Ama-Yaskawa servo drives (ama-servodrives), aziwa nangokuthi “isilawuli se-servo sase-Yaskawa” kanye “nesilawuli se-servo sase-Yaskawa”, ayisilawuli esisetshenziselwa ukulawula ama-servo motors.Umsebenzi wayo ufana nowokuguqulela imvamisa kumamotho ajwayelekile e-AC, futhi ungowohlelo lwe-servo Ingxenye yokuqala uhlelo lokubeka nokubeka indawo.Ngokuvamile, i-servo motor ilawulwa ngesikhundla, isivinini kanye ne-torque ukuze kuzuzwe ukuma okuyinhloko kokuma kwesistimu yokudlulisa.Njengamanje iwumkhiqizo osezingeni eliphezulu wobuchwepheshe bokudlulisa.Uhlelo lwamarobhothi e-Yaskawa oludidiyelwe lwe-Yaskawa servo drive ukulungisa uhlelo.
Amaphutha ajwayelekile kanye nezixazululo ze-Yaskawa robot servo drives
1. Imojula yesondlo somshayeli we-Yaskawa i-DC overvoltage-fault phenomenon: Ngesikhathi sokuvala nokunciphisa inqubo ye-inverter, amaphutha emojula ye-DC overvoltage enzeka izikhathi eziningi, okubangela ukuthi iswishi yamandla kagesi aphezulu ihambe.I-voltage yebhasi yomsebenzisi iphezulu kakhulu, ibhasi langempela likagesi we-6KV lingaphezulu kuka-6.3KV, futhi ibhasi langempela likagesi we-10KV lingaphezulu kuka-10.3KV.Lapho i-voltage yebhasi isetshenziswa ku-inverter, i-module input voltage iphezulu kakhulu, futhi imojula ibika ukugcwala kwebhasi le-DC.Phakathi nenqubo yokuqalisa i-inverter, ibhasi le-DC le-inverter line-voltage ngaphezulu uma i-Yaskawa servo drive isebenza cishe ku-4HZ.
Isizathu sephutha: Ngesikhathi senqubo yokuvala i-inverter, isikhathi sokunciphisa sishesha kakhulu, okubangela ukuthi injini ibe sesimweni se-generator.Imoto ibuyisela amandla ebhasini le-DC lemojula ukuze ikhiqize i-voltage yokumpompa, okubangela ukuthi i-voltage yebhasi ye-DC ibe phezulu kakhulu.Njengoba i-wiring ejwayelekile yefekthri yama-on-site transformers ingu-10KV no-6KV, uma i-voltage yebhasi idlula i-10.3KV noma i-6.3KV, i-voltage ephumayo ye-transformer izoba phezulu kakhulu, okuzokwandisa i-voltage yebhasi yemoduli futhi kubangele ukugcwala ngokweqile.Umshayeli we-servo we-Yaskawa ulungisa ukuxhunywa okuhlanekezela ama-optical fibers amamojula wesigaba esihlukene endaweni efanayo (isibonelo, ukuxhuma okuhlanekezela ama-optical fibers A4 kanye ne-B4), okubangela ukukhishwa kwe-voltage yesigaba ukuba kudlule amandla.
Isixazululo:
Nweba kahle isikhathi sokukhuphuka/phansi kanye nesikhathi sokwehlisa.
Khulisa iphoyinti lokuvikela ukugcwala kwe-overvoltage kumojula, manje yonke i-1150V.
Uma i-voltage yomsebenzisi ifinyelela ku-10.3KV (6KV) noma ngaphezulu, shintsha isiphetho esifushane sesiguquli sibe ngu-10.5KV (6.3KV).Ukulungiswa kwedrayivu ye-Yaskawa servo hlola ukuthi i-fiber optical ixhunyiwe ngokungalungile futhi ulungise i-optical fiber exhunywe ngokungalungile.
2. Irobhothi yedijithali ye-AC servo system MHMA 2KW.Ngokushesha lapho amandla evuliwe phakathi nokuhlolwa, injini iyandindizela futhi yenza umsindo omkhulu, bese umshayeli ebonisa i-alamu No. 16. Indlela yokuxazulula inkinga?
Lesi senzakalo ngokuvamile sibangelwa ukulungiselelwa kwenzuzo yomshayeli ukuba phezulu kakhulu, okuholela ekuzulisekeni okujabulisayo.Sicela ulungise amapharamitha N.10, N.11, kanye no-N.12 ukuze wehlise ngokufanelekile ukuzuza kwesistimu.
