Hello All,

we have a Matsuura MX760 with Yasnac MX3. It came installed with a 4th axis drive and rotay. The 4th axis servo drive died, and we never use it, so I want to disable the 4th axis completely and just run it as the traditional 3 axis mill. How do I go about this? I found some parameters that seem like they would do the trick, but it still is telling me "ALARM 390 - SERVO ALARM (SERVO PACK) (SR20)

Any ideas?
