Have you respected the battery cable length referred in the manual?
Also there's a lot of stuff talking about 5V, everything according to the manual also?
Is DC coming from a battery, power supply, both, any caps in parallel... ?
Have you tried to fully disconnect the generator setup and just run the motor?
Have you tried using both controllers to serve as motor controllers? Same errors glitches?
Quality serial cables with decent EMI insulation?
Yup, used the cables already provided on the controller which were to spec, hooked it straight to supply.
Initially I used another power supply to give the controllers 5v. But later just let the internal DC/DC handle powering the controller.
10Kw supply, going to hook another one in parallel in the coming weeks to drive it to spec.
Yep initial test was single motor with no load.
As far as I can tell yes. So with the next test we're going to run with the motors we're just going to use rs232 for data, and use analog control.
Could always use better serial cables. But I wouldn't expect seeing the same two faults again and again. (even though it was less than 10 times)

Try to get solid control of a single motor first.
Even when controllers just share a battery and otherwise get fully isolated signals, Ive seen wonky throttle behaviors. I think it's gotta be ground loops in the main power bus.
God no, not the ground loops again. Had an absolute nightmare with my Emrax setup.
So if anything I'd tie the grounds coming out from the serial ports together to have a more stable ground? Both motors already using the same power supply, connected to same computer controlling both motcos. Only serial Tx/Rx being used to communicate to motcos. Every other pin left alone, and isolated.

How can I see this in English?
Google translate, or find yourself a German
Either way I do not like how the serial communication is working out. I'm just going to place my controller for analog signal as close to the rs232 ports on the motcos as possible, shield the crap out of everything and call it a day.
