Ngaphambi kokuba sixelele le ngxaki, okokuqala, kufuneka sicace malunga nenjongo ye-servo motor, ngokumalunga ne-motor eqhelekileyo, i-servo motor isetyenziselwa indawo echanekileyo, ngoko sihlala sithi i-servo yokulawula, enyanisweni, ulawulo lwendawo ye-servo motor.Enyanisweni, i-servo motor isebenzisa ezinye iindlela ezimbini zokusebenza, oko kukuthi, ukulawula isantya kunye nokulawula i-torque, kodwa isicelo sincinci.Ulawulo lwesantya lubonwa ngokubanzi ngesiguquli samaza.Ulawulo lwesantya nge-servo motor lusetyenziswa ngokubanzi ukukhawulezisa ngokukhawuleza kunye nokunciphisa isantya okanye ulawulo oluchanekileyo lwesantya, kuba ngokunxulumene nesiguquli samaza, i-servo motor inokufikelela kumawaka eenguqu ngaphakathi kweemilimitha ezimbalwa.
Ngenxa yokuba i-servo ivaliwe-loop, isantya sizinzile kakhulu.Ulawulo lwe-torque ikakhulu kukulawula i-torque ephumayo ye-servo motor, nangenxa yokuphendula ngokukhawuleza kwe-servo motor.Ukusetyenziswa kwezi ntlobo zimbini zolawulo zingentla, ungathatha i-servo drive njenge-converter frequency, ngokubanzi ngolawulo lwe-analog.
Esona sicelo siphambili se-servo motor okanye ulawulo lokumisa, ke eli phepha ligxile kwi-PLC yolawulo lwendawo ye-servo motor.Ulawulo lwesikhundla lunezixa ezibini zomzimba ezifuna ukulawulwa, oko kukuthi, isantya kunye nesikhundla.Ngokukodwa, kukulawula ukukhawuleza kwemoto ye-servo apho ikhoyo kunye nokuyeka ngokuchanekileyo.
Umqhubi we-servo ulawula umgama kunye nesantya se-servo motor ngokuphindaphindiweyo kunye nenani lee-pulses elifumanayo.Umzekelo, savumelana ukuba i-servo motor iya kuguqula zonke iipulse ezingama-10,000.Ukuba i-PLC ithumela i-10,000 pulses ngomzuzu, ngoko i-servo motor igqiba isangqa kwi-1r / min, kwaye ukuba ithumela i-pulses ye-10,000 ngomzuzwana, ngoko i-servo motor igqiba isangqa kwi-60r / min.
Ngoko ke, i-PLC ngokulawulwa kwe-pulse ukulawula i-servo motor, indlela ebonakalayo yokuthumela i-pulse, oko kukuthi, ukusetyenziswa kwe-PLC transistor output yeyona ndlela isetyenziswa ngokuqhelekileyo, ngokuqhelekileyo i-PLC ephantsi isebenzisa le ndlela.Kwaye isiphelo esiphakathi kunye nesiphezulu se-PLC kukunxibelelana nenani kunye nokuphindaphinda kwee-pulses kumqhubi we-servo, njenge-Profibus-DP CANopen, MECHATROLINK-II, EtherCAT njalo njalo.Ezi ndlela zimbini ziyimijelo yokuphunyezwa eyahlukileyo, ingundoqo iyafana, kwiprogram, iyafana.Ngaphandle kwe-pulse reception, ulawulo lwe-servo drive lufana ngqo nelo lokuguqula.
Ukubhalwa kwenkqubo, lo mahluko mkhulu kakhulu, i-PLC yaseJapan kukusebenzisa indlela yomyalelo, kunye ne-European PLC kukusebenzisa uhlobo lweebhloko ezisebenzayo.Kodwa i-essence iyafana, njengokulawula i-servo ukuya kwindawo epheleleyo, kufuneka ulawule itshaneli ye-PLC yokuphuma, inombolo ye-pulse, i-pulse frequency, i-acceleration kunye nexesha lokunciphisa, kwaye kufuneka ukwazi ukuba indawo yomqhubi we-servo igqityiwe. , nokuba ukuhlangabezana nomda kunye nokunye.Kungakhathaliseki ukuba luhlobo luni lwe-PLC, alukho ngaphezu kokulawulwa kwezi zixa zomzimba kunye nokufundwa kweeparamitha ezishukumayo, kodwa iindlela ezahlukeneyo zokuphunyezwa kwe-PLC azifani.
Oku kungasentla sisishwankathelo se-PLC (isilawuli esicwangcisiweyo) solawulo lwe-servo motor, emva koko siye siqonde ukufakwa kwe-PLC ecwangcisiweyo yokulawula izilumkiso.
Isilawuli senkqubo ye-PLC sisetyenziswe ngokubanzi kwiinkalo ezahlukeneyo, kuba ngaphakathi kwayo kukho inani elikhulu lamacandelo e-elektroniki, kulula ukuchatshazelwa luphazamiseko oluthile olujikelezileyo lombane, intsimi yombane enamandla, ubushushu obuphakathi kunye nokufuma, i-vibration amplitude kunye nezinye izinto. kuchaphazela umsebenzi oqhelekileyo womlawuli we-PLC, oku kuhlala kungahoywa ngabantu abaninzi.Nokuba inkqubo ingcono, ngokutsho kwekhonkco lokufakela ayikhathaleli, emva kokulungiswa kweempazamo, ukuqhuba kuya kuzisa ukusilela okuninzi.Ndijikeleza ndizama ukuyigcina.
