Ku-CNC plasma cutters, ama-VFD asetshenziselwa  ukulawula ukuphakama kwethoshi, izinga lokuphakelayo, nokunyakaza kokusika . Ukulawulwa kwesivinini okuzinzile kusiza ukugcina ukujula kokusika okungaguquki, imiphetho ehlanzekile, kanye nokusetshenziswa kahle kwamandla ngesikhathi sokusebenza.

 

Kusukela ekwenzeni ukhuni kuye ekwenziweni kwensimbi, ama-CNC VFD adlala indima ebalulekile ekuthuthukiseni  ukunemba, ukusebenza kahle, nokulawula  kuzo zonke izinhlobo zemishini ye-CNC. Noma ngabe ukusika, ukugaywa, noma ukuqoshwa, ukusetshenziswa kwe-VFD kuqinisekisa  ukusebenza kahle kwe-spindle  nokuthembeka  kwesikhathi eside  kumasistimu esimanje e-CNC.

 

 Amathiphu Okulungisa ama-CNC VFDs 

 

Ukunakekelwa okufanele kwe yakho  -CNC Variable Frequency Drive (VFD)  kubalulekile ukuze kuqinisekiswe ukusebenza okuzinzile, ukunciphisa isikhathi sokuphumula, nokwelula impilo yonke yesistimu yakho ye-CNC. Njengoba i-VFD idlala indima ebalulekile ekulawuleni isivinini se-spindle motor kanye ne-torque, ukuyigcina isesimweni esifanele kubalulekile ekusebenzeni komshini okuthembekile.

Landela lezi zinyathelo zokunakekela ezibalulekile:

 

 Hlanza Ama-air Vents kanye nezihlungi 

Khipha njalo uthuli nemfucumfucu ezindaweni zomoya ze-VFD nezihlungi. Ukugeleza komoya ngendlela efanele kuvimbela  ukushisa  futhi kusiza ukugcina izinga lokushisa langaphakathi elizinzile ngesikhathi sokusebenza okuqhubekayo.

 

 Hlola Abalandeli Abapholisayo 

 

Hlola abalandeli abapholisayo ngezikhathi ezithile ukuze uthole  ukunqwabelana kothuli, umsindo, noma ukuguga . Shintshanisa amafeni angalungile noma agugile ngokushesha ukuze uqinisekise ukunqanyulwa kokushisa okuphumelelayo.

 

 Qinisa Ukuxhuma Kagesi 

Amatheminali axegayo noma izixhumi zingabangela  i-arcing kagesi  noma ukuphazamiseka kwesignali. Hlola futhi uqinise wonke amandla nokulawula ukuxhumana ukuze ugcine ukusebenza okuzinzile.

 

 Gcina Imvelo Ihlanzekile Neyomile 

Faka i-VFD endaweni  engenazo izintuli, eyomile, nengadlidlizi . Umswakama owedlulele, uthuli, noma ukudlidliza kungalimaza izingxenye zangaphakathi futhi kunciphise ukwethembeka kwesistimu.

 

 Buyekeza i-Firmware namapharamitha 

Uma itholakala, buyekeza i  -firmware ye-VFD  ukuze uthuthukise ukusebenza, ukusebenza kahle, nokuhambisana nezici ezintsha zokulawula ukuphotha. Njalo yenza ikhophi yasenqolobaneni yezilungiselelo ngaphambi kokwenza izibuyekezo.
