MOLLOM VFD 5.5KW 7.5HP 25A 220V Single or Three Phase Input to 3 Phase 0-3000 Hz Output Variable Frequency Drive Control Inverter for Spindle Motor CNC Speed Control

I am in the UK and needed to convert my 1974 Colchester Student lathe from 3ph (2.2kw) to run off 240v 1ph. I chose the 5hp (4kw) version Mollom VFD as the lower power ones were not available at the time. I have wired it so the lathe control stop/start/reverse go through the inverter to control it as original lathe set up. I emailed the seller and they sent me the parameters. I did have questions and the tech support (which I assume is in China) was answered with expert knowledge within 12 hours so next morning a reply was waiting. I am a professional user and wanted to use the lathe for a couple of months and can report no problems what so ever. If your converting your 3ph spindle machine then I highly recommend Mollom for the VFD. Due to the higher KW rating I assume I was able to set the acceleration and deceleration times to 3 sec and 2 sec respectively without any over load problems. A lower kw VFD may well have needed a braking resistor wired in. As a cautionary note, not all 3ph motors can be converted to 1ph VFD so do your homework first.
