I'm having the same issue.Jonr wrote: ↑Fri Sep 23, 2022 3:47 pm Thanks for that. After hours of trying, the wifi connection to the "inverter" SSID finally stayed up long enough to allow me to load a working prior version. Once done, the wifi access stabilised and the motor behaviour reverted to the smooth operation - all good.
The question I wanted to get to is with regard to the relays/contactors. Following the start sequence of:-
1) Power on
2) Ignition on
3) press start
At what point should each relay/contactor be energised?
I'm guessing that on power on, they are all closed
At ignition on, the negative contactor, precharge and inverter power relays/contactors all activate
At "engine start", the positive contactor is activated and the precharge contactor opens.
Is the above correct?? - The problem is that on my system, when ignition is enabled, no relays/contactor are engergised
But, when the "engine start" is pressed, all relays/contactors are enabled at once.... that seems a little wrong !
Can someone enlighten me to the expected behaviour?
The inverter power relay does not energize until the start button is pressed, along with the contactors.
Then my opmode goes to run, the throttle commands torque.
I have 60V coming out of the contactors, 12V from the inverter relay.
But invudc is 0 and no spinning
