CNC Variable Frequency Drives (VFDs)  bɛ baara kɛ kosɛbɛ CNC masin suguya caman na walasa ka  motɛri kɔlɔsili tigitigi , teliya labɛnni ɲuman di ani  baarakɛcogo min bɛ fanga dɔgɔya , Ni VFDw ye frequency ni voltage ladilan min bɛ di spindle walima moteur ma, o bɛ se ka kɛ sababu ye ka masinw kɛ ka ɲɛ, ka u yɔrɔ cogoya ɲɛ, ani ka minɛnw si janya.

CNC baarakɛcogo minnu ka ca VFDw la, olu bɛ duguma:

 

 CNC Routers (Routeurs CNC) ye 

CNC routeurw kɔnɔ, VFDw bɛ  spindle teliya kɔlɔsi  walasa ka fɛnw tigɛ ani ka u ja i n’a fɔ  jiri, plastiki, akiriliki ani aliminiyɔmu . O b’a to baarakɛlaw bɛ se ka sɔgɔli teliya ni fɛn gɛlɛnw ni tigɛminɛn suguya bɛn ɲɔgɔn ma, o bɛ kɛ sababu ye ka dakunw nɔgɔya ani ka finiw saniya.

 

 CNC Milling Machines (Mɔgɔw ​​ka baarakɛminɛnw). 

VFD minnu bɛ CNC sɛnɛfɛnw dilanni masinw na, olu bɛ  teliya kɔlɔsili caman di  nɛgɛ masinw dilanni tigitigi kama. U bɛ sira di  daminɛ nɔgɔmanw ma, teliya kɔrɔsilen, ani girinya ladilanni , o b’a to tiɲɛni ka bon ani baarakɛminɛnw sɛgɛnni dɔgɔyali mansin baara gɛlɛnw senfɛ.

 

 CNC Jatebɔ Masinaw 

Jatebɔ siraw la, VFDw bɛ se ka  ja teliya ni fɛn fitininw ja dilan,  u kɛtɔ ka sɔgɔlilan jiginni sabati cogo basigilen na. O bɛ kɛ sababu ye ka jaabiw sɔrɔ minnu bɛ nɔgɔya, minnu ka nɔgɔn, ani minnu bɛ kɛ ka ɲɛ fɛnw kan i n’a fɔ nɛgɛ, akiriliki ani nɛgɛ min tɛ sɔgɔ.

 

 CNC Plasma Tigɛbagaw 

CNC plasma tigɛlanw ta fan fɛ, VFDw bɛ kɛ ka  tasuma janya, balo hakɛ, ani tigɛ lamagacogo kɔlɔsi . Teliya labɛnni sabatili bɛ dɛmɛ ka tigɛcogo juguya sabati, a dakunw saniyalen don, ani fanga baaracogo ɲuman na baara kɛtuma na.

 

K’a ta jirifeere la ka se nɛgɛ dilanni ma, CNC VFDw jɔyɔrɔ ka bon kosɛbɛ  tiɲɛni, baarakɛcogo ɲuman ani kɔlɔsili yiriwali la.  CNC masin suguya caman ka A kɛra tigɛ ye wo, a kɛra sɔgɔli ye wo, a kɛra ja ye wo, VFD baara bɛ kɛ sababu ye ka  spindle baara kɛcogo ɲuman sɔrɔ  ani  ka dannaya kɛ waati jan kɔnɔ  bi CNC sigidaw la.

 

 Ladilikanw ladonni kan CNC VFDw la 

 

Aw ka ladonni ka ɲɛ  CNC Variable Frequency Drive (VFD)  , o nafa ka bon walasa ka baara kɛcogo sabati, ka baarakɛbaliya waati dɔgɔya, ani ka aw ka CNC sitɛmu ka ɲɛnamaya bɛɛ janya. Ikomi VFD jɔyɔrɔ ka bon kosɛbɛ spindle motɛri teliya ni a girinya kɔlɔsili la, k’a to a cogo ɲuman na, o nafa ka bon kosɛbɛ masin baara la min bɛ se ka da a kan.

Aw bɛ nin ladonni fɛɛrɛ nafamaw labato:

 

 Aw bɛ fiɲɛbɔyɔrɔw ni filɛriw saniya 

Aw bɛ to ka buguri ni nɔgɔw bɔ VFD fiɲɛbɔyɔrɔw ni a filɛriw la. Fiɲɛ bolicogo ɲuman bɛ  funteni kojugu bali  ani ka dɛmɛ don ka kɔnɔna funteni sabatili sabati baara kɛtuma na.

 

 Aw bɛ Cooling Fans lajɛ 

 

Aw bɛ nɛnɛbɔlanw lajɛ tuma ni tuma ni  buguri tɛ u la, ni mankan tɛ, walima ni u sɛgɛnnen tɛ . Aw bɛ fiɲɛbɔlan tiɲɛnenw walima minnu sɛgɛnnen don, aw bɛ olu falen joona walasa funteni ka se ka bɔ ka ɲɛ.

 

 Aw bɛ Kuran Jɛɲɔgɔnyaw siri kosɛbɛ 

Terminal walima connecteurs lafiyalenw bɛ se ka kɛ sababu ye ka  kuran arcing  walima signal interference. Aw bɛ fanga ni kunnafonidilanw bɛɛ sɛgɛsɛgɛ ani ka u siri walasa ka baara kɛcogo sabati.

 

 Aw bɛ sigida saniyalen ni jalen mara 

Aw bɛ VFD bila yɔrɔ la  , buguri tɛ yɔrɔ min na, yɔrɔ min jalen don, ani yɔrɔ min tɛ yɛrɛyɛrɛ . Nɛnɛ kojugu, buguri walima yɛrɛyɛrɛ bɛ se ka kɔnɔnafɛnw tiɲɛ ani ka dɔ bɔ sistɛmu dannaya la.

Ni a bɛ sɔrɔ, VFD ka  firimiwɛri kuraya  walasa ka baarakɛcogo, baarakɛcogo ɲuman ani ka bɛn ni spindle control fɛɛrɛ kuraw ye. Aw ye labɛncogo labɛncogo kɔpi kɛ tuma bɛɛ sani aw ka fɛn kuraw kɛ.
