Update:
The controller appears to be OK. My power-up sequence is turn on separate 12V to the controller and wait for the clicks, turn on pre-charge, turn the key on for the Polaris Ranger EV, wait for the built-in SEVCON controller to close the internal contactor, then turn on my external contactor.
Bus voltage is 56.1V, with B- at 0 and B+ at 56.1V THIS TIME!
I logged the config and started logging data once per second. I ran the driven tires backward and verified that the mechanical motor speed was registering.
The I did RUN-PI-TEST. And I waited. The motor started making pulsing sounds after maybe 5 minutes. And it went on .. and on .. and on ...
After 2 HOURS it was done. It may have been only an hour and 45 minutes ... I just checked on it once in a while.
Attached picture is hard to read. The error message is:
P I Overflow fault. It's really not tracking IdRef and IqRef well at all.
So tonight I will spend a few minutes and see if I can get the motor to try turning by faking the throttle signal. I'm gone for the weekend so it will be Monday before I get the firmware upgraded so I can see what is going on with RUN-PI-TEST2
*BUT THE CONTROLLER IS OK*!! Whew!
Maybe I should see the tires rotate before I declare victory?
