Ua ntej qhia qhov teeb meem no, ua ntej ntawm tag nrho cov, peb yuav tsum paub meej txog lub hom phiaj ntawm servo lub cev muaj zog, txheeb ze rau lub cev muaj zog, servo lub cev muaj zog feem ntau yog siv rau qhov tseeb, yog li peb feem ntau hais txog kev tswj servo, qhov tseeb, yog txoj hauj lwm tswj ntawm servo motor.Qhov tseeb, servo lub cev muaj zog kuj siv ob hom kev ua haujlwm, uas yog, kev tswj ceev thiab kev tswj lub zog, tab sis daim ntawv thov tsawg dua.Kev tswj ceev yog feem ntau pom tau los ntawm kev hloov pauv zaus.Kev tswj ceev nrog servo lub cev muaj zog feem ntau yog siv rau kev nrawm nrawm thiab nrawm lossis nrawm nrawm, vim hais tias txheeb ze rau qhov hloov pauv zaus, servo lub cev muaj peev xwm ncav cuag ntau txhiab tus kiv puag ncig hauv ob peb millimeters.
Vim lub servo yog kaw-voj, qhov ceev yog ruaj khov heev.Torque tswj yog tsuas yog los tswj cov zis torque ntawm lub servo lub cev muaj zog, kuj vim hais tias ntawm cov lus teb ceev ceev ntawm servo lub cev muaj zog.Daim ntawv thov ntawm ob hom kev tswj saum toj no, koj tuaj yeem nqa lub servo tsav raws li kev hloov pauv zaus, feem ntau nrog kev tswj hwm analog.
Daim ntawv thov tseem ceeb ntawm servo lub cev muaj zog lossis qhov chaw tswj, yog li daim ntawv no tsom rau PLC txoj hauj lwm tswj ntawm servo lub cev muaj zog.Kev tswj txoj hauj lwm muaj ob lub cev uas yuav tsum tau tswj, uas yog, ceev thiab txoj hauj lwm.Tshwj xeeb, nws yog tswj kom ceev npaum li cas lub servo lub cev muaj zog mus txog qhov twg nws yog thiab kom raug nres.
Tus neeg tsav tsheb servo tswj qhov kev ncua deb thiab ceev ntawm servo lub cev muaj zog los ntawm cov zaus thiab cov pulses nws tau txais.Piv txwv li, peb pom zoo tias servo lub cev muaj zog yuav tig txhua 10,000 pulses.Yog tias PLC xa 10,000 pulses hauv ib feeb, ces servo lub cev muaj zog ua tiav lub voj voog ntawm 1r / min, thiab yog tias nws xa 10,000 pulses hauv ib pliag, ces lub servo lub cev muaj zog ua tiav lub voj voog ntawm 60r / min.
Yog li ntawd, PLC yog los ntawm kev tswj cov mem tes los tswj lub servo lub cev muaj zog, txoj hauv kev ntawm lub cev xa cov mem tes, uas yog, kev siv PLC transistor tso zis yog txoj kev siv ntau tshaj plaws, feem ntau qis-kawg PLC siv txoj kev no.Thiab qhov nruab nrab thiab siab kawg PLC yog sib txuas lus tus naj npawb thiab zaus ntawm pulses rau tus neeg tsav tsheb servo, xws li Profibus-DP CANopen, MECHATROLINK-II, EtherCAT thiab lwm yam.Ob txoj kev no tsuas yog kev siv sib txawv, qhov tseem ceeb yog tib yam, rau kev ua haujlwm, yog tib yam.Tsuas yog kev txais cov mem tes, kev tswj ntawm lub servo tsav yog raws nraim tib yam li cov inverter.
Rau kev sau ntawv, qhov sib txawv no loj heev, Japanese PLC yog siv txoj kev qhia, thiab European PLC yog siv daim ntawv ntawm kev ua haujlwm blocks.Tab sis qhov tseem ceeb yog tib yam, xws li tswj cov servo mus rau qhov chaw tsis meej, koj yuav tsum tswj PLC cov zis channel, mem tes naj npawb, mem tes zaus, acceleration thiab deceleration lub sij hawm, thiab yuav tsum paub thaum lub servo tsav positioning tiav. , seb puas ua tau raws li qhov txwv thiab lwm yam.Tsis muaj teeb meem dab tsi ntawm PLC, nws tsis muaj dab tsi ntau tshaj li kev tswj hwm ntawm cov khoom siv lub cev thiab kev nyeem cov lus tsa suab, tab sis cov txheej txheem kev siv PLC sib txawv tsis zoo ib yam.
Cov saum toj no yog cov ntsiab lus ntawm PLC (programmable controller) tswj servo lub cev muaj zog, tom qab ntawd peb los nkag siab txog kev teeb tsa ntawm PLC programmable controller ceev faj.
PLC program tswj tau siv dav hauv ntau qhov chaw, vim tias nws sab hauv muaj cov khoom siv hluav taws xob ntau, yooj yim rau kev cuam tshuam los ntawm qee qhov chaw nyob ib puag ncig hluav taws xob cuam tshuam, muaj zog sib nqus teb hluav taws xob, ambient kub thiab av noo, vibration amplitude thiab lwm yam. cuam tshuam rau kev ua haujlwm ntawm PLC maub los, qhov no feem ntau tsis quav ntsej los ntawm ntau tus neeg.Txawm hais tias qhov kev pab cuam zoo dua, raws li qhov txuas txuas tsis tau them sai sai rau, tom qab kev debugging, khiav yuav coj ntau yam tsis ua haujlwm.Kuv tab tom khiav ib ncig ntawm sim tswj nws.
