Cov lus piav qhia ua haujlwm
Fais fab mov:DC +;DC-
Voltage: 24 ~ 50DC, feem ntau Linear Power Supply thov (appendix), ripple voltage siab tshaj 50V yuav ua rau tus neeg tsav tsheb puas.Cov zis tam sim no ntawm LPS yuav tsum yog 60% ntau dua li tus neeg tsav tsheb.Nyob rau hauv cov ntaub ntawv ntawm switching fais fab mov (lus pom zoo) thov, thov xyuam xim rau lub tam sim no yuav tsum tau raws li lub cev muaj zog tam sim no.
Nco ntsoov: kev sib txuas tsis raug yuav ua rau tus neeg tsav tsheb puas.
Kev tswj ceev ceev (RV; AVI)
1. Teeb nrawm los ntawm potentiometer (RV).Lub dipswitch SW2 yuav tsum yog ON raws li txoj cai kom pab tau qhov no.CW tig lub potentiometer yuav nce ceev.CCW- speed down.
2. Teeb ceev los ntawm analog input (AVI).Lub dipswitch SW2 yuav tsum OFF raws li txoj cai kom muaj nuj nqi no..AVI davhlau ya nyob twg txais 0 ~ 5V voltage los yog PWM teeb liab los ntawm maub los.AVI davhlau ya nyob twg nrog input tsis kam ntawm 100K, tam sim no noj≤5mA.
Cov ntaub ntawv siv
| SW 2 | Hais kom | Kho ceev | Coman | Tam sim no |
| ON | RV | CW-ua kom nrawm, CCW- nrawm nrawm | - | - |
| OFF | AVI | 0 ~ 5V analog tawm tswv yim | 0-5V zog | ≤ 5mA |
| OFF | AVI | PWM | 1KHz lub luag haujlwm voj voog | - |
Tsuas yog ib qho ntawm ob hom saum toj no tuaj yeem siv los kho qhov nrawm (lwm hom yuav tsum tau qhib).Thaum AVI davhlau ya nyob twg siv, (RV) potentiometer yuav tsum CCW tig mus rau Min.txoj hauj lwm.PWM teeb liab yog 5V TTL theem.
Khiav / Nres(ENBL)
ENBL davhlau ya nyob twg yog siv los tswj lub cev muaj zog Khiav / Nres, Feem ntau zoo davhlau ya nyob twg yog ＋5V.
Optical coupler luv Circuit Court ua lub cev muaj zog khiav, nws qhib Circuit Court ua lub cev muaj zog nres.
Saib hauv qab no Circuit Court
CW / CCW kev sib hloov(F/R)
F / R davhlau ya nyob twg yog siv rau kev hloov lub cev muaj zog rotate kev taw qhia, feem ntau zoo davhlau ya nyob twg yog + 5V.
Lub cev muaj zog khiav hauv CCW thaum optical coupler yog luv luv, lub cev muaj zog khiav hauv CW thaum optical coupler qhib Circuit Court.
Nco ntsoov:tsis txhob hloov cov kev sib txuas ua ntu zus ntawm cov kab hluav taws xob ntawm lub cev muaj zog kom hloov cov kev taw qhia.
lLub cev muaj zog nres Command(BRK)
BRK davhlau ya nyob twg thov kom nres kev sib hloov sai.Lub cev muaj zog yuav nres ib txwm tsis pub dhau 50ms.Tab sis inertia ntawm load tsis tuaj yeem tshaj 2 zaug ntawm lub cev muaj zog inertia, txwv tsis pub nres yuav ua rau lub tswb nrov.
Lub sij hawm ntawm acceleration thiab deceleration yuav tsum tau muab tso rau hauv xws li nyob rau hauv cov ntaub ntawv ntawm loj heev load inertia,
Thiab thov tsis txhob siv nres ua haujlwm hauv qhov xwm txheej zoo li no.
Optical coupler luv Circuit Court yuav nres lub cev muaj zog, optical coupler qhib Circuit Court tso lub cev muaj zog khiav.
Teeb lub kaum sab xis hluav taws xob sib txawv
Dipswitch SW1 tuaj yeem teeb tsa kom haum cov motors nrog cov hluav taws xob sib txawv
| SW 1 | |
| ON | 120 ° los yog 240 ° Hall teeb liab, lawv nyob rau hauv kev sib hloov kev taw qhia |
| OFF | 60 ° lossis 300 ° Hall teeb liab, lawv nyob rau hauv kev sib hloov kev taw qhia |
Motor rotation ceev tso zis(HLUB)
Pulse generated los ntawm tus tsav tsheb yog proportioned nrog lub cev muaj zog ceev, (tso tawm OC tso zis) nws yuav tsum tau nce mus rau ib tug random theem.6 ntau zaus ua tiav cov zis.
Lub cev muaj zog 60 × SPEED (mem tes freq.) / pulses per rev.ntawm lub cev muaj zog; ppr ； lub cev muaj zog ncej khub × 6
Tswb tso zis (ALM)
Tus neeg tsav tsheb yuav nkag mus rau hom kev tiv thaiv thiab nres lub cev muaj zog thaum lub sijhawm dhau tam sim no, OVER VOLTAGE, SHORT CIUCUIT, MOTOR STALL tshwm sim, LED ntawm tus tsav tsheb yuav teeb, thiab ALM teeb liab yuav muaj.Thov txiav tawm
tus tsav tsheb fais fab mov, xyuas cov xaim thiab voltage.High voltage tsis tso cai rau lub cev muaj zog inertia loj, vim nws yuav ua rau khiav / nres ntau zaus thiab tshaj lub tswb nrov.Circuit Court ntawm txoj haujlwm no xa mus rau pic.2.
