Looking for some help with my BMC-40. I have been getting an "Servo Driver Fault on Axis S" error when my tool is done with the cut and is retracting to make a tool change. It seems to be the tools that have the rpm over 1000. It almost seems that the brake is failing somehow. But when it does its' retract, it faults out, shuts the spindle down and free spins to a stop. The error on the screen (Ultramax 3) reads Servo Driver Fault on Axis S". The LED error on the drive board in the back reads "OV" for over voltage. The Serial # is BL-9002090A on machine and NS80581-005-1 on drive cabinet. Manufacure of the drive Starts with a Y. I have a picture of the drive but I do not know how to post it. There were some guys that had similar problems in this forum but never posted how their problem was solved. Any info or help would be greatly appreciated. Thank you.
