Mfundo yogwira ntchito ya servo drive

1. Mfundo yoyendetsera servo driver:

Pakalipano, madalaivala akuluakulu a servo onse amagwiritsa ntchito digito signal processor (DSP) monga maziko olamulira, omwe amatha kuzindikira zovuta zowonongeka, ndikuzindikira digito, maukonde ndi luntha.Zida zamagetsi nthawi zambiri zimagwiritsa ntchito mphamvu zamagetsi zamagetsi (IPM) monga kapangidwe kake ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. , pofuna kuchepetsa zotsatira za njira yoyambira pa dalaivala.Gawo loyendetsa magetsi limakonza kaye zolowetsa zagawo zitatu kapena mphamvu zama mains kudzera pagawo la magawo atatu a full-bridge rectifier kuti apeze mphamvu yachindunji yofananira.Magawo atatu okhazikika maginito synchronous AC servo mota amayendetsedwa ndi magawo atatu a sinusoidal PWM voltage inverter.Njira yonse yoyendetsera magetsi imatha kufotokozedwa ngati njira ya AC-DC-AC.Dera lalikulu la topological la AC-DC ndi gawo la magawo atatu lodzaza - mlatho wosalamulirika wowongolera.

Ndi kugwiritsa ntchito kwakukulu kwa dongosolo la servo, kugwiritsa ntchito servo drive, servo drive debugging, servo drive kukonza ndizofunikira kwambiri mitu yaukadaulo masiku ano servo drive, ochulukirachulukira opereka ukadaulo wowongolera mafakitale paukadaulo wa servo drive mozama kafukufuku. .

Dalaivala wa Servo ndi gawo lofunikira pakuwongolera koyenda kwamakono, komwe kumagwiritsidwa ntchito kwambiri m'maloboti amakampani ndi malo opangira makina a CNC ndi zida zina zamagetsi.Makamaka, dalaivala servo ntchito kulamulira AC okhazikika maginito synchronous galimoto wakhala kafukufuku hotspot kunyumba ndi kunja.Panopa, liwiro, malo 3 otsekedwa-loop control aligorivimu yotengera kuwongolera vekitala amagwiritsidwa ntchito kwambiri pakupanga kwa AC servo driver.Kaya liwiro lotsekeka lotsekeka mu algorithm iyi ndiloyenera kapena ayi limagwira ntchito yofunika kwambiri pamayendedwe onse a servo, makamaka pakuwongolera liwiro.

2. Woyendetsa Servo:

Monga gawo lofunikira pakuwongolera koyenda kwamakono, limagwiritsidwa ntchito kwambiri m'maloboti amakampani ndi malo opangira makina a CNC ndi zida zina zamagetsi.Makamaka, dalaivala servo ntchito kulamulira AC okhazikika maginito synchronous galimoto wakhala kafukufuku hotspot kunyumba ndi kunja.Panopa, liwiro, malo 3 otsekedwa-loop control aligorivimu yotengera kuwongolera vekitala amagwiritsidwa ntchito kwambiri pakupanga kwa AC servo driver.Kaya liwiro lotsekeka lotsekeka mu algorithm iyi ndiloyenera kapena ayi limagwira ntchito yofunika kwambiri pamayendedwe onse a servo, makamaka pakuwongolera liwiro.

Mu liwiro lotsekeka la dalaivala wa servo, kuyeza kwanthawi yeniyeni kwa liwiro la mota rotor ndikofunikira kwambiri kuwongolera mawonekedwe osunthika komanso osasunthika pakuwongolera liwiro la lupu.Kuti tipeze kuchulukana pakati pa kulondola kwa kuyeza ndi mtengo wamakina, makina owonjezera a photoelectric amagwiritsidwa ntchito ngati sensa yoyezera liwiro, ndipo njira yoyezera liwiro ndi M/T.Ngakhale kuti tachometer ya M / T ili ndi kulondola koyezera komanso kusiyanasiyana koyezera, ili ndi zolakwika zake, kuphatikizapo: 1) osachepera code disk pulse iyenera kudziwika panthawi yoyezera, yomwe imachepetsa liwiro loyezeka;2) Ndizovuta kwa masinthidwe a nthawi ya machitidwe awiri owongolera omwe amagwiritsidwa ntchito poyezera liwiro kuti asunge kulumikizana mwamphamvu, ndipo kulondola kwa kuyeza liwiro sikungatsimikizidwe muzochitika zoyezera ndi kusintha kwakukulu kwa liwiro.Chifukwa chake, ndizovuta kukonza magwiridwe antchito a servo driver liwiro kutsatira ndi kuwongolera pogwiritsa ntchito njira yopangira liwiro la loop.

Zambiri:

I. Munda wa ntchito:

Servo drive imagwiritsidwa ntchito kwambiri pamakina opangira jakisoni, makina opangira nsalu, makina onyamula, zida zamakina a CNC ndi zina zotero.

Ii.Kusiyanasiyana Koyenera:

1. Woyang'anira servo amatha kusintha mosavuta gawo la ntchito ndi gawo la fieldbus kudzera muzochita zokha.Panthawi imodzimodziyo, ma modules osiyanasiyana a fieldbus amagwiritsidwa ntchito kuti akwaniritse mitundu yosiyanasiyana yolamulira (RS232, RS485, fiber optical, InterBus, ProfiBus), ndipo njira yoyendetsera ma frequency converter ndi amodzi.

2. Woyang'anira servo amalumikizidwa mwachindunji ndi rotary transformer kapena encoder kuti apange chipika chotsekedwa cha liwiro ndi kuwongolera kusamuka.Koma chosinthira pafupipafupi chapadziko lonse lapansi chimangopanga njira yotseguka yowongolera.

3. Chilolezo chilichonse chowongolera (monga kulondola kwanthawi zonse ndi magwiridwe antchito amphamvu, ndi zina zotero) za servo controller ndi zabwino kuposa zosinthira pafupipafupi.
