Everybody has been scratching there head about this one.....
I have a 1995 VF-4, with a 10K spindle and a mitsubishi spindle drive. This machine is in very good condition, having never been in a manufacturing environment.
After pulling a piece out of the vise and causing a noise in the transmission-I had Haas come out to repair the machine. They installed a new motor, transmission and 10k spindle.
After the repair I started getting alarm code 123 (spindle drive alarm) at around the 700 rpm range. The fault code on the drive unit is E.0C2 (overcurrent shut off-constant speed).
The Haas techs have been here six times now just for the new alarm-with no success. Any ideas about would be greatly apprciated. Thanks.
