Motor & Inverter

Well, well, well. I finally got the inverter fixed and got the inverter re-programmed. Now I can re-program if any updates come available. There was one thing stumping me and that was the emergency stop function. It kept coming up as zero and it needs to be a 1. 1 means the inverter has not been stopped and is good to go. The original inverted I purchased did not have that wire connected and it needed to be connected to a high voltage of 7 volts or higher. God only knows how it ever ran with that always being in emergency stop mode. The wire was never connected at all. So, I got it connected now to 12 volts to keep it high. No need for an emergency shut down. Well, maybe I can setup a 12 volt switch and use that for a table top emergency shut down if I happen to have to shut it down fast. That should be an easy thing to wire up. So with that, I was able to get the motor to run again and even run in Start Mode 2 which I was never able to do before. I now have to re-charge my battery so I can do some more testing. Its on the charger now and happily charging at 15 amps. Once I have that done I will need to get the inverters heat sink working. Its a water cooled sink and it got hot doing a bit of running at 37 amps. Now to move along and set some parameters to tweak the inverter to the motor. Im only running 12 volts so that will have to change soon. I need to get a good 12 volt pump for the cooling system. Time to hit Jack up for one of his pumps for folks who have water cooled sinks. So I did a quick video with the motor running albeit roughly in Start 1 Mode and Start 2 Mode. I am moving forward once again and have learned a crap load of stuff about flashing a chip with software. It took a bit but I got through it with the help of Johannes Huebner.