3. I-alamu No. 22 ivela lapho irobhothi AC servo umshayeli ivuliwe.Kungani?
I-alamu No. 22 iyi-alamu yephutha le-encoder.Izimbangela ngokuvamile ziyi:
A. Kunenkinga ngezintambo zesifaki khodi: ukunqanyulwa, ukujikeleza okufushane, ukuxhuma okungalungile, njll. Sicela uhlole ngokucophelela;
B. Kunenkinga ngebhodi lesekethe yesifaki khodi kumotho: ukungaqondi kahle, umonakalo, njll. Sicela ulithumele ukuze lilungiswe.
4. Uma irobhothi i-servo motor igijima ngesivinini esiphansi kakhulu, kwesinye isikhathi iyashesha futhi kwesinye isikhathi yehlise ijubane, njengokukhasa.Kumele ngenzeni?
Ukukhasa okunesivinini esiphansi se-servo motor ngokuvamile kubangelwa ukuzuza kwesistimu ukuba kuphansi kakhulu.Sicela ulungise amapharamitha N.10, N.11, kanye no-N.12 ukuze ulungise ngokufanelekile ukuzuza kwesistimu, noma uqalise umsebenzi wokulungisa ukuzuza okuzenzakalelayo komshayeli.
5. Kumodi yokulawula indawo yesistimu ye-robot AC servo, isistimu yokulawula ikhipha amasignali e-pulse ne-directional, kodwa kungakhathaliseki ukuthi umyalo wokujikeleza phambili noma umyalo wokuzungeza okuphambene, i-motor izungeza kuphela ohlangothini olulodwa.Kungani?
I-robot AC servo system ingathola amasiginali amathathu okulawula kumodi yokulawula isikhundla: i-pulse/direction, phambili/reverse pulse, kanye ne-A/B orthogonal pulse.Ukulungiselelwa kwefekthri komshayeli kuyi-A/B quadrature pulse (No42 ngu-0), sicela ushintshe i-No42 iye ku-3 (isignali ye-pulse/direction).
6. Uma usebenzisa i-robot AC servo system, ingabe i-servo-ON ingasetshenziswa njengesignali yokulawula injini ungaxhunyiwe ku-inthanethi ukuze shaft yemoto ijikelezwe ngokuqondile?
Nakuba injini ikwazi ukuphuma ku-inthanethi (esimeni esikhululekile) lapho isignali ye-SRV-ON inqanyulwa, ungayisebenzisi ukuqalisa noma ukumisa injini.Ukuyisebenzisa njalo ukuvula nokuvala injini kungalimaza idrayivu.Uma udinga ukusebenzisa umsebenzi ongaxhunyiwe ku-inthanethi, ungashintsha imodi yokulawula ukuyifinyelela: ucabanga ukuthi uhlelo lwe-servo ludinga ukulawulwa kwesikhundla, ungasetha ipharamitha yokukhetha imodi yokulawula No02 kuya ku-4, okungukuthi, imodi ukulawula isikhundla, futhi imodi yesibili ukulawula torque.Bese usebenzisa i-C-MODE ukuze ushintshe imodi yokulawula: lapho wenza isilawuli sendawo, vula isignali ye-C-MODE ukuze wenze idrayivu isebenze ngemodi eyodwa (okungukuthi, ukulawula indawo);uma idinga ukuphuma ku-inthanethi, vula isignali ye-C-MODE ukuze wenze umshayeli asebenze ngemodi yesibili (okungukuthi, ukulawula i-torque).Njengoba okokufaka komyalo we-torque i-TRQR ingenantambo, i-torque ephumayo yemoto inguziro, ngaleyo ndlela izuze ukusebenza okungaxhunyiwe ku-inthanethi.
7. Irobhothi i-AC servo esetshenziswe emshinini wokugaya we-CNC esiyithuthukisile isebenza kumodi yokulawula i-analog, futhi isignali yendawo ibuyiselwa kukhompyutha ukuze icutshungulwe ngokuphuma kwe-pulse yomshayeli.Ngesikhathi sokulungisa iphutha ngemuva kokufakwa, lapho kukhishwa umyalo wokunyakaza, injini izondiza.Siyini isizathu?
Lesi simo sibangelwa ukulandelana kwesigaba okungalungile kwesignali ye-quadrature ye-A/B ebuyiselwa emuva isuka kumshini wokushaya womshayeli iye kukhompyutha, okwenza impendulo eyakhayo.Kungenziwa ngezindlela ezilandelayo:
A. Lungisa uhlelo lwesampula noma i-algorithm;
B. Shintshanisa u-A+ no-A- (noma u-B+ no-B-) wesiginali yokuphuma komshayeli ukuze ushintshe ukulandelana kwesigaba;
C. Guqula ipharamitha yomshayeli No45 futhi ushintshe ukulandelana kwesigaba sesignali yayo yokuphuma kwe-pulse.
