Mbere yo kuvuga iki kibazo, mbere ya byose, dukwiye gusobanura neza intego ya moteri ya servo, ugereranije na moteri isanzwe, moteri ya servo ikoreshwa cyane cyane muburyo buhagaze neza, mubisanzwe rero tuvuga ko servo igenzura, mubyukuri, ari kugenzura imyanya ya moteri ya servo.Mubyukuri, moteri ya servo nayo ikoresha ubundi buryo bubiri bwo gukora, ni ukuvuga kugenzura umuvuduko no kugenzura umuriro, ariko gusaba ni bike.Kugenzura umuvuduko mubisanzwe bigaragazwa numuyoboro uhindura.Kugenzura umuvuduko hamwe na moteri ya servo ikoreshwa muburyo bwihuta bwihuta no kwihuta cyangwa kugenzura neza umuvuduko, kuko ugereranije nu guhinduranya inshuro, moteri ya servo irashobora kugera kuri revolisiyo ibihumbi muri milimetero nkeya.
Kuberako servo ifunze-loop, umuvuduko urahagaze neza.Igenzura rya Torque ahanini ni ukugenzura ibyasohotse kuri moteri ya servo, nanone kubera igisubizo cyihuse cya moteri ya servo.Gushyira mu bikorwa ubwoko bubiri bwo kugenzura, urashobora gufata servo ya disiki nkumuyoboro uhinduranya, muri rusange hamwe no kugereranya.
Porogaramu nyamukuru ya moteri ya servo cyangwa kugenzura imyanya, iyi mpapuro rero yibanze kuri PLC igenzura imyanya ya servo.Kugenzura imyanya bifite ibintu bibiri bifatika bigomba kugenzurwa, ni ukuvuga umuvuduko n'umwanya.By'umwihariko, ni ukugenzura uburyo moteri ya servo yihuta kugera aho iri no guhagarara neza.
Umushoferi wa servo agenzura intera n'umuvuduko wa moteri ya servo numubare numubare wa pulses yakira.Kurugero, twemeje ko moteri ya servo izahindura buri 10,000.Niba PLC yohereje impiswi 10,000 mumunota, noneho moteri ya servo yuzuza uruziga kuri 1r / min, kandi niba yohereje impiswi 10,000 mumasegonda, noneho moteri ya servo yuzuza uruziga kuri 60r / min.
Kubwibyo, PLC inyuze mugucunga pulse kugirango igenzure moteri ya servo, inzira yumubiri yo kohereza pulse, ni ukuvuga, ikoreshwa rya transistor ya PLC ninzira ikoreshwa cyane, mubisanzwe ni PLC yo hasi-ikoresha ubu buryo.Kandi hagati na ruguru PLC ni ukumenyekanisha umubare ninshuro za pulses kumushoferi wa servo, nka Profibus-DP CANopen, MECHATROLINK-II, EtherCAT nibindi.Ubu buryo bubiri nuburyo butandukanye bwo gushyira mubikorwa, ibyingenzi ni bimwe, kuri programming, ni bimwe.Usibye kwakira pulse, kugenzura disiki ya servo irasa neza nkiya inverter.
Kwandika porogaramu, iri tandukaniro nini cyane, Ikiyapani PLC nugukoresha inzira yinyigisho, naho PLC yu Burayi nugukoresha uburyo bwo guhagarika imikorere.Ariko ibyingenzi ni bimwe, nko kugenzura servo kugirango igende neza, ugomba kugenzura umuyoboro wa PLC usohoka, numero ya pulse, inshuro ya pulse, kwihuta no kwihuta, kandi ukeneye kumenya igihe umwanya wumushoferi wa servo urangiye. , niba yujuje imipaka nibindi.Ntakibazo cyaba PLC bwoko ki, ntakindi kirenze kugenzura ingano yumubiri no gusoma ibipimo byimikorere, ariko uburyo butandukanye bwo gushyira mubikorwa PLC ntabwo ari bumwe.
Ibyavuzwe haruguru nincamake ya moteri ya PLC (programable controller) igenzura servo moteri, noneho tuza gusobanukirwa nogushiraho kwa PLC gahunda yo kugenzura ibintu.
Umugenzuzi wa porogaramu ya PLC yakoreshejwe henshi mubice bitandukanye, kubera ko imbere yacyo igizwe numubare munini wibikoresho bya elegitoroniki, byoroshye guhura nibice bimwe na bimwe bikoresha amashanyarazi bivanze, amashanyarazi akomeye yumuriro w'amashanyarazi, ubushyuhe bwibidukikije nubushuhe, amplitude amplitude nibindi bintu bigira ingaruka kumirimo isanzwe ya mugenzuzi wa PLC, ibi akenshi birengagizwa nabantu benshi.Nubwo gahunda yaba nziza, ukurikije ihuza ryububiko ntiritondere, nyuma yo gukemura, kwiruka bizana kunanirwa kwinshi.Ndiruka ngerageza kubikomeza.
