Is it 415V only?
100Hz might be a little much to ask of it only running at 240V, wouldn't know haven't tried that.
yes, it's only 415V, will look into getting another motor.

using a 3kw VSD connected to the UVW1 motor terminals which i believe is the slower speed, 700 rpm and from memory around 1.5KW.
if it's the higher speed then i need to change the motor parameters.
( hope it's a 3KW VFD, as there is no model number or even the huanyang brand anywhere on the inverter.)

ran the lathe in the higher gear and left it on to see what happens,it speeds up, then gradually slows down to a stop. even stranger is the spindle speeds up for a short time when turning it off just before the spindle stops.
( this only happens in the higher gears due to it slowing down after reaching a certain speed).
