang ho laoloa, ke hore, lebelo le boemo.Ka ho khetheha, ke ho laola hore na koloi ea servo e fihla kapele hakae moo e leng teng le ho emisa ka nepo.
Mokhanni oa servo o laola sebaka le lebelo la koloi ea servo ka makhetlo a mangata le palo ea maqhubu ao a a fumanang.Ka mohlala, re ile ra lumellana hore motlakase oa servo o tla fetola maqhubu a mang le a mang a 10,000.Haeba PLC e romella li-pulse tsa 10,000 ka motsotso, joale motlakase oa servo o tlatsa selikalikoe ho 1r / min, 'me haeba o romela li-pulse tsa 10,000 ka motsotsoana, joale motlakase oa servo o tlatsa selikalikoe ho 60r / min.
Ka hona, PLC ke ka ho laola pulse ho laola servo motor, mokhoa oa 'mele oa ho romela pulse, ke hore, tšebeliso ea PLC transistor output ke mokhoa o sebelisoang ka ho fetisisa, hangata ke PLC e tlaase e sebelisang mokhoa ona.'Me PLC ea bohareng le e phahameng ke ho buisana ka palo le makhetlo a mangata a pulse ho mokhanni oa servo, joalo ka Profibus-DP CANopen,MECHATROLINK-II,EtherCAT joalo-joalo.Mekhoa ena e 'meli ke liteishene tse fapaneng tsa ts'ebetsong, moelelo oa ts'oana, bakeng sa lenaneo, oa tšoana.Ntle le ho amohela pulse, taolo ea servo drive e ts'oana hantle le ea inverter.
Bakeng sa ho ngola lenaneo, phapang ena e kholo haholo, Japanese PLC ke ho sebelisa mokhoa oa ho ruta, 'me European PLC ke ho sebelisa mokhoa oa li-blocks tse sebetsang.Empa moelelo oa ts'oana, joalo ka ho laola servo ho ea maemong a felletseng, o hloka ho laola mocha oa tlhahiso ea PLC, nomoro ea pulse, frequency ea pulse, ho potlakisa le ho theola nako, mme o hloka ho tseba hore na boemo ba mokhanni oa servo bo felile neng. , hore na ho fihlela moeli joalo-joalo.Ho sa tsotelehe hore na PLC ea mofuta ofe, ha se letho ho feta taolo ea bongata bona ba 'mele le ho bala li-parameter tsa motsamao, empa mekhoa e fapaneng ea ts'ebetso ea PLC ha e tšoane.
Tse kaholimo ke kakaretso ea PLC (programmable controller) control servo motor, ebe re utloisisa ho kengoa ha mehato ea ts'ireletso ea taolo ea PLC.
Taolo ea lenaneo la PLC e 'nile ea sebelisoa haholo likarolong tse fapa-fapaneng, hobane ka hare ho eona ho na le likarolo tse ngata tsa elektroniki, tse bonolo ho angoa ke tšitiso ea likarolo tse ling tsa motlakase, matla a khoheli a matla a motlakase, mocheso o teng le mongobo, amplitude ea vibration le lintlha tse ling. ama mosebetsi o tloaelehileng oa molaoli oa PLC, hangata sena se hlokomolohuoa ke batho ba bangata.Esita le haeba lenaneo le le molemo, ho ea ka sehokelo sa ho kenya ha se ele hloko, ka mor'a ho lokisa liphoso, ho matha ho tla tlisa liphoso tse ngata.Ke ntse ke matha hohle ke leka ho e hlokomela.
Lintlha tse latelang ke litemoso bakeng sa ho instola:
1. tikoloho ea ho kenya PLC
a, mocheso oa tikoloho o tloha ho 0 ho isa ho 55 degrees.Haeba mocheso o phahame haholo kapa o le tlase haholo, likarolo tsa motlakase tse ka hare li ke ke tsa sebetsa hantle.Nka mehato ea ho pholisa kapa ea ho futhumala ha ho hlokahala
b, mongobo o teng ke 35% ~ 85%, mongobo o phahame haholo, conductivity ea motlakase ea likarolo tsa elektronike e matlafatsoa, ho bonolo ho fokotsa motlakase oa likarolo, hona joale o moholo haholo le tšenyo ea ho senya.
c, e ke ke ea kenngoa ka maqhubu a vibration ea 50Hz, amplitude e feta 0.5mm, hobane amplitude ea vibration e kholo haholo, e fellang ka hore boto ea potoloho e ka hare ea likarolo tsa elektronike e chese.
