Ngaphambi kokutshela le nkinga, okokuqala, kufanele sicacise injongo ye-servo motor, ngokuphathelene nemoto evamile, i-servo motor isetshenziselwa ukubeka okunembile, ngakho-ke sivame ukusho ukuthi i-servo yokulawula, empeleni, i-servo motor. ukulawula isikhundla se-servo motor.Eqinisweni, i-servo motor isebenzisa nezinye izindlela ezimbili zokusebenza, okungukuthi, ukulawula isivinini nokulawula i-torque, kodwa isicelo sincane.Ukulawula isivinini ngokuvamile kubonakala ngesiguquli sefrikhwensi.Ukulawula isivinini nge-servo motor ngokuvamile kusetshenziselwa ukusheshisa okusheshayo nokunciphisa noma ukulawulwa kwesivinini okunembile, ngoba uma kuqhathaniswa nesiguquli semvamisa, i-servo motor ingafinyelela izinkulungwane zokuguqukela ngaphakathi kwamamilimitha ambalwa.
Ngenxa yokuthi i-servo ivaliwe-loop, isivinini sizinzile kakhulu.Ukulawula i-torque ngokuyinhloko ukulawula i-torque ephumayo ye-servo motor, futhi ngenxa yokuphendula okusheshayo kwe-servo motor.Ukusebenzisa lezi zinhlobo ezimbili ezingenhla zokulawula, ungathatha idrayivu ye-servo njengesiguquli semvamisa, ngokujwayelekile ngokulawula kwe-analog.
Ukusetshenziswa okuyinhloko kwe-servo motor noma ukulawula ukuma, ngakho leli phepha ligxile ekulawuleni isikhundla se-PLC se-servo motor.Ukulawula isikhundla kunamanani amabili angokwenyama adinga ukulawulwa, okungukuthi, isivinini kanye nesimo.Ngokuqondile, ukulawula ukuthi i-servo motor ifika ngokushesha kangakanani lapho ikhona futhi ime ngokunembile.
Umshayeli we-servo ulawula ibanga nesivinini se-servo motor nge-frequency kanye nenani lama-pulses eliwatholayo.Isibonelo, sivumelene ukuthi i-servo motor izoguqula wonke ama-pulse angu-10,000.Uma i-PLC ithumela ama-pulse angu-10,000 ngomzuzu, khona-ke i-servo motor iqedela umbuthano ku-1r/min, futhi uma ithumela ama-pulse angu-10,000 ngomzuzwana, khona-ke i-servo motor iqedela umbuthano ku-60r/min.
Ngakho-ke, i-PLC ngokulawula i-pulse ukulawula i-servo motor, indlela ebonakalayo yokuthumela i-pulse, okungukuthi, ukusetshenziswa kwe-PLC transistor okukhiphayo kuyindlela evame ukusetshenziswa kakhulu, ngokuvamile i-PLC ephansi isebenzisa le ndlela.Futhi i-PLC yokugcina emaphakathi nephezulu iwukuxhumana nenombolo kanye nemvamisa yama-pulse kumshayeli we-servo, njenge-Profibus-DP CANopen, MECHATROLINK-II, EtherCAT njalonjalo.Lezi zindlela ezimbili ziyiziteshi zokuqalisa ezihlukene, ingqikithi iyafana, yokuhlela, iyafana.Ngaphandle kwe-pulse reception, ukulawulwa kwe-servo drive kufana ncamashi nalokho kwe-inverter.
Ekubhalweni kohlelo, lo mehluko mkhulu kakhulu, i-Japan PLC iwukusebenzisa indlela yokufundisa, kanti i-European PLC iwukusebenzisa uhlobo lwamabhulokhi asebenzayo.Kodwa ingqikithi iyafana, njengokulawula i-servo ukuze ihambe ngokuphelele, udinga ukulawula isiteshi sokuphuma kwe-PLC, inombolo ye-pulse, i-pulse frequency, ukusheshisa kanye nesikhathi sokunciphisa, futhi udinga ukwazi ukuthi ukuma komshayeli we-servo kuqedile nini. , noma ukuhlangabezana nomkhawulo nokunye.Akunandaba ukuthi hlobo luni lwe-PLC, alulutho ngaphandle kokulawulwa kwalezi zibalo ezingokomzimba nokufunda kwemingcele enyakazayo, kodwa izindlela ezihlukile zokuqalisa ze-PLC azifani.
Okungenhla isifinyezo se-PLC (isilawuli esihlelekayo) sokulawula i-servo motor, bese siqonda ukufakwa kwezinyathelo zokuphepha ezihlelekayo ze-PLC.
Isilawuli sohlelo lwe-PLC sisetshenziswe kabanzi emikhakheni ehlukahlukene, ngoba yangaphakathi iqukethe inani elikhulu lezingxenye ze-elekthronikhi, kulula ukuthintwa ukuphazamiseka kwezingxenye zikagesi ezizungezile, insimu kagesi enamandla kazibuthe, izinga lokushisa elizungezile kanye nomswakama, i-vibration amplitude nezinye izici. kuthinta umsebenzi ojwayelekile wesilawuli se-PLC, lokhu kuvame ukunganakwa abantu abaningi.Ngisho noma uhlelo lungcono, ngokusho kwesixhumanisi sokufaka akunaki, ngemva kokulungisa iphutha, ukugijima kuzoletha ukwehluleka okuningi.Ngigijima ngizama ukuyinakekela.
