Hi all .

I was just delivered a machine that has an inverter built in to variable power the motor. The inverter has a 3 phase 220 in. We have 220 but we don't have 3 phase.

The inverter is a Lenze inverter in the machine and they mention you can connect this to a single phase line but the machine will run at 50%.

Question is... What lines to connect to the single phase? I have wires labeled Nuetral, Phase #1, Phase #2, Phase #3 and ground.

I assume ground and neutral as is and then Phase #1 to hot?

Any other suggestions apart from bypassing the built in inverter and wiring in a standalone single phase to 3 phase inverter? Rotery will probably be super pricy I think to power this bad boy . Looking for a budget but good way to do this.

Thanks

In the majority of cases the input pair does not matter as the input is generally connected directly to a 3ph bridge.
The neutral should not be required, in N.A. just L1, L2 and GND.
If you are in IEC or Australia etc then it would be L1 & N.

On that cutter label.....it looks like the manufacturer's phone number. Why not call them and ask?

 

The manuals show that the 230v 1ph models connect to L1 & L2 often labeled R & S of R,S,T.
