Kauj ruam servo / Kaw-loop stepper tsav VS AC servo tsav
AC Servo motors yog respected thiab relied los ntawm tam sim no engineers obsessed nrog kaw-voj kev tswj ntawm servomotors thiab yog qaug nrog cov zoo ntawm siab teb, kev kub ceev, thiab siab raug. Txawm li cas los, AC servo motors kuj muaj cov teeb meem nram qab no uas tsis muaj kev tiv thaiv:
1. Yuav tsis sawv ntsug tseem: Vim yog siv qhov kev tswj kaw-kev tswjhwm, kev ua haujlwm ntawm AC servo lub cev thiab cov yam ntxwv ntawm lub tshuab txiav txim tias lub cav qev tsis tuaj yeem ua kiag li thaum nws raug nres. AC servo lub cav yog ib txwm nyob hauv qhov zoo thiab tsis zoo thaum lub teeb meem me me yog qhov tsawg lossis qhov kev ntsuas ntawm lub cav servo zoo debugged. Fluctuation ntawm 1 mem tes (tuaj yeem tau cai ntawm lub chaw pabcuam tsav tsheb ntawm tus nqi ntawm qhov chaw nyob ntawm tus neeg sab nraud, nws tau hloov ntawm qhov zoo thiab qhov tsis zoo 1). Qhov no yog qhov zoo tshaj plaws uas cuam tshuam rau cov ntaub ntawv hauv kev ua daim duab.
2. Overshoot: Thaum tsiv los ntawm kev kub ceev mus rau qis qis los yog nyob ruaj ruaj, nws yuav tsis tshua saib xyuas qee yam qis thiab ces kho nws rov qab. Thaum tus maub los xa ib qho mem tes rau AC servo lub cev, feem ntau tsis siv ib lub plhaub, tab sis siv 3 pulses thiab ces rov qab tawm 2 pulses. Qhov no yog qhov ua rau neeg raug mob hnyav rau qhov chaw uas muaj cov plhaub mauj yuav tsum tau ua kom muaj suab nrov.
3. Yooj yim debugging: Muaj pua pua ntawm cov kev pab nyob rau hauv qhov kev pab cuam thiab ntau pua nplooj ntawv cov lus qhia rau kev siv; qhov no kuj coj ntau txoj haujlwm rau kev pab cuam tom qab muag thiab kev saib xyuas.
Stepping servo / Closed-loop stepper motors daws cov teeb meem no zoo kawg nkaus.
Txij li cov kauj ruam ntawm cov kauj ruam / cov kauj ruam ntawm stepping lub cav tsis yog ib qho yooj yim ntawm lub cav nrog lub cim ntim nrog lub encoder, nws tsim thiab tsim raws li txoj cai ua haujlwm ntawm AC servo motor system. Nws siv ib tug 32-ntsis DSP ua lub ntsiab processor kom paub meej cov lus teb siab thiab kev kub ceev ntawm tag nrho lub cev. Nws tuaj yeem kho kho lub tshuab tam sim no txhua 25 microseconds.
Ua ntej, cov kev pabcuam Stepping / stepper lub kauj ruam yog ib lub cav ua kauj ruam nrog lub encoder, uas txhais tau hais tias lub ntsiab feature yog tib yam li cov kauj ruam tsav. Thaum lub cev muaj zog lawm, lub tshuab lub cev nres yog kiag li.
Thib ob. Stepping servo / Kaw-ntxees-loop stepper motors tsis overshoot vim lawv ua ke cov nta ntawm cov cav ntoo thiab AC servo tswj (vim hais tias stepper motors tsis overshoot)
Thib peb. Nws yooj yim heev rau kev debug thiab siv. Tsuas yog nws yuav tsum kho qhov chaw ntawm peb lub zog ntawm tus tsav tsheb. Nws yuav siv tsis tau los ntawm cov cuab yeej tsim khoom, tab sis kuj yog cov khoom lag luam. Tus neeg siv yuav tsum muaj tsawg kawg nkaus.
Plaub, tus tsav siv qhov tseeb sine yoj, vector thiab lim txoj kev los tswj cov khoom tam sim no, qhov qis qis yuav raug tswj tau ntawm 0.2 rpm, thiab lub cev muaj zog khiav khov kho thiab muaj zog.
