Good morning everybody! I ran into a problem at work. Our Hardinge VMC 1000-II has been giving us problems. As described in the title, we are getting error 449 x axis inv. ipm alarm. When this happened, I went to the back and looked at the servo amp module and it indicated "8.". We just replaced the wires that run from the servo motor to the amp, and I have checked them and found nothing unusual. We have a service tech guy we use, but I'm trying to diagnose as much as I can myself to save some money and time. Does anyone have any suggestions on what to diagnose and check for?
Here are some symptoms: When the alarm trips, it seems like a power surge is sent through the shop. The lights flicker, and the computer that's connected to the machine makes that sound when you plug in or unplug a usb drive. Another possible culprit could be the phase converter that we use. We don't have 3 phase power coming to the shop, so we use a phase converter. Any help would be greatly appreciated! Thanks guys!