d, ka hare le ka ntle ho lebokose la motlakase e lokela ho ba ka hohle kamoo ho ka khonehang hole le matla a khoheli le matla a motlakase (joaloka motlakase oa ho laola, matla a maholo a AC contactor, capacitor e kholo, joalo-joalo) likarolo tsa motlakase, 'me ho bonolo ho hlahisa li-harmonic tse phahameng. (joaloka frequency converter, servo driver, inverter, thyristor, joalo-joalo) lisebelisoa tsa ho laola.
e, qoba ho laela libakeng tse nang le lerōle la tšepe, kutu, khase e tukang, mongobo, joalo-joalo
f, ho molemo ho beha likarolo tsa motlakase karolong e ka holimo ea lebokose la motlakase, hole le mohloli oa mocheso, 'me u nahane ka phekolo ea ho pholile le ea ka ntle ea moea ha ho hlokahala.
2. Phepelo ea matla
a, ho fihlella ka nepo phepelo ea motlakase ea PLC, ho na le lintlha tse amanang ka kotloloho.Joalo ka Mitsubishi PLC DC24V;AC voltage ke mokhoa o feto-fetohang haholoanyane, mefuta e fapaneng ke 100V ~ 240V (e lumelloa ho fapana 85 ~ 264), maqhubu ke 50 / 60Hz, ha ho hlokahale hore u hule switch.Ho molemo ho sebelisa sesebelisoa sa ho itšehla thajana ho fana ka matla a PLC.
b, bakeng sa tlhahiso ea PLC DC24V hangata e sebelisoa bakeng sa phepelo ea motlakase ea mojule oa ts'ebetso e atolositsoeng, phepelo ea motlakase ea sensor ea terata e ka ntle ea terata e meraro kapa merero e meng, leha phepelo ea motlakase ea DC24V e na le lisebelisoa tse ngata tsa ts'ireletso le tsa nako e khuts'oane le bokhoni bo fokolang.Ho kgothaletswa hore sensor e ka ntle ea terata e meraro e sebelise motlakase o ikemetseng oa ho fetola matla ho thibela potoloho e khutšoanyane, e ka bakang tšenyo ea PLC le ho baka mathata a sa hlokahaleng.
3. Wiring le tataiso
Ha wiring, e lokela ho ts'oaroa ka letlapa la khatiso le batang ebe e hokahanngoa le liteishene tsa ho kenya le ho tsoa tsa PLC.E lokela ho ba e tiileng le e sireletsehileng.
Ha ho kenya letsoho ke lets'oao la DC, joalo ka mehloli ea tšitiso e potolohileng le tse ling, e lokela ho nahana ka thapo e sirelelitsoeng kapa para e sothehileng, tataiso ea inthaneteng ha ea lokela ho bapa le mohala oa motlakase mme e ke ke ea beoa ka har'a sekotjana se le seng, mohala oa mohala, ho thibela tshitiso.
4. Fatše
Ho hanyetsa ha mobu ha hoa lokela ho ba kholo ho feta 100 Ohms.Haeba ho na le sebaka sa fatše ka lebokoseng la motlakase, se kopanye ka ho toba ho bareng ea fatše.Se ke oa e hokela ho ground bar ka mor'a ho e hokela ho ground bar ea li-controller tse ling (tse kang frequency converters).
5. Ba bang
a, PLC e ke ke ea e-ba e otlolohileng, e otlolohileng ho ea ka ho kenya, joalo ka PLC e tiisa, ho latela ho kenngoa ha li-screw ho tiisa, eseng ho lokoloha, haeba ho sisinyeha, ho senyeha ha likarolo tsa ka hare tsa elektroniki, haeba seporo sa karete, se tlameha. khetha seporo sa karete se tšoanelehang, qala ho hula senotlolo ebe u kena seporong sa karete, ebe u sutumelletsa senotlolo, kamora hore molaoli oa PLC a se khone ho ea holimo le tlase.
b, haeba mofuta oa tlhahiso ea relay, ntlha ea eona ea tlhahiso ea hona joale ke 2A, kahoo ka mojaro o moholo (joalo ka DC clutch, valve solenoid), le haeba hona joale e le ka tlase ho 2A, e lokela ho nahana ka ho sebelisa phetoho ea relay.
