I'm looking for info from excitech atc cnc owners i need to know the spindle and vfd inverter parameters.
Now i have a Delta VFD-B class inverter and HSD 6.5Kw spindle(italy, no atc). And i wanna upgrade to a 7.5Kw HSD spindle (atc system) but i don't know if my VFD will work. The VFD i have can handle 7.5Kw but the max. output frequency is 400Hz and all the HSD spindle (atc system) ar working at 800Hz.
If someone has a ideea pleas share

Hi Mecanicu:
pls check your delta inverter's version. Maybe you are going to change HSD ESE929 and it has a 4 poles motor, and you'd better ran it 24000rpm, 12000rpm is not good. for the delta inverter(VFD-B) have different version, some can change to 800hz, some cannot, and all their default value is 400hz.
check it and send me an email: [email protected]. if it is the right version, i tell you how to change the parameters.

Alan
