Nidaamka servo waxaa ka mid ah servo drive iyo servo motor.Wadadu waxay isticmaashaa jawaab celin sax ah oo ay weheliso processor-ka signalka dhijitaalka ah ee xawaarahiisu sareeyo ee DSP si loo xakameeyo IGBT si loo dhaliyo wax soo saarka hadda jira, kaas oo loo isticmaalo in lagu kaxeeyo saddexda weji ee magnetka joogtada ah ee AC servo motor si loo gaadho nidaaminta xawaaraha saxda ah iyo meelaynta shaqooyinka.Marka la barbar dhigo matoorada caadiga ah, AC servo drives waxay leeyihiin hawlo badan oo ilaalin ah oo gudaha ah, matooradana ma laha burush iyo matoorayaal, sidaa darteed shaqadu waa mid la isku halayn karo oo culayska shaqada dayactirka iyo dayactirku waa mid yar.
Si loo kordhiyo nolosha shaqada ee nidaamka servo, arrimaha soo socda waa in fiiro gaar ah loo yeesho inta lagu jiro isticmaalka.Deegaanka ka hawlgala nidaamka, shanta walxood ee heerkulka, qoyaanka, boodhka, gariirka iyo korantada gelinta ayaa loo baahan yahay in la tixgeliyo.Si joogto ah u nadiifi kuleylka kulaylka iyo nidaamka hawo-qaadista ee qalabka xakamaynta tirada.Had iyo jeer iska hubi in taageereyaasha qaboojinta ee aaladda kantaroolka tirooyinka ay si habboon u shaqaynayaan.Waa in la baaro oo la nadiifiyaa lixdii biloodba ama rubuckiiba iyadoo ku xiran jawiga aqoon isweydaarsiga.Marka qalabka mashiinka CNC aan la isticmaalin muddo dheer, nidaamka CNC waa in si joogto ah loo ilaaliyo.
Ugu horreyntii, nidaamka CNC waa in si joogto ah loo tamar-geliyo, oo ha u shaqeeyo iyada oo aan culeys lahayn marka qalabka mashiinka la xiro.Xilliga roobaadka ee qoyaanka hawadu uu sarreeyo, korontadu waa in la shideeyaa maalin kasta, kulaylka qaybaha korantada laftooda waa in loo adeegsadaa in laga saaro qoyaanka golaha CNC si loo hubiyo waxqabadka xasilloon oo la isku halleyn karo ee qaybaha elektarooniga ah.Tababarku waxa uu caddeeyey in mishiinada inta badan la dhigto oo aan la isticmaalin ay u nugul tahay cillado kala duwan marka la shido maalin roobaadka ka dib.Sababtoo ah xaaladaha shaqada ee isticmaalayaasha dhamaadka nidaamka xakamaynta dhaqdhaqaaqa iyo xaddidaadda awoodda taageerada farsamada ee ugu horreysa ee shirkadda, nidaamka elektiroonigga ah inta badan ma awoodo inuu helo maareynta qalabka wanaagsan, kaas oo soo gaabin kara wareegga nolosha ee qalabka mechatronics. ama la yareeyo awoodda wax soo saarka sababtoo ah cilladda qalabka.Luminta faa'iidooyinka dhaqaale.
Darawalka Servo waa nooc ka mid ah kontaroolayaasha loo isticmaalo in lagu xakameeyo matoorka servo.Shaqadeedu waxay la mid tahay beddelaha soo noqnoqda ee ku shaqeeya matoorka AC caadiga ah.Waa qayb ka mid ah nidaamka servo waxaana inta badan loo adeegsadaa nidaamka meelaynta saxda ah.Guud ahaan, matoorka servo waxaa lagu xakameeyaa iyada oo loo marayo saddex hab oo booska, xawaaraha iyo qulqulka si loo gaaro meelaynta nidaamka gudbinta saxda ah.Hadda waa wax soo saarka ugu sarreeya ee tignoolajiyada gudbinta.
