1. Lub hauv paus ntsiab lus ua haujlwm ntawm servo tsav tsheb:
Tam sim no, cov neeg tsav tsheb servo tseem siv tag nrho cov teeb liab digital processor (DSP) ua tus tswj hwm, uas tuaj yeem paub txog kev tswj cov txheej txheem nyuaj, thiab paub txog digitalization, networking thiab kev txawj ntse.Cov cuab yeej siv hluav taws xob feem ntau siv cov khoom siv hluav taws xob ntse (IPM) raws li cov qauv tsim ntawm lub voj voog tsav, IPM sab hauv kev sib koom ua ke tsav Circuit Court, thiab muaj overvoltage, overcurrent, overheating, undervoltage thiab lwm yam txhaum kev tiv thaiv Circuit Court, nyob rau hauv lub ntsiab Circuit Court kuj ntxiv soft start circuit. , txhawm rau txo qhov cuam tshuam ntawm kev pib ntawm tus neeg tsav tsheb.Lub zog tsav tsheb ua ntej kho cov tswv yim peb-theem lossis lub zog hluav taws xob los ntawm peb-theem puv-bridge rectifier circuit kom tau txais cov khoom ncaj qha tam sim no.Peb-theem mus tas li hlau nplaum synchronous AC servo lub cev muaj zog yog tsav los ntawm peb-theem sinusoidal PWM voltage inverter.Tag nrho cov txheej txheem ntawm lub zog tsav tsheb tuaj yeem piav qhia yooj yim raws li AC-DC-AC txheej txheem.Lub ntsiab topological Circuit Court ntawm AC-DC yog peb - theem tag nrho - choj uncontrolled rectifier circuit.
Nrog rau qhov loj-scale daim ntawv thov ntawm servo system, kev siv servo tsav, servo tsav debugging, servo tsav txij nkawm yog cov ntsiab lus tseem ceeb tshaj plaws nyob rau hauv niaj hnub servo tsav, ntau thiab ntau muaj kev tswj technology kev pab cuam nyob rau hauv lub servo tsav technology nyob rau hauv-tob tshawb fawb. .
Servo tsav tsheb yog ib qho tseem ceeb ntawm kev tswj cov lus tsa suab niaj hnub, uas yog siv dav hauv kev lag luam robots thiab CNC machining chaw thiab lwm yam khoom siv automation.Tshwj xeeb tshaj yog, tus neeg tsav tsheb servo siv los tswj AC mus tas li hlau nplaum synchronous lub cev muaj zog tau dhau los ua kev tshawb fawb hotspot hauv tsev thiab txawv teb chaws.Tam sim no, ceev, txoj hauj lwm 3 kaw-voj tswj algorithm raws li vector tswj yog dav siv nyob rau hauv AC servo tsav tsheb tsim.Txawm hais tias qhov ceev kaw-loop tsim nyob rau hauv no algorithm yog tsim nyog los yog tsis plays lub luag hauj lwm tseem ceeb nyob rau hauv tag nrho cov servo tswj system, tshwj xeeb tshaj yog nyob rau hauv kev ua tau zoo ntawm kev ceev tswj.
2. Servo tsav tsheb:
Raws li ib feem tseem ceeb ntawm kev tswj cov lus tsa suab niaj hnub no, nws tau siv dav hauv kev lag luam robots thiab CNC machining chaw thiab lwm yam khoom siv automation.Tshwj xeeb tshaj yog, tus neeg tsav tsheb servo siv los tswj AC mus tas li hlau nplaum synchronous lub cev muaj zog tau dhau los ua kev tshawb fawb hotspot hauv tsev thiab txawv teb chaws.Tam sim no, ceev, txoj hauj lwm 3 kaw-voj tswj algorithm raws li vector tswj yog dav siv nyob rau hauv AC servo tsav tsheb tsim.Txawm hais tias qhov ceev kaw-loop tsim nyob rau hauv no algorithm yog tsim nyog los yog tsis plays lub luag hauj lwm tseem ceeb nyob rau hauv tag nrho cov servo tswj system, tshwj xeeb tshaj yog nyob rau hauv kev ua tau zoo ntawm kev ceev tswj.
Nyob rau hauv qhov ceev kaw-voj ntawm servo tsav tsheb, lub sij hawm real-time ceev ntsuas qhov tseeb ntawm lub cev muaj zog rotor yog ib qho tseem ceeb heev los txhim kho lub dynamic thiab zoo li qub yam ntxwv ntawm kev ceev tswj ntawm lub voj voog ceev.Yuav kom nrhiav tau qhov sib npaug ntawm kev ntsuas qhov tseeb thiab cov nqi ntawm cov khoom siv, cov khoom siv photoelectric incremental feem ntau yog siv los ua qhov ntsuas ntsuas ceev, thiab cov qauv ntsuas ntsuas qhov sib xws yog M / T.Txawm hais tias M / T tachometer muaj qee qhov kev ntsuas qhov tseeb thiab qhov ntsuas dav dav, nws muaj qhov tsis xws luag, suav nrog: 1) tsawg kawg ib tus lej ua tiav disk pulse yuav tsum tau kuaj pom nyob rau lub sijhawm ntsuas, uas txwv qhov ntsuas qhov ntsuas tsawg kawg nkaus;2) Nws yog ib qho nyuaj rau lub timer keyboards ntawm ob lub tshuab tswj tau siv rau kev ntsuas ceev kom tswj tau nruj synchronization, thiab qhov tseeb ntawm kev ntsuas ceev tsis tuaj yeem lav rau hauv lub sijhawm ntsuas nrog kev hloov ceev loj.Yog li ntawd, nws yog ib qho nyuaj los txhim kho qhov kev ua tau zoo ntawm servo tsav tsheb ceev tom qab thiab tswj los ntawm kev siv cov tsoos ceev voj tsim txoj kev.
Cov ntaub ntawv ntxiv:
I. Daim ntawv thov teb:
Servo tsav yog dav siv nyob rau hauv kev txhaj tshuaj molding tshuab, textile machinery, ntim machinery, CNC tshuab cuab yeej thiab hais txog.
Ii.Qhov txawv qhov txawv:
1. Lub servo maub los tau yooj yim hloov lub lag luam module thiab fieldbus module los ntawm qhov tsis siv neeg interface.Nyob rau tib lub sijhawm, qhov sib txawv fieldbus modules tau siv los ua kom tiav cov kev tswj hwm sib txawv (RS232, RS485, optical fiber, InterBus, ProfiBus), thiab kev tswj hom ntawm kev hloov pauv dav dav yog ib leeg.
2. Lub servo maub los yog txuas ncaj qha mus rau lub tshuab hluav taws xob teb lossis lub tshuab encoder los tsim ib lub voj kaw ntawm kev ceev thiab kev hloov pauv.Tab sis lub universal zaus converter tsuas yog tsim ib lub voj qhib lub kaw lus.
3. Txhua qhov kev ntsuas ntsuas (xws li qhov tseeb ntawm lub xeev ruaj khov thiab kev ua haujlwm tsis zoo, thiab lwm yam) ntawm servo maub los zoo dua li ntawm cov zaus hloov pauv.