Okulandelayo yizinyathelo zokuphepha zokufakwa:
1. Indawo yokufaka ye-PLC
a, izinga lokushisa le-ambient lisukela ku-0 kuye ku-55 degrees.Uma izinga lokushisa liphezulu kakhulu noma liphansi kakhulu, izingxenye zikagesi zangaphakathi ngeke zisebenze kahle.Thatha izinyathelo zokupholisa noma zokufudumala uma kunesidingo
b, umswakama we-ambient ngu-35% ~ 85%, umswakama uphezulu kakhulu, ukuqhutshwa kukagesi kwezingxenye ze-elekthronikhi kuyathuthukiswa, kulula ukunciphisa amandla kagesi wezingxenye, i-current inkulu kakhulu kanye nomonakalo wokuphuka.
c, ayikwazi ukufakwa imvamisa yokudlidliza ka-50Hz, i-amplitude ingaphezu kuka-0.5mm, ngoba i-amplitude yokudlidliza inkulu kakhulu, okuholela ekuweni kwebhodi lesifunda lezingxenye ze-elekthronikhi.
d, ngaphakathi nangaphandle kwebhokisi likagesi kufanele kube kude ngangokunokwenzeka nenkundla kazibuthe enamandla kanye nenkundla kagesi (njenge-control transformer, umthamo omkhulu we-AC contactor, umthamo omkhulu we-capacitor, njll.) izingxenye zikagesi, futhi kulula ukukhiqiza i-harmonic ephezulu. (okufana nesiguquli semvamisa, umshayeli we-servo, i-inverter, i-thyristor, njll.) amadivayisi okulawula.
e, gwema ukulayisha ezindaweni ezinothuli lwensimbi, ukugqwala, igesi evuthayo, umswakama, njll
f, kungcono kakhulu ukubeka izingxenye zikagesi engxenyeni engenhla yebhokisi likagesi, kude nomthombo wokushisa, futhi ucabangele ukupholisa kanye nokwelashwa kokukhipha umoya wangaphandle uma kudingeka.
2. Ukunikezwa kwamandla
a, ukuze ufinyelele ngendlela efanele ukunikezwa kwamandla kagesi we-PLC, kukhona amaphuzu okuxhumana ngokuqondile.NjengeMitsubishi PLC DC24V;I-AC voltage ingukufaka okuvumelana nezimo, ububanzi bungu-100V~240V (ububanzi obuvunyelwe 85~264), imvamisa ngu-50/60Hz, asikho isidingo sokudonsa iswishi.Kungcono ukusebenzisa i-isolation transformer ukunikeza amandla e-PLC.
b, kokuphumayo kwe-PLC I-DC24V ivamise ukusetshenziselwa ukunikezwa kwamandla wemojula yokusebenza enwetshiwe, amandla angaphandle enzwa yezintambo ezintathu noma ezinye izinjongo, nakuba ukunikezwa kwamandla kwe-DC24V okuphumayo kunomthwalo omningi kanye namadivayisi okuvikela isifunda esifushane namandla alinganiselwe.Kutuswa ukuthi inzwa yangaphandle enezintambo ezintathu isebenzise ugesi oshintshwayo ozimele ukuze ivimbele ukujikeleza okufushane, okungase kubangele ukulimala kwe-PLC futhi kuholele enkingeni engadingekile.
3. Izintambo kanye nesiqondiso
Lapho izintambo, kufanele iboshwe ngethebhulethi yokucindezela okubandayo bese ixhunywa kumatheminali okokufaka nokukhiphayo e-PLC.Kufanele iqine futhi ivikeleke.
Uma okokufaka kuyisignali ye-DC, njengemithombo yokuphazamiseka ezungezile nokunye okwengeziwe, kufanele kucabangele ikhebula elivikelekile noma ipheya esontekile, isiqondiso se-inthanethi akufanele sihambisane nolayini wamandla futhi asikwazi ukubekwa endaweni efanayo yesikhala, ishubhu yomugqa, ukuvimbela ukuphazamiseka.
4. Umhlabathi
Ukumelana nesisekelo akufanele kube ngaphezu kwe-100 Ohms.Uma kune-ground bar ebhokisini likagesi, lixhume ngqo ku-ground bar.Ungayixhumi kubha ephansi ngemva kokuyixhuma kubha ephansi yezinye izilawuli (ezifana neziguquli zefrikhwensi).
5. Abanye
a, i-PLC ayikwazi ukuma mpo, evundlile ngokusho kokufaka, njenge-PLC iyaqina, ngokusho kokufakwa kwezikulufu ukuze ziqinise, zingakhululeki, uma kwenzeka ukudlidliza, ukulimala kwezingxenye ze-elekthronikhi zangaphakathi, uma isitimela sekhadi, kufanele khetha isitimela sekhadi eliqeqeshiwe, qala udonse ilokhi bese ungene esitimeleni sekhadi, bese uphusha ilokhi, ngemuva kokuthi isilawuli se-PLC singakwazi ukunyuka phezulu naphansi.
b, uma uhlobo lokuphumayo kwe-relay, iphoyinti layo lokukhipha amandla lamanje lingu-2A, ngakho-ke emthwalweni omkhulu (njenge-DC clutch, i-valve ye-solenoid), noma ngabe yamanje ingaphansi kuka-2A, kufanele icabangele ukusebenzisa i-relay transition.
