Do you have 240V 3 phase where you are installing the machine?
not only do I have a small rotary phase that I use for the conversional milling
I think you need a 10 HP rotary phase converter and a 240/480, 15 KVA, 3 phase transformer. That would be the easy way to make it work.
Check to see the spec's on the VFD say 480V this is the only part and spindle motor that will need the 480v if it is a 480v machine check the transformer T1 and T2 these can normally be configured for 240V but the VFD and spindle motor wiring may be where you have a problemQuote:

I'm trying to upload a photo but it will not let me try later
That is good news then you can get to running on 240v single phase then I will tell you how once I see some more photos, you posted photos before so should work the sameQuote:

That is kind of strange that it has the 230v VFD Drive and 480v on the machine spec's I think someone must of changed it to a 240V machineQuote:

Check your Power supply 240v is what NA should be sometimes it is higher or can be lower, what is your supply voltage ???
You then set the T1 and T2 Transformer jumpers to this Voltage if it is not already set
230v setting would be for T1
245v would be for T2 if your power supply is up there in the 240v range
Don't connect your RPC these machines do not like Rotary Phase Convertors
Another thing to check is the coolant pump most are single phase just check this in your first schematic it is showing it as 3 phase supply for the coolant pump, what is yours and is it wired the same as the schematicQuote:

if it is something strange because the vfd is 230v and the spindle motor says 400v
I think the single phase current is 240v I have to measure it to see how much it gives me
the coolant pump is single face 120v

Are the Transformers wired for 230v T1 and 245v T2 this is important
greetings I could not answer but I'm back the voltage in my house is 230v and configure both transformers to 230v and I could turn on the electrical panel without turning on the VFD or the spindler since they are 480v consult with those of Bptparts.com and I They said they were 480v
it's already on but I'm having a problem when I give the drive the enable it is giving me an alarm (Axis Drive Fault) that could be causing this failure
Thanks
for the spindle and the VFD I will have to install a transformer 208 to 480v
You need to connect your mains Power 230v supply to L1 and L2 then Jumper L1 to L3 this won't run you VFD drive because of the 480v needed but the rest of your machine should run, the transformer may cost a lot as well you may find a 230v VFD Drive that is cheaper, check to see what the spindle motor voltage is it may be 200v to 480v so just changing the VFD may work if the motor wiring can be changedQuote:

Turn the VFD Drive on then it won't hurt the VFD drive may give a low voltage alarm though this way you should be able to check the machine homing Etc.Quote:

ok thank
I'm checking a step up transformer 208v to 480v
I know this is an old thread, but did you get anywhere with this 480v torq cut?