Cov hauv qab no yog cov kev ceev faj rau installation:
1. PLC installation ib puag ncig
a, ambient kub li ntawm 0 txog 55 degrees.Yog tias qhov kub thiab txias dhau los yog qis dhau, cov khoom siv hluav taws xob sab hauv yuav tsis ua haujlwm zoo.Siv qhov ntsuas cua txias lossis ua kom sov yog tias tsim nyog
b, ambient humidity yog 35% ~ 85%, cov av noo siab dhau lawm, cov hluav taws xob conductivity ntawm cov khoom siv hluav taws xob tau txhim kho, yooj yim los txo qhov voltage ntawm cov khoom, tam sim no loj heev thiab puas puas.
c, tsis tuaj yeem ntsia tau rau hauv kev vibration zaus ntawm 50Hz, amplitude yog ntau tshaj 0.5mm, vim hais tias lub vibration amplitude yog loj heev, ua rau lub sab hauv Circuit Court board ntawm cov khoom siv hluav taws xob vuam, poob tawm.
d, sab hauv thiab sab nraum lub thawv hluav taws xob yuav tsum nyob deb li deb li deb ntawm qhov muaj zog sib nqus thiab hluav taws xob (xws li kev tswj transformer, muaj peev xwm loj AC contactor, lub peev xwm loj capacitor, thiab lwm yam) cov khoom siv hluav taws xob, thiab yooj yim los tsim kom muaj kev sib haum xeeb. (xws li zaus converter, servo tsav tsheb, inverter, thyristor, thiab lwm yam) tswj cov cuab yeej.
e, tsis txhob thauj khoom nyob rau hauv qhov chaw nrog hlau plua plav, corrosion, combustible gas, noo noo, thiab lwm yam
f, nws yog qhov zoo tshaj plaws los muab cov khoom siv hluav taws xob tso rau sab sauv ntawm lub thawv hluav taws xob, kom deb ntawm qhov chaw sov, thiab xav txog kev kho cua txias thiab sab nraud tawm thaum tsim nyog.
2. Fais fab mov
a, kom nkag mus rau PLC fais fab mov kom raug, muaj cov ntsiab lus ntawm kev sib cuag ncaj qha.Xws li Mitsubishi PLC DC24V;AC voltage yog hloov tau yooj yim dua, qhov ntau yog 100V ~ 240V (tso cai ntau yam 85 ~ 264), zaus yog 50/60Hz, tsis tas yuav rub lub hloov.Nws yog qhov zoo tshaj plaws los siv kev sib cais transformer los muab PLC lub zog.
b, rau PLC tso zis DC24V feem ntau yog siv rau ncua kev ua haujlwm module fais fab mov, sab nraud peb-xaim sensor fais fab mov lossis lwm lub hom phiaj, txawm hais tias cov zis DC24V fais fab mov muaj overload thiab luv-circuit tiv thaiv pab kiag li lawm thiab muaj peev xwm.Nws raug nquahu tias sab nraud peb-xaim sensor siv lub zog hloov pauv ywj pheej los tiv thaiv luv luv Circuit Court, uas yuav ua rau PLC puas thiab ua rau muaj teeb meem tsis tsim nyog.
3. Kev xaim thiab kev taw qhia
Thaum xaim, nws yuav tsum tau crimped nrog txias xovxwm ntsiav tshuaj thiab tom qab ntawd txuas nrog cov tswv yim thiab cov zis ntawm PLC.Nws yuav tsum nruj thiab ruaj ntseg.
Thaum lub tswv yim yog DC lub teeb liab, xws li cov chaw cuam tshuam ib puag ncig thiab ntau dua, yuav tsum xav txog kev tiv thaiv kab hluav taws xob lossis kev sib tw twisted, cov kev taw qhia hauv online yuav tsum tsis txhob sib npaug rau cov kab hluav taws xob thiab tsis tuaj yeem muab tso rau hauv tib txoj kab qhov, kab raj, tiv thaiv kev cuam tshuam.
4. Hauv av
Kev tiv thaiv hauv av yuav tsum tsis txhob siab tshaj 100 Ohms.Yog tias muaj ib qho av bar hauv lub thawv hluav taws xob, txuas ncaj qha rau hauv av bar.Tsis txhob txuas nws mus rau hauv av bar tom qab txuas nws mus rau hauv av bar ntawm lwm yam controllers (xws li zaus converters).
5. Lwm tus
a, PLC tsis tuaj yeem ntsug, kab rov tav raws li kev teeb tsa, xws li PLC yog fastening, raws li kev teeb tsa ntawm cov ntsia hlau kom nruj, tsis xoob, thaum muaj kev vibration, kev puas tsuaj rau cov khoom siv hluav taws xob sab hauv, yog tias daim npav rail, yuav tsum. xaiv daim npav tsim nyog, ua ntej rub lub xauv thiab tom qab ntawd mus rau hauv daim npav rail, thiab tom qab ntawd thawb lub xauv, tom qab PLC maub los tsis tuaj yeem txav mus los.
b, yog hais tias tus relay tso zis hom, nws cov zis taw tes tam sim no muaj peev xwm yog 2A, yog li nyob rau hauv ib tug loj load (xws li DC clutch, solenoid valve), txawm tias tam sim no yog tsawg tshaj li 2A, yuav tsum xav txog siv relay hloov.
