A: Yog lawm, tag nrho cov inverter compressor tsav boards suav nrog ua - hauv compressor demagnetization tiv thaiv kom tsis txhob muaj cov hlau nplaum ruaj khov vim yog overcurrent lossis kub siab.
8. Hom motors twg tuaj yeem tsav tau?
A: Cov tsav tsheb yog tsim los rau cov hlau nplaum ruaj khov synchronous motors (PMSM) thiab brushless DC motors (BLDC), haum rau compressors, kiv cua, twj, thiab cov khoom zoo sib xws.
9. Kuv tuaj yeem qhia tau li cas yog tias tus tsav tsheb khiav haujlwm ib txwm?
A: Thaum lub sijhawm ua haujlwm ib txwm muaj, lub teeb ntsuab LED nyob twj ywm thiab lub teeb liab LED flashes maj mam (lossis nrog lub suab nrov). Xa mus rau ntu "Kev Tiv Thaiv Kev Ua Haujlwm" lossis "Fault Code" nyob rau hauv txhua daim ntawv qhia kom ntxaws txog LED xwm txheej.
10. Puas yog cov kiv cua tso zis txhawb kev tswj ceev?
A: Yog. Nws muab 0-10V lossis PWM ceev tswj interface.
11. Qhov siab tshaj plaws tso zis ntawm tus tsav tsheb yog dab tsi?
A: Feem ntau cov khoom txhawb nqa 20-120 rps (piv txwv li, 1200-7200 rpm), nyob ntawm tus qauv lub cev muaj zog thiab compressor.
12. Qhov kev pab cuam yuav hloov kho li cas?
A: Qee cov khoom txhawb kev hloov kho tej thaj chaw deb ntawm 4G IoT module, lossis hauv zos programming ntawm onboard DEBUG chaw nres nkoj siv lub cuab yeej tshwj xeeb.
13. Tus tsav tsheb puas txhawb nqa lub zog-tso tseg?
A: Yog, nws txhawb zog -tawm lub cim xeeb thiab pib- rov pib dua, rov qab ua haujlwm dhau los tom qab lub zog rov qab los.
14. Qhov kev tiv thaiv ingress (IP) ntawm cov khoom yog dab tsi?
A: Feem ntau cov neeg tsav tsheb / cov tswj hwm muaj qhov ntsuas IP00, uas yog qhib - pawg thawj coj saib tsis muaj dej lossis plua plav tiv thaiv. Lawv yuav tsum tau muab tso rau hauv ib lub thawv.
15. Hom valve twg yog qhov hluav taws xob nthuav dav valve (EEV) cuam tshuam?
A: Nws txhawb DC12V ib zaug -ncej stepper motors nrog 1-2 theem excitation. Lub interface yog XH-5 dawb txuas (pinout: ABCD 12V).
16. Dab tsi yog cov av noo yuav tsum tau rau tus tsav tsheb / tswj?
A: Cov khoom yuav tsum ua haujlwm nyob rau hauv ib puag ncig uas tsis yog - condensing. Kev khiav dej num tsawg dua lossis sib npaug li 90%, cia cov av noo tsawg dua lossis sib npaug li 95% (zoo ib yam rau cov khoom siv feem ntau).
17. Qhov kev ua qias tuaj ntawm tus tsav tsheb / tus tswj hwm yog dab tsi?
A: Tag nrho cov khoom lag luam muaj cov pa phem 2, tsim nyog rau kev lag luam ib puag ncig uas tsis yog - cov pa phem tuaj yeem ua rau qee lub sijhawm ua rau muaj kuab paug.
18. Puas muaj cov chaw nres nkoj I/O tshwj tseg rau cov neeg siv kev hloov kho?
A: Feem ntau cov tswj tau khaws cov analog inputs, digital inputs, los yog relay outputs rau cov neeg siv customization. Xa mus rau ntu "Chaw Taw Qhia" thiab "I/O Taw Qhia" hauv cov ntaub ntawv.
19. Nws puas txhawb nqa ntau-unit networking?
A: Qee cov khoom lag luam muab 485-LJ kev sib txuas lus sib txuas, txhawb nqa kev ua haujlwm sib luag lossis kev tswj hwm tus qhev ntawm ntau chav.
20. Qhov siab tshaj plaws RS485 kev sib txuas lus yog dab tsi?
A: Thaum siv shielded cable, RS485 kev sib txuas lus deb tuaj yeem ncav cuag 300 meters. HMI cable ntev yuav tsum tsis pub tshaj 10 meters.
