I have a 56V odrive with two Turnigy Aerodrive SK3 - 6374-149kv motors hooked up. They are using cui 8192 encoders.
No matter what I do the bus voltage seems to be reported as 26 ish volts. I’ve verified with a multi-meter that the bus voltage is 48V.
I am unable to get the bus voltage errors to clear. It seems like the board came configured for 24V, so I was getting over voltage errors. After changing the following I’m getting under voltage errors:
dc_bus_undervoltage_trip_level = 42.0 (float)
dc_bus_overvoltage_trip_level = 50.400001525878906 (float)
Here is the output of odrv0
