Dongosolo la servo limaphatikizapo servo drive ndi servo motor.Kuyendetsa kumagwiritsa ntchito mayankho olondola ophatikizidwa ndi purosesa yothamanga kwambiri ya digito ya DSP kuwongolera IGBT kuti ipange zotulutsa zenizeni, zomwe zimagwiritsidwa ntchito kuyendetsa magawo atatu okhazikika maginito synchronous AC servo motor kuti akwaniritse kuwongolera liwiro ndikuyika ntchito.Poyerekeza ndi ma motors wamba, ma AC servo drives ali ndi ntchito zambiri zoteteza mkati, ndipo ma motors alibe maburashi ndi ma commutators, motero ntchitoyo ndi yodalirika komanso ntchito yokonza ndi kukonza ndi yaying'ono.
Kuti mutalikitse moyo wantchito wa servo system, zinthu zotsatirazi ziyenera kuyang'aniridwa pakugwiritsa ntchito.Pamalo ogwiritsira ntchito makinawo, zinthu zisanu za kutentha, chinyezi, fumbi, kugwedezeka ndi magetsi olowera ziyenera kuganiziridwa.Nthawi zonse yeretsani kutentha kwa kutentha ndi mpweya wabwino wa chipangizo chowongolera manambala.Nthawi zonse fufuzani ngati mafani ozizira pa chipangizo chowongolera manambala akugwira ntchito moyenera.Iyenera kuyang'aniridwa ndi kuyeretsedwa miyezi isanu ndi umodzi kapena kotala iliyonse malinga ndi malo a msonkhanowo.Pamene CNC makina chida si ntchito kwa nthawi yaitali, dongosolo CNC ayenera kusamalidwa nthawi zonse.
Choyamba, dongosolo la CNC liyenera kupatsidwa mphamvu pafupipafupi, ndikulola kuti liziyenda popanda katundu pamene chida cha makina chatsekedwa.M'nyengo yamvula pamene chinyezi cha mpweya chimakhala chokwera kwambiri, magetsi ayenera kuyatsidwa tsiku ndi tsiku, ndipo kutentha kwa zigawo zamagetsi pawokha kuyenera kugwiritsidwa ntchito kuthamangitsa chinyezi mu nduna ya CNC kuti zitsimikizire kugwira ntchito kokhazikika komanso kodalirika kwa magetsi. zida zamagetsi.Zoyeserera zatsimikizira kuti chida cha makina chomwe nthawi zambiri chimayimitsidwa komanso chosagwiritsidwa ntchito chimakhala cholephera zosiyanasiyana chikayatsidwa pambuyo pa mvula.Chifukwa cha momwe amagwirira ntchito omaliza oyendetsa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake; kapena kuchepetsa mphamvu zopangira chifukwa cha kulephera kwa zida.Kutayika kwa phindu lachuma.
Dalaivala wa Servo ndi mtundu wa owongolera omwe amagwiritsidwa ntchito kuwongolera servo mota.Ntchito yake ndi yofanana ndi ya frequency converter yomwe imagwira pa mota wamba ya AC.Ndi gawo la servo system ndipo imagwiritsidwa ntchito makamaka pamakina apamwamba kwambiri.Nthawi zambiri, injini ya servo imayendetsedwa kudzera munjira zitatu za malo, liwiro ndi torque kuti ikwaniritse mawonekedwe apamwamba kwambiri.Pakalipano ndi mankhwala apamwamba a teknoloji yopatsirana.
Ndiye mungayese bwanji ndikukonza servo drive?Nazi njira zina:
1. Pamene oscilloscope adayang'ana zomwe zikuchitika panopa pa galimotoyo, adapeza kuti zonse zinali phokoso ndipo sizingawerengedwe.
Choyambitsa cholakwika: Choyimira chotuluka pakuwunika kwapano sichimalekanitsidwa ndi magetsi a AC (transformer).Yankho: Mutha kugwiritsa ntchito voltmeter ya DC kuti muwone ndikuwona.
2. Galimoto imathamanga kwambiri mbali imodzi kuposa ina
Choyambitsa cholephera: Gawo la mota ya brushless ndilolakwika.Njira yopangira: pezani kapena pezani gawo lolondola.
Choyambitsa cholephera: Ikapanda kugwiritsidwa ntchito poyesa, chosinthira choyesa/kupatuka chili pamalo oyeserera.Yankho: Sinthani chosinthira choyesa / kupatuka kuti chikhale chopatuka.
Chifukwa cholephera: Malo a potentiometer yopatuka ndi olakwika.Njira yothandizira: bwererani.
3. Malo ogulitsira magalimoto
Chifukwa cha cholakwika: polarity ya liwiro mayankho ndi zolakwika.
Njira:
a.Ngati n'kotheka, ikani kusintha kwa polarity kwa malowo kupita kumalo ena.(Ndizotheka pama drive ena)
b.Ngati mukugwiritsa ntchito tachometer, sinthanani TACH+ ndi TACH- pagalimoto kuti mulumikizane.
c.Ngati chosindikiza chikugwiritsidwa ntchito, sinthanani ENC A ndi ENC B pagalimoto.
d.Mumayendedwe othamanga a HALL, sinthanani HALL-1 ndi HALL-3 pagalimoto, kenako sinthani Motor-A ndi Motor-B.
Choyambitsa cholakwikacho: mphamvu ya encoder imachotsedwa mphamvu pomwe encoder imayankha mwachangu.
Yankho: Yang'anani kulumikizidwa kwa magetsi a 5V encoder.Onetsetsani kuti magetsi angapereke zokwanira panopa.Ngati mukugwiritsa ntchito magetsi akunja, onetsetsani kuti voliyumuyo ili pamtunda wamakina oyendetsa.
4. Kuwala kwa LED ndi kobiriwira, koma galimoto sikuyenda
Chifukwa cha cholakwika: mota munjira imodzi kapena zingapo ndizoletsedwa kusuntha.
Yankho: Chongani +INHIBIT ndi -INHIBIT madoko.
Chifukwa cholephera: Chizindikiro cholamula sichili pamalo opangira ma drive.
Njira yopangira: Lumikizani malo olumikizirana ndi oyendetsa.
5. Pambuyo pamagetsi, kuwala kwa LED kwa dalaivala sikuyatsa
Choyambitsa chalephereka: Mphamvu yamagetsi ndiyotsika kwambiri, yocheperako poyerekeza ndi zomwe zimafunikira.
Yankho: Yang'anani ndikuwonjezera mphamvu yamagetsi.
6. Pamene injini ikuzungulira, kuwala kwa LED kumawala
Chifukwa cholephera: cholakwika cha gawo la HALL.
Yankho: Onani ngati kusintha kwa gawo la mota (60/120) ndikolondola.Ma motors ambiri opanda burashi ali ndi kusiyana kwa gawo la 120 °.
Chifukwa cholephera: HALL sensor kulephera
Yankho: Dziwani ma voltages a Hall A, Hall B, ndi Hall C pomwe injini ikuzungulira.Mphamvu yamagetsi iyenera kukhala pakati pa 5VDC ndi 0.
7. Kuwala kwa LED kumakhala kofiira nthawi zonse.Chifukwa chalephereka: Pali kulephera.
Njira yothandizira: Chifukwa: overvoltage, undervoltage, short circuit, overheating, dalaivala woletsedwa, HALL yosavomerezeka.