Ezi zilandelayo zizilumkiso zofakelo:
1. Indawo yokufaka i-PLC
a, iqondo lobushushu ambient ukusuka 0 ukuya 55 degrees.Ukuba iqondo lokushisa liphezulu kakhulu okanye liphantsi kakhulu, amacandelo ombane angaphakathi akayi kusebenza kakuhle.Thatha amanyathelo okupholisa okanye okufudumala xa kukho imfuneko
b.
c, ayikwazi ukufakwa kwi-vibration frequency ye-50Hz, i-amplitude ingaphezulu kwe-0.5mm, kuba i-vibration amplitude inkulu kakhulu, ekhokelela kwibhodi yesekethe yangaphakathi ye-electronic components welding, iwa.
d, ngaphakathi nangaphandle kwebhokisi yombane kufuneka ibe kude kangangoko kunokwenzeka kude kwintsimi eyomeleleyo yamagnetic kunye nentsimi yombane (efana ne-transformer yokulawula, umthamo omkhulu we-AC contactor, umthamo omkhulu we-capacitor, njl. njl.) amacandelo ombane, kwaye kulula ukuvelisa i-harmonic ephezulu. (ezifana ne-converter frequency, umqhubi we-servo, inverter, thyristor, njl.) izixhobo zokulawula.
e, kuphephe ukulayisha kwiindawo ezinothuli lwesinyithi, ukubola, igesi evuthayo, ukufuma, njl
f, kungcono ukubeka izinto zombane kwindawo ephezulu yebhokisi yombane, kude nomthombo wobushushu, kwaye uqwalasele ukupholisa kunye nonyango lokukhupha umoya wangaphandle xa kuyimfuneko.
2. Unikezelo lwamandla
a, ukufikelela ngokuchanekileyo unikezelo lombane PLC, kukho iindawo zoqhagamshelwano ngqo.NjengeMitsubishi PLC DC24V;I-AC voltage igalelo eliguquguqukayo ngakumbi, uluhlu luyi-100V ~ 240V (uluhlu oluvunyelweyo 85 ~ 264), i-frequency yi-50 / 60Hz, akukho mfuneko yokutsala iswitshi.Kungcono ukusebenzisa i-transformer yodwa ukunika amandla e-PLC.
b, ngenxa PLC imveliso DC24V isetyenziswa ngokubanzi unikezelo lwamandla imodyuli umsebenzi eyandisiweyo, yangaphandle-wire wire sensor unikezelo lwamandla okanye ezinye iinjongo, nangona imveliso DC24V unikezelo lwamandla lunomthwalo omninzi kunye nezixhobo zokukhusela ezimfutshane kunye nomthamo olinganiselweyo.Kucetyiswa ukuba i-sensor yangaphandle ye-3-wire sensor isebenzise unikezelo lwamandla oluzimeleyo lokutshintsha umbane ukukhusela isiphaluka esifutshane, esinokubangela umonakalo we-PLC kwaye kukhokelela kwinkathazo engeyomfuneko.
3. Iingcingo kunye nolwalathiso
Xa i-wiring, kufuneka ifakwe i-crimp nge-tablet yokucinezela ebandayo kwaye emva koko iqhagamshelwe kwi-terminal yegalelo kunye nemveliso ye-PLC.Kufuneka iqine kwaye ikhuseleke.
Xa igalelo isignali ye-DC, njengemithombo yokuphazamiseka ejikelezileyo kunye nokunye, kufuneka kuthathelwe ingqalelo intambo ekhuselekileyo okanye isibini esijijekileyo, ulwalathiso lwe-intanethi akufanele luhambelane nomgca wamandla kwaye alukwazi ukufakwa kwi-slot yomgca ofanayo, ityhubhu yomgca, ukuthintela ukuphazamiseka.
4. Umhlaba
Ukumelana nomhlaba akufanele kube ngaphezu kwe-100 Ohms.Ukuba kukho ibha yomhlaba kwibhokisi yombane, yidibanise ngokuthe ngqo kwibar yomhlaba.Musa ukuyidibanisa kwibar yomhlaba emva kokuyidibanisa kwibar yomhlaba yabanye abalawuli (njengabaguquleli befrikhwensi).
5. Abanye
a, PLC ayikwazi nkqo, ethe tye ngokofakelo, ezifana PLC ukuqinisa, ngokutsho ufakelo izikrufu ukuqinisa, hayi ikhululekile, kwimeko vibration, umonakalo kumacandelo angaphakathi elektroniki, ukuba ikhadi likaloliwe, kufuneka. khetha isiporo sekhadi eliqeqeshiweyo, qala utsale isitshixo emva koko ungene kuloliwe wekhadi, emva koko utyhale isitshixo, emva kokuba isilawuli sePLC singakwazi ukunyuka nokuhla.
b, ukuba i-relay output type, i-output point yayo yangoku umthamo we-2A, ngoko kumthwalo omkhulu (njenge-DC clutch, i-valve ye-solenoid), nokuba i-current ingaphantsi kwe-2A, kufuneka ithathele ingqalelo ukusebenzisa i-relay transition.
