Hey Owen,
thanks for the photo of VFD nameplate.
What it says is:
- The VFD can deliver 180-250 V 3-phase current with 15 A at its output,
but - the rated 10 A at its input is obviously the value for 3-phase input, which means, per phase. You have a VFD model that you can attach on single-phase or on three-phase electricity. Unfortunately the rated input current for operation on single-phase electricty is not mentioned on your nameplate.
But if you look at my nameplate on a VFD with the same parameters (by coincidence) I know that if you use it on single-phase supply, the maximum input current would be about at least 20 A.
By coincidence the values of your spindle and your VFD both correspond to mine, except that my VFD is offered for one phase input and for three-phase input as separate models. Since in Europe we usually have either three-phase electricity with 400 V or single-phase with 230 V, the 200 V three-phase model is of no use (it suits U.S. 208 V industrial three-phase electricity), so you have to use your VFD with 230 V single-phase if you’re in Europe.
What unfortunately is not mentioned on your nameplate, is the max current if you use it with one phase input. On my VFD, which is also a 200 V class, 2.2 kW VFD with single phase input, it is rated with 20 A max. input current in CT mode and 24 A in VT mode.
You can see in this table that the 200 V class 2.2 kW (CT mode) version on single-phase input requires a 30 A fuse (a one-phase MCCB), but the same model with 200 V class three-phase input, you need only 15 A fuse, but that is one fuse per phase(!), which means that would be a 3 x 15 A MCCB. This way you can judge on what the 10 A input on your VFD means, it means, per phase, if you would have three-phase input. But on one phase, it is logical that it would have more rated ampères since all the power would come from one single wire, thus the need for larger current, larger fuse and thicker wires then. Wire and fuse size do not depend on input power (kVA), but on current (in ampères)
That means that at its input, I have 2+PE × 4 mm² cable and at the output for the 2.2 kW / 8 A three-phase spindle, I have 3+PE × 2.5 mm² shielded wire.
For the VFD with 20 A input on one phase, this means the usual 16 A household circuit is not enough, so I have a Blue P+N+E 6h/32 A CEE wall outlet (see image in posting below) on a 32 A one-phase MCCB.
I think it’s very okay to buy the cheap spindles and VFDs if you are new and want to get in contact with the matter. The reason why I don’t always mention what I bought is that it will break the bank for many hobbyists, but I plan to use the equipment professionally. What I bought is decribed here:
Note that I would not buy the Omron MX2 in its single-phase version again, but always prefer the version for 400 V three-phase input. But at the time I bought my stuff the three-phase 400 V model was not available. We have 400 V three-phase in every house here (in the circuit breaker box). This would have allowed me to use thinner cable at the input (3+PE with 2.5 mm² wire size instead of 2+PE x 4.0 mm², and a 3 x 16 A MCCB instead of a 1 x 32 A MCCB).
Note that the Omron MX2 is practically identical to the Hitachi WJ200, also the manuals are nearly identical (Manual / Manual). The 200 V class one-phase input 2.2 kW model that corresponds to Omron 3G3MX2-AB022-E is Hitachi WJ200-022SF.
By the way the same spindle I bought is already in use by two forum members here and the Hitachi WJ200 also by two people.
