Ku rharhangana ko sungula ka ku lulamisa i xihinga lexi xiyekaka, lexi olovisiweke hi tidyondzo.

 

Hi ku komisa, ti-VFD ta CNC ti nyika vulawuri bya rivilo ra granular hi ku cinca-cinca frequency, leswi endlaka leswaku ti-CNC ta desktop ti kota ku langutana na switirhisiwa swo hambana hi vukheta na vukorhokeri.

Eka tisisiteme ta ku vatla, ti VFD ti endla leswaku  ku vatla hi rivilo lerikulu na vuxokoxoko lebyinene  hi ku hlayisa ku rhendzeleka loku nga cincekiki ka spindle. Leswi switiyisisa mbuyelo wo olova, wo kariha, na lowu kongomeke eka switirhisiwa swofana na brass, acrylic, na stainless steel.

 

 Switsemi swa Plasma swa CNC 

Eka switirhisiwa swo tsema plasma swa CNC, ti VFD ti tirhisiwa ku  lawula ku tlakuka ka tochi, mpimo wa swakudya, na ku famba ka ku tsema . Ku lawuriwa ka rivilo loku tiyeke swi pfuneta ku hlayisa vuenti byo tsema lebyi nga cincekiki, matlhelo lama tengeke, na ku tirhisiwa kahle ka eneji hi nkarhi wa ntirho.

 

Kusuka eka ku tirha hi mapulanga kuya eka ku endliwa ka nsimbi, ti CNC VFDs ti tlanga xiave xa nkoka eka ku ndlandlamuxa  ku kongoma, ku tirha kahle, na vulawuri  eka tinxaka tohambana hambana ta michini ya CNC. Kungava ku tsema, ku sila, kumbe ku vatla, kutirhisiwa ka VFD switiyisisa  matirhelo ya kahle ya spindle  xikan’we naku  tshembheka ka nkarhi woleha  eka tisisiteme ta manguva lawa ta CNC.

 

 Switsundzuxo swa Nhlayiso wa ti-VFD ta CNC 

 

Ku hlayisiwa loku faneleke ka  CNC Variable Frequency Drive (VFD) ya wena  i swa nkoka ku tiyisisa matirhelo lama tiyeke, ku hunguta nkarhi wo yima, na ku engetela vutomi hinkwabyo bya sisiteme ya wena ya CNC. Leswi VFD yi tlangaka xiave xa nkoka eku lawuleni ka rivilo ra spindle motor na torque, ku yi hlayisa yi ri eka xiyimo lexinene i swa nkoka swinene eka matirhelo ya muchini lowu tshembekaka.

Landzelela magoza lawa ya phurofexinali hi ku tlanga hi mali y xa le henhla, wo olova lowu endleriweke ku tirha hi ndlela yo tshembheka eka switirhisiwa leswi lavaka.

 

 Hlantswa Swipfalo swa Moya na Swisefo 

Nkarhi na nkarhi susa ntshuri na thyaka eka swipfalo swa moya na swisefo swa VFD. Ku khuluka ka moya loku faneleke swi sivela  ku hisa ngopfu  naswona swi pfuneta ku hlayisa mahiselo ya le ndzeni lama tiyeke hi nkarhi wa ntirho lowu yaka emahlweni.

 

 Kambela Tifani to Pfuxeta 

 

Languta ti cooling fans nkarhi na nkarhi ku vona loko  ti hlengeletana ritshuri, mpfumawulo kumbe ku onhaka . Cinca ti fans leti hoxeke kumbe leti onhakeke hiku hatlisa ku tiyisisa ku hangalasiwa kahle ka kuhisa.

 

 Tiyisisa Swihlanganisi swa Gezi 

Ti terminal leti ntshunxekeke kumbe swihlanganisi swinga vanga  arcing ya gezi  kumbe ku kavanyeteka ka signal. Kambela no tiyisisa swihlanganisi hinkwaswo swa gezi na vulawuri ku hlayisa matirhelo lama tiyeke.

 

 Hlayisa Ndhawu Leyi Baseke Ni Yo Oma 

Nghenisa VFD endhawini  leyi nga riki na ntshuri, leyi omeke ni leyi nga riki na ku rhurhumela . Ku kufumela ngopfu, ntshuri kumbe ku rhurhumela swinga onha swiphemu swale ndzeni naswona swihunguta ku tshembheka ka sisiteme.

 

 Pfuxeta Firmware na Tipharamitha 

Loko yi kumeka, pfuxeta ya VFD  firmware  ku antswisa ntirho, ku tirha kahle, na ku fambisana na swihlawulekisi leswintshwa swa vulawuri bya spindle. Minkarhi hinkwayo endla backup ya swiyimiso swa vuhlanganisi u nga si endla ku pfuxetiwa.
