Servo System Xaiv Kev Xaiv Tsa
Muaj ntau ntau yam uas peb yuav tsum xav txog thaum xaiv txoj cai servo rau ib daim ntawv thov.Yuav kom ua tiav qhov kev ua tau zoo tshaj plaws ntawm tag nrho kev pabcuam, muaj 9 yam yuav tsum tau xav txog.
1.Qhov kev xaiv ntawm lub cev muaj zog
Thaum lub cav pib, nws muaj 3 yam tseem ceeb tshaj plaws: kev ceev, lub zog thiab teb inertia.
Thawj ob txoj cai yog cov cuab yeej, thiab feem ntau, suav nrog tau siv "lub sam xeeb" software uas muab los ntawm lub khw.
Thaum siv cov kev pabcuam no, nkag mus rau hom kev tawm suab hauv daim ntawv thov thiab tus software yuav suav cov nyiaj uas yuav tsum tau ua kom muaj zog thiab ceev raws li hom kev thauj thiab tsav (gearbox, siv, khib thiab pinion, pob ntsia hlau, thiab lwm yam). Thaum lub inertia teb tsis yog intuitive, nws yog ib qho tseem ceeb sib npaug.Vim muaj ntau lub coupling yog txuas nrog nws cov kev sib txuas ntawm txhua yam txuas, nws yog qhov tseem ceeb uas lub cav tov teb inertia piv rau lub load reflex inertial tsis dhau loj.
Raws li qhov kev faib ua feem ntawm ob qhov nce, nws yuav ua rau ib qho tseem ceeb nce ntawm kev nyuaj ntawm kev hloov.Lwm cov kev cai algorithms evolve, microprocessor ceev nce thiab tso cai piv nce, tab sis cov tsoos 10: 1 load-motor inertia piv yog kev xaiv zoo.
2.Load txuas
Yuav tsum muaj lub cav txuas nrog ncaj qha? Qee servo khoom pub rau cov khoom thauj mus txuas ncaj nraim mus rau lub cev muaj zog rotor. Qhov tsawg kawg ntawm kev ua raws thiab kev nce qib qis / qhov qis, tus nqi zog ntawm tus tshaj 100: 1 tuaj yeem ua tiav.Qhov kev xaiv software uas muab los ntawm lub khw yog qhov zoo tshaj plaws los tsim kho cov qauv txheej txheem no kom txo tau qhov system txoj kev hloov mus rau ib theem.
3. Siv dua hluav taws xob
Lwm qhov tseem ceeb uas servo systems yuav tsum tau xav txog hauv ntau daim ntaub ntawv yog kev muaj peev xwm los tswj tau lub zog uas siv tau los ntawm cov khoom siv thiab cov khoom siv hluav taws xob los ntawm cov khoom siv. , lub cav yuav xa cov hluav taws xob rov qab mus rau lub tshuab nqus hluav taws xob.Qhov no yog vim cov qauv tsim ntawm lub tshuab yog tib yam li cov khoom siv hluav taws xob.
Lub zog xa mus rau lub cev qij, yuav tsim hluav taws xob rotor thiab tas li cov hlau nplaum yuav ua raws li tig tau rov qab.Yog li, thaum lub tshuab rotor rotates, cov hlau nplaum zog ua haujlwm kom cov cua ntsawj ntshab. Muaj ntau ntau txoj kev tsav tsheb los siv txuas dua tshiab zog.Tej me me tsav tsheb siv lub npav cov neeg tsav tsheb mus nqus cov hluav taws xob no, thiab tus tsav tsheb loj dua qub no siv hluav taws xob nrog kev ua haujlwm hauv tsev ua haujlwm.Qhov kev xaiv software muab los ntawm lub tuam txhab feem ntau muab cov txheej txheem hluav taws xob.
4. Cuam tshuam kev hloov tshiab
Rau qee lub tshuab loj feem ntau nruab nrog converters, yog li ntawd lub zog yuav kis tau rov qab mus rau qhov system fais mov circuit.Lwm yam yuav tsum tau xav tias thaum tsim ib qhov system servo yog tus nqi ntawm regenerative zog uas tsav tau lis yog tsim pub rau inertia mismatch ntawm lub cav thiab lub load.
Sab nraud fais fab tiv taus yog feem ntau txuas nrog lub amplifier thaum kov ntau daim ntawv thov hluav taws xob.Thaum lub ntiajteb txawj nqus
yuav yog ib qho tseem ceeb ntawm kev txhawj xeeb, thiab xav tau kom txo cov kev hloov loj hauv kev loj, cov ntawv sau npe no feem ntau vertically oriented.
Obviously, ntxiv rau lub zog regenerative, lub amplifier tseem xav tau muab lub cav nrog kom muaj qhov muaj zog thiab tam sim no mus cuag qhov kev xav tau ceev thiab lub zog.Xaiv lub hwjchim uas yuav tsum tau ua rau cov motors thiab amplifiers yog qhov pib xwb.
