Hello all. I am in need of assistence with my MV-40's 4th axis. I need to remove it from the table for repair, but whenever I unplug it, I receive Alarms. The Alarms are (390 servo pack (SR 20) and (310 servo off). My controller is a YASNAK MX-3. Our local tooling repair company has also tried unsuccessfully to remove it. It seems the main parameter is #6023 D6 which I believe should be set to "1". There seems to be something else needed to complete the 4th axis neglect signal and allow me to unplug the cables.
