Lub caij no, Programmable Logic Controller (PLC), lub zog muaj zog tswj kev lag luam, tab tom siv dav hauv kev tswj cov zaus inverters. Daim ntawv no piav qhia txog cov hauv paus ntsiab lus ntawm PLC-tswj zaus inverters thiab lawv cov ntawv thov hauv kev lag luam automation, aiming muab cov neeg nyeem nrog rau hauv - nkag siab tob thiab cov ntaub ntawv siv.
II. Cov ntsiab cai ntawm PLC-tswj zaus Inverters
Lub hauv paus ntsiab lus ntawm PLC - tswj zaus inverters yog ua raws li kev ua haujlwm ntawm cov teeb meem tau txais los ntawm cov sensors los ntawm PLC, uas tom qab ntawd tswj cov zis zaus ntawm zaus inverter, yog li ua tiav cov kev cai ntawm lub cev muaj zog ceev. Tshwj xeeb, cov txheej txheem kev sib cuam tshuam ntawm PLC thiab zaus inverter tuaj yeem muab faib ua cov kauj ruam hauv qab no:
Kev Tau Txais Teeb Meem: PLC tau txais cov teeb liab los ntawm cov sensors los ntawm nws cov input modules, xws li encoder signals rau ntsuas lub cev muaj zog ceev. Cov teeb liab no qhia txog qhov tiag - lub sijhawm ua haujlwm ntawm lub cev muaj zog thiab qhov tsis zoo ntawm lub cev muaj zog.
Kev teeb tsa: Lub Chaw Ua Haujlwm Hauv Nruab Nrab (CPU) ntawm PLC ua cov txheej txheem tsim thiab suav ntawm cov cim tau txais. Raws li qhov preset tswj logic thiab algorithms, CPU txiav txim seb lub cev muaj zog qhov kev khiav hauj lwm raws li txoj cai thiab xam tus nqi zaus uas yuav tsum tau rau kev cai.
Tswj cov zis: PLC xa cov teeb liab tswj mus rau zaus inverter los ntawm nws cov zis modules. Cov teeb liab tswj hwm no suav nrog cov lus txib zaus, pib / nres cov lus txib, thiab lwm yam, uas coj cov zaus inverter los kho cov zis zaus thiab yog li paub txog kev tswj lub cev muaj zog.
Cov ntsiab lus hauv qab no yuav tsum tau muab sau tseg hauv cov txheej txheem ntawm PLC tswj zaus inverter:
Kev xaiv ntawm Inverter Operation Channel: Raws li daim ntawv thov tiag tiag, kev ua haujlwm sib txawv tuaj yeem xaiv tau, xws li kev ua haujlwm tseem ceeb channel, davhlau ya nyob twg hais kom ua channel, lossis kev sib txuas lus ua haujlwm hais kom ua channel.
Kev xaiv ntawm Zaus Channel: Kev xaiv ntawm cov zaus channel nyob ntawm qhov kev thov tshwj xeeb thiab cov kev cai tswj hwm, suav nrog ntau txoj hauv kev xws li keyboard digital teeb tsa, keyboard analog channel, davhlau ya nyob twg analog channel, ntau-kev teeb tsa zaus, PID tswj kev teeb tsa, thiab kev sib txuas lus zaus.
III. Kev siv ntawm PLC-tswj zaus Inverters
PLC-tswj zaus inverters muaj ntau yam kev siv hauv kev lag luam automation, thiab ob peb yam kev thov raug teev tseg raws li hauv qab no:
Industrial Production Line Control
Hauv cov kab ntau lawm, kev sib xyaw ntawm PLC thiab zaus inverters ua rau muaj kev sib koom ua ke ntawm ntau lub cev muaj zog, ua kom muaj kev ruaj ntseg thiab ua haujlwm zoo ntawm tag nrho cov kab ntau lawm. Los ntawm PLC programming, lub cev muaj zog ceev thiab hom kev ua haujlwm tuaj yeem hloov kho kom haum rau ntau qhov chaw tsim khoom thiab cov txheej txheem yuav tsum tau ua. Piv txwv li, nyob rau hauv textile machinery, PLC tuaj yeem tswj lub cev muaj zog ceev thiab nro raws li hom ntaub thiab cov txheej txheem yuav tsum tau ua, kom ntseeg tau qhov zoo thiab cov khoom siv ntawm textiles.
Qhov cua thiab cua txias Systems
Nyob rau hauv qhov cua thiab cua txias tshuab, kev tswj kom meej ntawm kiv cua ceev yuav tsum ua kom tiav ib puag ncig zoo hauv tsev thiab kev txuag hluav taws xob. Kev sib xyaw ua ke ntawm PLC thiab zaus inverters tso cai rau lub sijhawm tiag tiag - hloov kho raws li qhov ntsuas hauv tsev xws li kub thiab av noo, paub txog kev tswj tsis siv neeg ntawm kiv cua ceev. Txoj kev tswj hwm no tsis tsuas yog txhim kho kev ua haujlwm ntawm cov tshuab cua txias, tab sis kuj txo cov khoom siv hluav taws xob.
Dej Pump Control Systems
Hauv kev kho dej, kev siv dej thiab cov kav dej, kev ua haujlwm ntawm cov twj tso kua dej yuav tsum tau tswj xyuas kom meej raws li qhov xav tau.
