Hi!

Im getting overcurrent errors when using my battery as power. approx 125V.

I ran the controller on 40V DC and was able to spinn the motor without faults.

I changed the oculim to 100A and connected the motor to 125V, did precharge and connected pin 22 to get into opmode RUN.

Used a normal throttle, hal, and connceted pin 16 to engage FWD.

Motor spins up, maybe 2-3 seconds, low rpm, and the hits OVERCURRENT and opens the contactor.

I the log I see that Iq and il1 are very high:


Any ideas?

Settings:

I noticed that syncofs is 0. Is that correct?

syncofs 0 is a good starting value for the Leaf motor. ocurlim of 100A is a bit slim though, go to 400A for testing and 900A for actual use.

Ok, the first test was done using default settings, think it was 700A, and that hit the roof as well.

can you write "get pinswap" into custom command and then post here the output (above the parameter list)

hmm, thats correct. If you go in Manual Mode and command 1A of d current, what happens?
