Tsarin servo ya haɗa da servo drive da motar servo.Motar tana amfani da madaidaicin martani da aka haɗa tare da na'ura mai sarrafa siginar dijital mai sauri DSP don sarrafa IGBT don samar da daidaitaccen fitarwa na yanzu, wanda ake amfani da shi don fitar da injin maganadisu na dindindin guda uku na AC servo motor don cimma daidaitaccen tsarin saurin gudu da ayyukan sakawa.Idan aka kwatanta da na'urori na yau da kullun, injin AC servo yana da ayyukan kariya da yawa a ciki, kuma injinan ba su da goge-goge da masu zirga-zirga, don haka aikin abin dogaro ne kuma aikin kulawa da kulawa yana da ɗan ƙaramin ƙarfi.
Don tsawaita rayuwar aiki na tsarin servo, ya kamata a kula da batutuwa masu zuwa yayin amfani.Don yanayin aiki na tsarin, ana buƙatar la'akari da abubuwa biyar na zafin jiki, zafi, ƙura, girgizawa da ƙarfin shigarwa.A kai a kai tsaftace tsattsauran zafin jiki da tsarin samun iska na na'urar sarrafa lamba.Koyaushe bincika ko magoya bayan sanyaya akan na'urar sarrafa lamba suna aiki da kyau.Ya kamata a duba tare da tsaftace shi kowane wata shida ko kwata ya danganta da yanayin taron.Lokacin da ba a yi amfani da kayan aikin CNC na dogon lokaci ba, tsarin CNC ya kamata a kiyaye shi akai-akai.
Da farko dai, tsarin CNC ya kamata a ba da kuzari akai-akai, kuma a bar shi ya gudana ba tare da kaya ba lokacin da aka kulle na'urar.A lokacin damina, lokacin da zafi ya yi yawa, yakamata a kunna wutar lantarki a kowace rana, sannan a yi amfani da zafin na'urorin lantarki da kansu don fitar da danshi a cikin majalisar CNC don tabbatar da ingantaccen aiki mai aminci da aminci. kayan lantarki.Kwararru sun tabbatar da cewa na'urar da ake ajiyewa a lokuta da yawa kuma ba a yi amfani da ita ba tana da saurin lalacewa iri-iri idan aka kunna ta bayan ruwan sama.Saboda yanayin aiki na ƙarshen masu amfani da tsarin kula da motsi da kuma iyakancewar ikon tallafin fasaha na injiniya na farko na kamfanin, tsarin lantarki na lantarki sau da yawa ya kasa samun kyakkyawan tsarin sarrafa kayan aiki, wanda zai iya rage tsawon rayuwar kayan aikin mechatronics. ko rage ƙarfin samarwa saboda gazawar kayan aiki.Asarar fa'idojin tattalin arziki.
Direban Servo wani nau'in sarrafawa ne da ake amfani dashi don sarrafa motar servo.Ayyukansa yayi kama da na mai sauya mitar mai aiki akan injin AC na yau da kullun.Yana da wani ɓangare na tsarin servo kuma ana amfani dashi da yawa a cikin madaidaicin tsarin sakawa.Gabaɗaya, ana sarrafa motar servo ta hanyoyi guda uku na matsayi, saurin gudu da juzu'i don cimma daidaiton tsarin tsarin watsawa.A halin yanzu babban samfuri ne na fasahar watsawa.
Don haka yadda za a gwada da gyara servo drive?Ga wasu hanyoyin:
1. Lokacin da oscilloscope ya duba kayan sa ido na yanzu na tuƙi, an gano cewa duk hayaniya ne kuma ba za a iya karantawa ba.
Dalilin kuskuren: Tashar tashar fitarwa na saka idanu na yanzu ba ta keɓanta da wutar lantarki ta AC (transformer).Magani: Zaka iya amfani da voltmeter na DC don ganowa da lura.
2. Motar tana tafiyar da sauri a hanya ɗaya fiye da ɗayan
Dalilin gazawar: Matsayin injin da ba shi da gogewa ba daidai ba ne.Hanyar sarrafawa: gano ko gano madaidaicin lokaci.
Dalilin gazawar: Lokacin da ba a yi amfani da shi don gwaji ba, gwajin gwajin / juzu'i yana cikin matsayin gwaji.Magani: Juya gwajin gwaji/bangaɗi zuwa matsayi karkata.
Dalilin gazawar: Matsayin karkatacciyar potentiometer ba daidai ba ne.Hanyar magani: sake saiti.
3. Wurin mota
Dalilin laifin: polarity na amsawar saurin ba daidai ba ne.
Hanyar:
a.Idan za ta yiwu, saita canjin ra'ayi na matsayi zuwa wani matsayi.(Yana yiwuwa akan wasu tukwici)
b.Idan amfani da tachometer, musanya TACH+ da TACH- akan tuƙi don haɗawa.
c.Idan an yi amfani da maɓalli, musanya ENC A da ENC B akan tuƙi.
d.A cikin yanayin gudun HALL, musanya HALL-1 da HALL-3 akan tuƙi, sannan musanya Motoci-A da Motar-B.
Dalilin kuskuren: na'urar shigar da wutar lantarki ba ta da ƙarfi lokacin da saurin amsawa.
Magani: Duba haɗin haɗin wutar lantarki na 5V.Tabbatar cewa wutar lantarki na iya samar da isasshiyar halin yanzu.Idan ana amfani da wutar lantarki ta waje, tabbatar cewa ƙarfin lantarki yana zuwa ƙasan siginar direba.
4. Hasken LED kore ne, amma motar ba ta motsawa
Dalilin laifin: motar a daya ko fiye da kwatance an hana motsi.
Magani: Duba + INHIBIT da –INHIBIT tashoshin jiragen ruwa.
Dalilin gazawa: Siginar umarni ba zuwa ƙasan siginar tuƙi ba.
Hanyar sarrafawa: Haɗa ƙasa siginar umarni zuwa ƙasan siginar direba.
5. Bayan kunnawa, hasken LED ɗin direba ba ya haskakawa
Dalilin gazawar: Wutar wutar lantarki ya yi ƙasa da ƙasa da mafi ƙarancin ƙarfin lantarki da ake buƙata.
Magani: Duba kuma ƙara ƙarfin wutar lantarki.
6. Lokacin da motar ta juya, hasken LED yana haskakawa
Dalilan gazawa: Kuskuren lokacin ZAURE.
Magani: Bincika ko canjin saitin lokaci na motar (60/120) daidai ne.Yawancin injina marasa gogewa suna da bambancin lokaci na 120°.
Dalilin gazawa: gazawar firikwensin HALL
Magani: Gano ƙarfin lantarki na Hall A, Hall B, da Hall C lokacin da motar ke juyawa.Ya kamata darajar wutar lantarki ta kasance tsakanin 5VDC da 0.
7. Hasken LED koyaushe yana kiyaye ja.Dalilin gazawa: Akwai gazawa.
Hanyar magani: Dalili: overvoltage, rashin ƙarfi, gajeriyar kewayawa, zafi fiye da kima, an haramta direba, HALL mara inganci.
