Fault phenomenon:
CNC system siv 0i-MD system. Thaum lub sijhawm tu, iSVSP servo amplifier ntawm tib lub ntsiab lus tau hloov, nruab nrog i servo motors thiab spindle motors. Thaum lub sij hawm debugging, peb servo axes yuav ua hauj lwm ib txwm, tab sis thaum lub spindle rotation command nyuam qhuav muab, lub SP9012 tswb tshwm sim thaum lub spindle tsis tig.
ua rau qhov teeb meem:
Tej yam ua tau rau lub tswb SP9012 tom qab sab laj cov ntaub ntawv suav nrog:
1. Lub cev muaj zog cable tsis ua haujlwm
2. Lub cev muaj zog rwb thaiv tsev tsis ua haujlwm
3. Cov yam ntxwv ntawm lub cev muaj zog tsis raug teeb tsa kom raug.
4. iSVSP tsis ua hauj lwm
Failure analysis:
1. Raws li qhov tshwm sim txhaum, qhov ua tau ntawm iSVSP tsis ua haujlwm yog qhov tsis zoo vim tias iSVSP yog cov khoom tshiab hloov tshiab.
2. Lub cev muaj zog rwb thaiv tsev tsis ua haujlwm yog ua tau. Koj tuaj yeem siv multimeter los xyuas seb puas muaj kev sib cuag tsis ua haujlwm hauv lub cev muaj zog.
3. Yuav tsum tsis muaj teeb meem nrog lub cev tsis muaj zog vim tias qhov hloov tshiab iSVSP muaj cov yam ntxwv zoo ib yam.
4. Lub cev muaj zog cable tsis ua hauj lwm yog ua tau, vim hais tias hloov iSVSP yuav tsum tau disassembly thiab sib dhos ntawm spindle motor xov hlau. Yog tias cov xov hlau txuas tsis raug (xws li luv luv Circuit Court, grounding los yog kev sib txuas tsis raug), nws yuav ua rau overcurrent hauv lub cev muaj zog.
Kev daws teeb meem:
Kev tshuaj xyuas tau qhia tias qhov ua txhaum yog tshwm sim los ntawm qhov rov qab theem ua ntu zus ntawm cov fais fab cables.
