Sisitemu ya servo ikubiyemo moteri ya servo na moteri ya servo.Ikinyabiziga gikoresha ibitekerezo byuzuye bihujwe numuvuduko wihuse wibikoresho bya digitale DSP kugirango igenzure IGBT kugirango itange umusaruro usobanutse neza, ikoreshwa mugutwara ibyiciro bitatu bihoraho bya magnet bihoraho bihuza AC servo moteri kugirango igere kumikorere yihuse no kumikorere.Ugereranije na moteri isanzwe, disiki ya AC servo ifite ibikorwa byinshi byo kurinda imbere, kandi moteri ntizifite umuyonga hamwe nabagenzi, bityo akazi kizewe kandi imirimo yo kubungabunga no kuyitaho ni nto.
Kugirango wongere ubuzima bwakazi bwa sisitemu ya servo, ibibazo bikurikira bigomba kwitabwaho mugihe cyo gukoresha.Kubidukikije bikora bya sisitemu, ibintu bitanu byubushyuhe, ubushuhe, umukungugu, kunyeganyega hamwe n’umuvuduko winjiza bigomba kwitabwaho.Buri gihe usukure sisitemu yo gukwirakwiza no guhumeka ibikoresho bigenzura umubare.Buri gihe urebe niba abafana bakonje kubikoresho bigenzura imibare bakora neza.Igomba kugenzurwa no gusukurwa buri mezi atandatu cyangwa kimwe cya kane bitewe nibidukikije byamahugurwa.Iyo ibikoresho bya mashini ya CNC bidakoreshejwe igihe kinini, sisitemu ya CNC igomba kubungabungwa buri gihe.
Mbere ya byose, sisitemu ya CNC igomba gushyirwamo ingufu kenshi, kandi ikareka ikagenda nta mutwaro mugihe igikoresho cyimashini gifunze.Mugihe cyimvura iyo ubuhehere bwikirere buri hejuru, amashanyarazi agomba kuzimya burimunsi, kandi ubushyuhe bwibigize amashanyarazi ubwabyo bigomba gukoreshwa kugirango wirukane ubuhehere buri muri guverenema ya CNC kugirango habeho imikorere ihamye kandi yizewe ya ibikoresho bya elegitoroniki.Imyitozo yerekanye ko igikoresho cyimashini gikunze guhagarara kandi kidakoreshwa gikunze kunanirwa mugihe gifunguye nyuma yimvura.Bitewe nuburyo akazi gakoreshwa nabakoresha amaherezo ya sisitemu yo kugenzura ibyerekezo no kugabanuka kwubushobozi bwambere bwa tekinike yubuhanga bwa tekinike, sisitemu ya elegitoronike ntishobora kubona uburyo bwiza bwo gucunga ibikoresho, bishobora kugabanya igihe cyubuzima bwibikoresho bya mechatronics, cyangwa kugabanya ubushobozi bwo kubyaza umusaruro kubera kunanirwa ibikoresho.Gutakaza inyungu zubukungu.
Umushoferi wa Servo ni ubwoko bwumugenzuzi ukoreshwa mugucunga moteri ya servo.Imikorere yacyo isa niy'umuhinduzi wa frequency ukora kuri moteri isanzwe ya AC.Nigice cya sisitemu ya servo kandi ikoreshwa cyane cyane muri sisitemu yo hejuru.Mubisanzwe, moteri ya servo igenzurwa hakoreshejwe uburyo butatu bwimyanya, umuvuduko na torque kugirango ugere kuri sisitemu yohereza ibintu neza.Kugeza ubu ni ibicuruzwa byo mu rwego rwo hejuru byikoranabuhanga ryohereza.
Nigute ushobora kugerageza no gusana disiki ya servo?Dore uburyo bumwe:
1. Iyo oscilloscope yagenzuye ibyasohotse muri iki gihe ikurikirana, byagaragaye ko byose ari urusaku kandi bidashobora gusomwa;
Impamvu yamakosa: Ibisohoka byanyuma byo kugenzura ntabwo bitandukanijwe no gutanga amashanyarazi ya AC (transformateur).Igisubizo: Urashobora gukoresha voltmeter ya DC kugirango umenye kandi urebe.
2. Moteri ikora byihuse mu cyerekezo kimwe kuruta ikindi
Impamvu yo gutsindwa: Icyiciro cya moteri idafite brush iribeshya.Uburyo bwo gutunganya: gutahura cyangwa kumenya icyiciro gikwiye.
Impamvu yo gutsindwa: Iyo idakoreshejwe mugupimisha, ikizamini / gutandukana ni mumwanya wikizamini.Igisubizo: Hindura ikizamini / gutandukana kumwanya wo gutandukana.
Impamvu yo gutsindwa: Umwanya wo gutandukana potentiometero ntabwo aribyo.Uburyo bwo kuvura: gusubiramo.
3. Ahantu hahagarara
Impamvu yamakosa: polarite yibitekerezo byihuta nibeshya.
Uburyo:
a.Niba bishoboka, shiraho imyanya ibitekerezo polarite ihindure kurundi mwanya.(Birashoboka kuri drives zimwe)
b.Niba ukoresheje tachometero, hindura TACH + na TACH- kuri disiki kugirango uhuze.
c.Niba kodegisi ikoreshwa, hindura ENC A na ENC B kuri disiki.
d.Muburyo bwihuta bwa HALL, hindura HALL-1 na HALL-3 kuri disiki, hanyuma uhindure Motor-A na Motor-B.
Impamvu yamakosa: amashanyarazi ya encoder atangwa-ingufu iyo kodegisi yihuta.
Igisubizo: Reba ihuriro rya 5V encoder itanga amashanyarazi.Menya neza ko amashanyarazi ashobora gutanga amashanyarazi ahagije.Niba ukoresheje amashanyarazi yo hanze, menya neza ko voltage iri kubimenyetso bya shoferi.
4. Itara rya LED ni icyatsi, ariko moteri ntigenda
Impamvu yamakosa: moteri mucyerekezo kimwe cyangwa byinshi birabujijwe kugenda.
Igisubizo: Reba + INHIBIT na –INHIBIT ibyambu.
Impamvu yo kunanirwa: Ikimenyetso cyibimenyetso ntabwo kiri kubutaka bwibimenyetso.
