Depth Hold not working

I have an OpenROV 2.8 and have installed the IMU-Depth Module. All is working OK apart from the Depth Hold function. When I set in on, the vertical motor activates and brings the ROV to the surface. Is there a minimum depth for this to work, or am I missing something?



Answer this question I have this problem too

Is this a good question?

It sounds like you have the vertical motor reversed. When you are operating the ROV when you press the "CTRL" key the ROV should go down and when you press the "SHIFT" key the ROV should come up. You can switch the direction in the "Diagnostics" tab of Cockpit. If the direction is backwards the control loop for the depth hold will not work properly.

Hope this helps.