Ibikurikira nuburyo bwo kwirinda:
1. Ibidukikije bya PLC
a, ubushyuhe bwibidukikije buri hagati ya dogere 0 na 55.Niba ubushyuhe buri hejuru cyangwa hasi cyane, ibice by'amashanyarazi by'imbere ntibikora neza.Fata ingamba zo gukonjesha cyangwa gushyushya nibiba ngombwa
b, ubuhehere bwibidukikije ni 35% ~ 85%, ubuhehere buri hejuru cyane, amashanyarazi yumuriro wibikoresho bya elegitoronike ariyongera, byoroshye kugabanya voltage yibigize, ibyuka ni binini cyane kandi byangirika.
C.
d, imbere no hanze yisanduku yamashanyarazi igomba kuba kure hashoboka kure yumurima ukomeye wa magnetiki numurima wamashanyarazi (nka transformateur igenzura, umuyoboro munini wa AC uhuza, ubushobozi bwa capacitori nini, nibindi) ibikoresho byamashanyarazi, kandi byoroshye kubyara ibintu byinshi bihuza (nka frequency frequency, umushoferi wa servo, inverter, thyristor, nibindi) ibikoresho byo kugenzura.
e, irinde gupakira ahantu hamwe n ivumbi ryicyuma, ruswa, gaze yaka, ubushuhe, nibindi
f, nibyiza gushyira ibice byamashanyarazi mugice cyo hejuru cyumuriro wamashanyarazi, kure yubushyuhe, hanyuma ugatekereza gukonjesha no hanze yumuyaga mugihe bibaye ngombwa.
2. Amashanyarazi
a, kugirango ubone neza amashanyarazi ya PLC, hari ingingo zo guhuza bitaziguye.Nka Mitsubishi PLC DC24V;AC voltage niyoroshye kwinjiza, intera ni 100V ~ 240V (yemerewe intera 85 ~ 264), inshuro ni 50 / 60Hz, nta mpamvu yo gukurura switch.Nibyiza gukoresha transformateur yo kwigunga kugirango utange ingufu za PLC.
b, kubisohoka bya PLC DC24V isanzwe ikoreshwa mubikorwa byongerewe imbaraga module itanga amashanyarazi, amashanyarazi yo hanze atatu-ibyuma bitanga amashanyarazi cyangwa izindi ntego, nubwo ibisohoka amashanyarazi ya DC24V afite ibintu biremereye hamwe nibikoresho bigufi birinda imiyoboro hamwe nubushobozi buke.Birasabwa ko ibyuma byuma-bitatu byifashishwa byifashishwa byigenga byoguhindura amashanyarazi kugirango birinde imiyoboro migufi, ishobora guteza PLC kwangirika kandi bigatera ibibazo bitari ngombwa.
3. Kwifuza no kuyobora
Mugihe wiring, igomba guhuzagurika hamwe na tablet ikonje ikonje hanyuma igahuzwa ninjiza nibisohoka bya PLC.Igomba kuba ikomeye kandi ifite umutekano.
Iyo ibyinjijwe ari ikimenyetso cya DC, nkibikikije inkomoko yivanga nibindi byinshi, bigomba gutekereza umugozi ukingiwe cyangwa ugoretse byombi, icyerekezo cyo kumurongo ntigomba kubangikanya numurongo wamashanyarazi kandi ntigishobora gushyirwa kumurongo umwe, umurongo, gukumira kwivanga.
4. Impamvu
Kurwanya ubutaka ntibigomba kurenza Ohms 100.Niba hari ikibanza cyubutaka mumasanduku yamashanyarazi, huza neza na neza nubutaka.Ntukabihuze kubutaka nyuma yo kuyihuza nubutaka bwabandi bagenzuzi (nka feri ihindura).
5. Abandi
a, PLC ntishobora kuba ihagaritse, itambitse ukurikije iyinjizwamo, nka PLC iri kwizirika, ukurikije ishyirwaho ryimigozi kugirango ikomere, idafunguye, mugihe habaye kunyeganyega, kwangiza ibice bya elegitoroniki byimbere, niba ikarita ya gari ya moshi, igomba hitamo ikarita yujuje ibyangombwa, banza ukureho gufunga hanyuma winjire muri gari ya moshi, hanyuma usunike gufunga, nyuma yuko umugenzuzi wa PLC adashobora kuzamuka hejuru.
b, niba ibyasohotse bisohoka ubwoko, ibisohoka aho bigeze ubu ni 2A, muburyo rero mumuzigo munini (nka DC clutch, solenoid valve), nubwo ikiri munsi ya 2A, igomba gutekereza gukoresha inzibacyuho.
