Delta VFD Drive

[rrbmachining]

We have a 3 phase drive type Delta VFD075B-023A which is a 230v 3 phase type for US supplies. Our supply here in the UK is 415v 3 phase. So this drive will not work on our supply. The machine supplier (Lehigh) have told us to wire the machine for 230V single phase and assure us the Delta drive will work fine. Has anyone got this type of set up running. We dont want to blow up another VFD drive. Any help would be appreciated

Check the manual, it will say if it accepts single phase or not, most do now up to 5hp~7.5hp.

the deltas only support single up to 3hp if i remember. the manual should be available online. i had a 1.5hp delta vfd on 220 single. basically you just connect 2 wires instead of 3 to the power input.
