Uhlelo lwe-servo luhlanganisa i-servo drive kanye ne-servo motor.Idrayivu isebenzisa impendulo enembayo ehlanganiswe neprosesa yesignali yedijithali enesivinini esikhulu i-DSP ukuze ilawule i-IGBT ukuze ikhiqize okukhiphayo okunembayo kwamanje, okusetshenziselwa ukushayela injini ye-AC servo motor yezigaba ezintathu ezihlala unomphela uzibuthe ukuze kuzuzwe ukulawulwa kwejubane okunembe kanye nemisebenzi yokubeka indawo.Uma kuqhathaniswa namamotho ajwayelekile, amadrayivu e-AC servo anemisebenzi eminingi yokuvikela ngaphakathi, futhi izinjini azinawo amabhulashi nabagibeli, ngakho-ke umsebenzi unokwethenjelwa futhi umthwalo wokunakekela nowokulungisa mncane uma kuqhathaniswa.
Ukuze kunwetshwe impilo yokusebenza yesistimu ye-servo, lezi zinkinga ezilandelayo kufanele zinakwe ngesikhathi sokusetshenziswa.Ngendawo yokusebenza yesistimu, izakhi ezinhlanu zamazinga okushisa, umswakama, uthuli, ukudlidliza kanye ne-voltage yokufaka zidinga ukucatshangelwa.Hlanza njalo ukukhishwa kokushisa kanye nesistimu yokungenisa umoya yedivayisi yokulawula izinombolo.Ngaso sonke isikhathi hlola ukuthi amafeni okupholisa edivayisini yokulawula izinombolo asebenza kahle yini.Kufanele ihlolwe futhi ihlanzwe njalo ezinyangeni eziyisithupha noma ikota kuye ngendawo yendawo yokusebenzela.Uma ithuluzi lomshini we-CNC lingasetshenziswa isikhathi eside, uhlelo lwe-CNC kufanele lugcinwe njalo.
Okokuqala, uhlelo lwe-CNC kufanele lunikezwe amandla njalo, futhi luvumele lusebenze ngaphandle komthwalo lapho ithuluzi lomshini likhiyiwe.Ngenkathi yemvula lapho umswakama womoya uphakeme kakhulu, ugesi kufanele uvulelwe nsuku zonke, futhi ukushisa kwezingxenye zikagesi ngokwazo kufanele kusetshenziselwe ukuxosha umswakama ekhabhinethi ye-CNC ukuze kuqinisekiswe ukusebenza okuzinzile nokuthembekile kwe-CNC. izingxenye ze-elekthronikhi.Ukuzijwayeza kufakazele ukuthi ithuluzi lomshini elivame ukupakwa futhi elingasetshenziswa lijwayele ukwehluleka okuhlukahlukene lapho livuliwe ngemva kosuku lwemvula.Ngenxa yezimo zokusebenza zabasebenzisi bokugcina besistimu yokulawula ukunyakaza kanye nomkhawulo wamakhono wokusekelwa kobuchwepheshe bomugqa wokuqala wenkampani, uhlelo lwe-electromechanical ngokuvamile alukwazi ukuthola ukuphathwa kahle kwemishini, okunganciphisa umjikelezo wempilo wemishini ye-mechatronics, noma ukunciphisa umthamo wokukhiqiza ngenxa yokwehluleka kwemishini.Ukulahlekelwa izinzuzo zomnotho.
Umshayeli we-Servo wuhlobo lwesilawuli esisetshenziselwa ukulawula i-servo motor.Umsebenzi wayo uyafana nowokuguqulela imvamisa osebenza kumotho eyejwayelekile ye-AC.Iyingxenye yesistimu ye-servo futhi isetshenziswa kakhulu ohlelweni lokumisa olunembe kakhulu.Ngokuvamile, i-servo motor ilawulwa ngezindlela ezintathu zokuma, isivinini kanye ne-torque ukuze kuzuzwe ukuma kwesistimu yokudlulisa ngokunemba okuphezulu.Njengamanje iwumkhiqizo osezingeni eliphezulu wobuchwepheshe bokudlulisa.
