OK first disconnect the battery power to the motor/inverter. Let's get the throttle configured right first. Wait, have you had a capacitor connected with the IGBTs during all of this? It's really important not to switch the IGBTs without a capacitor hooked up to them.

OK, look on the board where it says HALL. You need to use the hole called POT (just to the left of HALL connection), as well as the rightmost pin of the HALL connection. Don't use the leftmost 2 pins of HALL if you are using a resistive pot. You will only have 2 wires. So like this:

POT -------------------------------- potentiometer wire #1
rightmost pin of HALL -------------------------- potentiometer wire #2

Then, with the battery disconnected from the high voltage section, stream raw throttle like this:
stream-raw-throttle 1
data-stream-period 1000

Now, again find the range of values for raw throttle. let's say they are:
minimum throttle = 300
maximum throttle = 600

Now, for running the PI tests and rotor time constant test, you need the throttle in the "zero" dead zone. So to create one, go like this (assuming the fake values I just made up):
fault-throttle-position 20 (anything smaller than 300 is fine, but not too close to zero)
max-regen-position 50
min-regen-position 60
min-throttle-position 800
max-throttle-position 820

You want the WHOLE valid throttle range to be in the dead zone (zero throttle).
Before continuing though, do you have the capacitor(s) connected to the IGBTs?

Also, is your induction motor 4 pole pairs? What is the RPM on the nameplate?
