1. Overcurrent faults
Overcurrent faults yuav muab faib ua acceleration, deceleration thiab tas li ceev overcurrent. Tej zaum nws yuav tshwm sim los ntawm lub sij hawm acceleration thiab deceleration ntawm lub inverter yog luv luv, cia li hloov nyob rau hauv lub load, uneven load faib, short-circuiting ntawm cov zis, thiab lwm yam. Qhov no feem ntau yuav ua tau los ntawm ncua lub acceleration thiab deceleration lub sij hawm, txo. kev hloov pauv tam sim ntawd ntawm kev thauj khoom, ntxiv zog braking ntsiab, nqa tawm load faib tsim, thiab xyuas cov kab. Yog tias disconnect lub load inverter los yog overcurrent txhaum, nws txhais tau hais tias lub inverter inverter Circuit Court tau lub nplhaib, yuav tsum tau hloov lub inverter.
2. Overload txhaum
Overload faults muaj xws li inverter overload thiab lub cev muaj zog overload. Nws muaj peev xwm hais tias lub sij hawm acceleration yog luv luv, daim phiaj voltage tsawg dhau, lub load hnyav dhau lawm thiab lwm yam yog vim li cas. Feem ntau, koj tuaj yeem txuas ntxiv lub sijhawm nrawm, txuas ntxiv lub sijhawm braking, xyuas cov kab hluav taws xob hluav taws xob, thiab lwm yam. Lub nra hnyav dhau lawm thiab lub cev muaj zog thiab inverter xaiv tsis tuaj yeem rub lub load, uas kuj tuaj yeem tshwm sim los ntawm cov neeg kho tshuab lubrication tsis zoo. Xws li cov qub yuav tsum tau hloov lub siab zog lub cev muaj zog thiab inverter; xws li tom kawg mus rau cov tshuab ntau lawm los kho dua.
3. Nyob rau hauv voltage
Nws txhais tau hais tias muaj teeb meem nrog lub hwj chim input ib feem ntawm lub inverter, uas yuav tsum tau xyuas ua ntej nws yuav khiav.
