[DG] [DG11] DRIVE STOPPED troubleshooting

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum alx,

The reported symptoms would not be associated with a software problem. The symptoms reported are those of an ACU has interfaced to a load which exceeding the design of the ACU or an ACU which is failing. As the ACU's components heat up in response to the load, the time between such drive stop failures would be expected to decrease should the system be restarted. Continued use may lead to complete failure of the ACU. When recommending an ACU for use with a third party rotary drives, an ACU400 would typically be recommended.
