Hi all
I need some help choosing a VFD for a CNC Jr please.
I know the one that was on it previously was a Leeson AC. It needs to take single phase 230v from the wall and convert it to 3 phase - not sure of the output voltage requirements.
The recommended replacement (by the previous owner) is a Lenze SMD 1.5Kw
What I'd like to know is; could I be using this opportunity to upgrade to a better VFD? What sort of features should I be looking for? What sort of VFD will be compatible with the existing control board, any?
I have a budget of around £200. I know that some features I would like would be for the spindle speed to be a) programmable (to take into account gearing), b) CAM controllable dynamically and c) able to compensate for slip. There are probably features you can recommend that I don't even know exist.
I don't know much about VFDs, for all I know most VFDs can do what I need them to but I have no idea. I would really appreciate some help.
Thanks in advance