Ngakho-ke ungayihlola kanjani futhi ulungise i-servo drive?Nazi ezinye izindlela:
1. Lapho i-oscilloscope ihlola ukukhishwa kokuqapha kwamanje kwedrayivu, kwatholakala ukuthi wonke umsindo futhi wawungakwazi ukufundwa.
Imbangela yephutha: Itheminali yokukhiphayo yokuqapha yamanje ayihlukanisiwe kumthombo wamandla we-AC (i-transformer).Isixazululo: Ungasebenzisa i-voltmeter ye-DC ukuthola nokubheka.
2. Injini igijima ngokushesha ibheke kolunye uhlangothi kunolunye
Imbangela yokwehluleka: Isigaba se-brushless motor asilungile.Indlela yokucubungula: thola noma thola isigaba esifanele.
Imbangela yokwehluleka: Uma ingasetshenziselwa ukuhlola, iswishi yokuhlola/yephambuka isendaweni yokuhlola.Isixazululo: Guqula iswishi yokuhlola/yechezu iye endaweni yokuchezuka.
Imbangela yokwehluleka: Indawo ye-potentiometer yokuchezuka ayilungile.Indlela yokwelapha: setha kabusha.
3. Isitolo sezimoto
Isizathu sephutha: i-polarity yempendulo yesivinini ayilungile.
Indlela:
a.Uma kungenzeka, setha ukushintsha kwe-polarity yesikhundla uye kwenye indawo.(Kuyenzeka kwamanye amadrayivu)
b.Uma usebenzisa i-tachometer, shintsha i-TACH+ ne-TACH- kudrayivu ukuze uxhume.
c.Uma kusetshenziswa isifaki khodi, shintshanisa i-ENC A ne-ENC B kudrayivu.
d.Kumodi yesivinini ye-HALL, shintshanisa i-HALL-1 ne-HALL-3 kudrayivu, bese ushintshanisa i-Motor-A ne-Motor-B.
Imbangela yephutha: ukunikezwa kwamandla kwesifaki khodi kukhishwa amandla uma impendulo yesivinini sesifaki khodi.
Isixazululo: Hlola ukuxhunywa kwamandla kagesi wesifaki khodi esingu-5V.Qinisekisa ukuthi ukunikezwa kwamandla kunganikeza isimanje esanele.Uma usebenzisa amandla angaphandle, qiniseka ukuthi i-voltage isendaweni yesignali yomshayeli.
4. Isibani se-LED siluhlaza, kodwa injini ayinyakazi
Isizathu sephutha: injini endaweni eyodwa noma ngaphezulu ayivunyelwe ukuhamba.
Isixazululo: Hlola +INHIBIT kanye nezimbobo ze-INHIBIT.
Isizathu sokwehluleka: Isignali yomyalo ayikho endaweni yesiginali yedrayivu.
Indlela yokucubungula: Xhuma indawo yesiginali yomyalo endaweni yesignali yomshayeli.
5. Ngemva kokukhanyisa, isibani se-LED somshayeli asikhanyi
Imbangela yokwehluleka: I-voltage yokuphakelwa kwamandla iphansi kakhulu, ingaphansi kwemfuneko encane kagesi.
Isixazululo: Hlola futhi ukhuphule i-voltage yokuphakelwa kwamandla.
6. Lapho injini ijikeleza, ukukhanya kwe-LED kuyaphazima
Isizathu sokwehluleka: Iphutha lesigaba se-HALL.
Isixazululo: Hlola ukuthi iswishi yokusethwa kwesigaba semoto (60/120) ilungile yini.Amamotho amaningi angenabhulashi anomehluko wesigaba ongu-120°.
Isizathu sokwehluleka: Ukwehluleka kwenzwa ye-HALL
Isixazululo: Thola ama-voltage eHholo A, Ihholo B, neHholo C lapho injini izungeza.Inani lamandla kagesi kufanele libe phakathi kuka-5VDC no-0.
7. Isibani se-LED sihlala sibomvu.Imbangela yokwehluleka: Kukhona ukwehluleka.
Indlela yokwelapha: Isizathu: i-overvoltage, undervoltage, isifunda esifushane, ukushisa ngokweqile, umshayeli unqatshelwe, IHOLO alivumelekile.