Haddaba sidee loo tijaabiyaa oo loo dayactiraa servo drive?Waa kuwan hababka qaar:
1. Markii oscilloscope-ku uu hubiyay wax-soo-saarka la socodka hadda ee waduhu, waxa la ogaaday in uu dhammaan ahaa buuq oo aan la akhriyi karin.
Sababta cilladda: Terminalka wax-soo-saarka ee kormeerka hadda kamuu go'in sahayda AC (transformer).Xalka: Waxaad isticmaali kartaa voltmeter-ka DC si aad u ogaato oo u aragto.
2. Matoorku hal jiho ayuu uga dheereeyaa kan kale
Sababta fashilka: Marxaladda matoorka aan burushka lahayn waa khalad.Habka habaynta: ogow ama ogow marxaladda saxda ah.
Sababta guuldarada: Marka aan loo isticmaalin tijaabada, beddelka tijaabada/wareejinta ayaa ku jira booska tijaabada.Xalka: U rog tijaabada/wareejinta beddelka booska leexinta.
Sababta guuldarada: Booska potentiometer-ka leexashada waa khalad.Habka daawaynta: dib u habeyn
3. Meesha baabuurka
Sababta cilladda: kala-soocidda falcelinta xawaaraha waa khalad.
Habka:
a.Haddi ay suurtagal tahay, dhig booska jawaab celinta u beddelashada boos kale.(Waxaa suurtagal ah darawallada qaarkood)
b.Haddii aad isticmaalayso tachometer, ku beddel TACH+ iyo TACH- waditaanka si aad isugu xidho.
c.Haddii codeer la isticmaalo, ku beddel ENC A iyo ENC B dariiqa dhexdiisa.
d.Habka xawaaraha HALL, ku beddel HALL-1 iyo HALL-3 wadista, ka dibna ku beddel Motor-A iyo Motor-B.
Sababta cilada: sahayda korantada encoder-ku waa laga tamar-saaray marka cod-celinta xawaaraha-celinta.
Xalka: Hubi isku xirka sahayda korantada ee 5V.Hubi in korontadu ay bixin karto hadda ku filan.Haddii la isticmaalayo koronto dibadeed, iska hubi in danabku uu u jeedo dhulka calaamadda darawalka.
4. Ilaysku waa cagaar, laakiin matoorku ma dhaqaaqo
Sababta cilladda: matoorka hal jiho ama dhowr jiho waa mamnuuc inuu dhaqaaqo.
Xalka: Hubi + INHIBIT iyo -INHIBIT dekedaha.
Sababta guuldarada: Digniinta amarku maaha dhulka calaamadda wadista.
Habka habaynta: Ku xidh dhulka calaamadda amarka dhulka calaamadda darawalka.
5. Kadib marka la shido, nalka LED-ka darawalku ma shido
Sababta fashilantay: Danabka sahayda korantadu aad buu u hooseeyaa, in ka yar waxa loo baahan yahay danab.
Xalka: Hubi oo kordhi korantada sahayda.
6. Marka uu matoorku wareego, iftiinka LED-ku wuu shidaa
Sababta fashilka: Khaladka wajiga HALL.
Xalka: Hubi in beddelka habaynta wejiga mootada (60/120) uu sax yahay.Inta badan matoorada aan burushka lahayn waxay leeyihiin farqi weji ah oo ah 120°.
Sababta fashilantay: Dareemaha HALL oo guul daraystay
Xalka: Soo ogow tamarta Hall A, Hall B, iyo Hall C marka matoorku wareego.Qiimaha danabku waa inuu u dhexeeyaa 5VDC iyo 0.
7. Iftiinka LED had iyo jeer wuxuu hayaa casaan.Sababta fashilka: fashil ayaa jira.
Habka daaweynta: Sababta: koronto-dhaafka ah, koronto yar, wareegga gaaban, kulaylka, darawalka waa mamnuuc, HALL aan ansax ahayn.
