Hi,
at the moment I have five servo drives, one for each axis. I have another servo drive for my servo driven spindle that I use for steel, and I have a small VFD for my 800W 24000rpm spindle,
plus the AC distribution stuff including breakers, line reactor for the VFD, and the two EMI filters.

In the near future I'l have another larger 7.5kW VFD for my new spindle. I'll probably retain the little VFD to drive a variable speed coolant pump. In the medium term I'm building another servo
driven 'steel' spindle, say 2000rpm but 20Nm continuous and 100Nm peak. So I'll need space in the cabinet for that too.

All-in-all I need quite a bit of room in the cabinet. You always seem to be adding new bit and pieces and it all adds up.
