Yuav ua li cas ib tug multimeter kuaj seb tus encoder yog zoo los yog phem?
(1) Ua ntej siv lub tshuab multimeter, "kev hloov kho tshuab xoom" yuav tsum tau ua ua ntej, uas yog, thaum tsis muaj hluav taws xob ntsuas, lub pointer ntawm multimeter cov ntsiab lus rau txoj hauj lwm ntawm xoom voltage lossis xoom tam sim no.
(2) Thaum siv lub multimeter, tsis txhob kov cov hlau ntawm cov hlau lead ntawm koj txhais tes. Qhov no tuaj yeem ua kom ntsuas qhov tseeb ntawm ib sab tes, thiab kev nyab xeeb ntawm tus kheej ntawm qhov tod tes.
(3) Thaum ntsuas qee qhov hluav taws xob, koj tsis tuaj yeem hloov lub zog thaum ntsuas, tshwj xeeb tshaj yog thaum ntsuas qhov hluav taws xob siab lossis qhov hluav taws xob loj, koj yuav tsum tau saib xyuas ntau dua. Txwv tsis pub, lub multimeter yuav puas. Yog tias koj xav tau hloov lub zog, koj yuav tsum txiav tawm qhov kev sim ua ntej, thiab tom qab ntawd ntsuas tom qab hloov lub zog.
(4) Thaum siv lub multimeter, nws yuav tsum tau muab tso rau kab rov tav kom tsis txhob ua yuam kev. Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj kom tsis txhob muaj kev cuam tshuam ntawm sab nraud magnetic teb ntawm multimeter.
(5) Tom qab siv lub multimeter, qhov hloov pauv yuav tsum tau muab tso rau hauv qhov siab tshaj plaws AC voltage ntau. Yog tias nws tsis siv sijhawm ntev, lub roj teeb hauv lub tshuab hluav taws xob yuav tsum tau muab tshem tawm los tiv thaiv lub roj teeb los ntawm corroding lwm yam khoom hauv lub ntsuas.
Yuav ua li cas siv ib tug multimeter los xyuas seb lub encoder yog zoo los yog phem
Muaj 24V HTL incremental teb encoder. Txuas nws rau ntawm 24V, 0V, A, A-, B, B- mus rau X23 chaw nres nkoj ntawm CU310. Nws tsis tuaj yeem ua haujlwm li qub tom qab lub tshuab hluav taws xob. Lub multimeter ntsuas qhov voltage ntawm lub hwj chim davhlau ya nyob twg yuav tsum yog 2. Xav tias lub encoder yog faulty, kuv txuas lub encoder 4 rau 24V xwb. Qhov ntsuas voltage rau 0 yog A=0V, A-=24V, B=24V, B-=0V. Puas yog tus encoder zoo li qub? Cov chaw tsim khoom encoder tau hais tias tus nqi ib txwm yuav tsum nyob ib puag ncig 15V? Qhov no muaj tseeb rau ntau tus tib encoders.
Lub multimeter tsis tuaj yeem kuaj xyuas seb tus encoder puas zoo li qub. Ib tug multimeter tuaj yeem tshawb xyuas seb qhov incremental encoder zoo lossis phem:
Fais fab ntawm incremental encoder thiab ntsuas qhov tso zis voltage ntawm A / B / Z. Yog tias tsis muaj qhov hluav taws xob tso tawm, qhov hluav taws xob muab hluav taws xob puas lossis lub ntsiab nti puas. Yog tias muaj qee lub sijhawm, maj mam tig lub encoder ncej. Theem A / B yuav tsum yog qhov hloov hluav taws xob. Los ntawm qib siab mus rau qis voltage, qhov tshwm sim yog 1/2, thiab Z yog qib siab ib zaug hauv ib lub voj voog. Cov theem siab voltage feem ntau yog 2V qis dua qhov input voltage lossis siab dua. Yog hais tias ib qho theem tsis tshwm sim siab, Los yog cov zis theem qis heev, ces cov theem puas.
Yog tias txoj kev tshawb pom no zoo, tom qab ntawd saib oscilloscope kom pom seb lub waveform puas tau hloov pauv thiab seb puas muaj cov pulses ploj lawm, thiab tom qab ntawd rov kuaj dua.