5.Txoj kev tswj cov cai
Tom ntej no, peb yuav tsum tau tswj qhov kev xav tswj.Let's rov qab mus rau lub cev muaj zog ua ntej.Rau qhov txhais, cov servo lawv ib txwm xav tau ib lub tswv yim ntaus tswv yim.Nws tam sim no, lub tswv yim ntaus ntawv feem ntau yog qhov daws teeb meem los yog cov resolver.Yog hais tias qhov yuav tsum tau ua kom raug, qhov kev ntaus tawm yuav tsum muaj qhov kev daws teeb meem rau kev rov hais dua thiab qhov tseeb .Cov nti tseem yuav tsum tau sib txuas nrog hom teeb liab los ntawm lub tswv yim taw qhia ntawm lub tshuab.
6.Positioning tseeb
Piv txwv, tus decoder kis tau txoj hauj lwm thiab kev ceev ceev ntawm ob txoj hauv kev ntawm lub tsheb nqaj hlau nqus thiab muab xa rov qab rau
amplifier.However, txij thaum cov neeg ntawm cov decoders tau zoo heev tuaj, ib co manufacturers tau pib siv serial
decoders nrog ntau dua cov ntaub ntawv hloov mus rau cov ntaub ntawv ntawm cov ntaub ntawv no.These serial chaw nres nkoj decoders xa cov teeb meem ntau dua rau cov suab nrov nrov dua thiab lwm hom kev tawm tswv yim.These ntxiv cov ntaub ntawv, muaj xws li lub cev kub thiab txawm tus tsav tsheb.
Nyob rau hauv servo systems, thaum lub cav thiab cov thaub tawm tau muab los ntawm tib lub chaw tsim khoom, lub peev xwm ntawm lub tswv yim taw qhia kom paub thiab xa lub cav mus rau lub tshuab thev xaib uas nws tau muab tso tawm tsis muaj kev pom zoo thiab kev tiv thaiv kev tsav tsheb.
7. Kev sib txuas kev sib txuas ua ke
Thaum lub cev muaj zog thiab kev sib tw nrog cov tsav tsheb thiab cov khoom tawm tswv yim sib dhos thiab sib haum xeeb rau
daim ntawv thov, yuav pib xav txog qhov teeb meem hais kom ua ntawm lub amplifier thiab cov tswj kev ua si.Rau ib daim ntawv siv ib sab, nws nquag siv los yog xa cov maub los mus rau ib sab ntawm cov amplifier.Tej kev siv integrate nws mus rau hauv qib siab dua tswj (PLC) lossis cov tshuab hlwb hlau (programmable automation controller (PAC) tswj tau tag nrho tsev los yog kab thiab xa cov ntaub ntawv no mus rau ib qho kev tawm suab ntawm ib qho tawm ntawm cov tswv yim / I / O (I / O) los yog kev sib txuas lus xws li EtherNet / IP lossis Modbus TCP / IP.
8.Control interface xaiv
Hauv kev siv ntau lub cev, cov controllers feem ntau ywj siab.Tam sim no , tus maub los muab qhov kev hais qhia yog feem ntau +10 V teeb liab, sawv cev rau kev ceev los yog torque.Most manufacturers tam sim no muaj kev web-based solutions.These network based solutions yuav tsum thaiv dua thiab tau tuav cov ntsiab lus siab dua thiab tuaj yeem sau cov ntaub ntawv tshawb xyuas ntau ntxiv los ntawm tus neeg hais tau. Muaj ntau lub suab tes hauj lwm muaj, txhua tus uas muaj nws qhov zoo thiab qhov tsis zoo.
9. Qhov kev xaiv ntawm kev tswj xyuas lub zog
Muaj ntau cov kev tswj xyuas suab paj nruag tshiab yog raws li Ethernet kho vajtse thiab siv tag nrho cov nqi ntawm cov nqi uas tau puas tsuaj thiab nce nqi ntxiv.Txawm li ntawd los, koj tsis tuaj yeem xav tias nws yuav tsum tau tshaj cov maub los sis lwm qhov ntawm lub network vim yog RJ-45 connector ntawm lub tshuab thev naus laus zis.
Cov txheej txheem uas khiav ntawm cov kev sib txuas lus no yuav txiav txim siab txog qhov kev sib tw ntawm lub system.EtherCAT, Mechatrolink III thiab Powerlink yog ob peb lub lag luam uas muaj kev sib txuas lus raws li Ethernet thiab muaj kev tswj xyuas cov lus tsa suab .
Network servo systems yog feem ntau configured nrog Ethernet ports uas yuav siv tau ntau txoj kev lag luam xws li Modbus TCP / IP thiab EtherNet / IP los mus tshaj tawm kev tshawb nrhiav thiab khoom siv rau kev saib xyuas network.
