Re: Chinese spindle with Fuling inverter

do basic test of the vfd with DC voltage when NOT connected to the Acorn.

how many RPM at 1.5 volts (house hold battery) ? how many RPM at 9 volts? etc.. and then go from there.

updated VFD calibration guide attached. marty has nice videos as well on this subject.

Re: HITACHI SEIKI LATHE RETROFIT

you might want to pay Terry at Arrow some consulting money on this one.. he has lots of experience with these older yaskawa drives and can tell you what will work and what won't. https://www.facebook.com/Arrow-Controls ... 279118218/
