Need to remove 4th axis from MV-40!

[Prism Maker]

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.

Try this.
It's for an MX-2.
Should be close.
