Hi Steve,
The VFD is a GE/Fuji AF300 G11!
I just got it back on Friday from a place that troubleshoots VFD's as well as sell them! The company found the answer to a fault code which had to do with a thermostat! They checked all the parameters set on the VFD for my spindle and told me they were all good to go!
This is a retrofit of a Vital Systems Hicon, matching drives and servos to replace all the old outdated drives and servos as well as a discontinued controller by the name of AMC from England. Company is out of business, controller no longer made or supported by Onsrud! No parts, no software etc. This is the VFD that came with the machine and the spindle! The spindle is a 10hp Colombo air cooled.
