Boat mode implementation

Post by ElMaco »

Hi all you clever people.

Is there anyone that have implemented boat mode in their inverter?

I am running parallell tracks here, both trying to get the "ordinary car mode" working in my boat, and understanding how to implement boat mode, if needed.

In other threads/topics I have gathered some bits and pieces. But there is still plenty I don't understand. Such as, is pot-mode bidirectional a requirement for boat mode, or is it an option?

We have a Curtis ET-134 FNR and throttle combi controller installed in the boat, which I am trying to use. In parallell I am getting help piecing together an arduino that will convert signals from the combi controller to CAN messages. Question is which signals/messages/values I should convert to, to make things as simple and stable as possible.

All knowledge and experience about boat installations in general, and boat mode in particular, are appreciated :)

Ok, I said I'm stepping away from inverters but I'm afraid nobody else knows this. Of course the code has all the answers :)

Boat mode has two options
a) throttle input is not treated as a torque command but as a speed command (cruisemode=ThrottlePot)
b) Throttle is center aligned, pulling it back puts direction to reverse, forward to forward (potmode=BiDir or CANBiDir)

The two can be but don't have to be combined
