D vs omega control

Apologies if this is a basic question, but I can't seem to find the answer anywhere.

I've got an FOC application. Under the FOC menu I have 'Encoder' chosen as 'Sensor Mode', but then under the Encoder tab the 'Sensorless ERPM' is set to 4000, which is lower than my min, so I believe that means it's running sensorless all the time?

My question is regarding the D and ω fields. I've tried using each of those for controlling my motor, and I've noticed some differences between them. Specifically:

motor stops spinning on its own

Just got a VESC HD-60T yesterday and after following the set-up wizards in VESC Tool was able to get my motor spinning without too much trouble.

I don't have any remote control hardware (in my final application I'm planning on using CAN), so in the meantime I'm trying to do some motor testing purely over USB using the RPM and D settings at the bottom of the VESC Tool window to get the motor spinning at different speeds.

Throttle and Brake

I have a Ninebot Max scooter.  I replaced the ESC with a VSC.  Is the throttle 3.3 or 5v?  Is the brake 3.3 or 5v?  I have a 13s6p battery.  The app is asking me how many amp the batt is.  Each cell or total pack?  Also, I have a 12 LED light i want to hook up.  There is 12v, gnd, and AUX.  What is the AUX term for?

Been at it for like 14 hours... HALP

I have been trying for (no joke) like 14 hours to get my new Flipsky VESC working with my Esk8.  I have followed the instructions to a T as far as I can tell.  I cant find anyone who can help.  I know for  fact my battery and motor are good. If anyone is near Manchester NH I will pay you to come fix this or if someone is a whiz, I will screenshare with you and you can take control.  PLEASE HELP.  I am very frustrated and discouraged with this.  Feel free to text me if you think you can help six oh three 5 oh 5 69 five9

RPM increase

How can I increase engine RPM?
At 200mm in diameter, a 28-pole BLDC motor does not rotate faster even though I increase the e-rpm value (Flipsky Vesc 4.2 50A).
Battery is: 13S 6P lithium ion, 48V 15Ah

What do I do wrong? 
Thanks all answers.

How do I disable brake?

I'm using the 4.12 FSESC controller in a tracked vehicle, and need to disable the brake. Can't find any settings to disable the current-hold when its in neutral. How do you disable regen brake, or braking of any kind? My application needs to be able to coast when its in neutral.

FSESC 6.6 200A Unable to send signal to slave VESC

I have been up and down looking for what I'm doing wrong or what isn't configured correctly. I am using a 5kohm potentionmeter to supply a ppm input through an arduino to the VESC. the vesc tool that I got from this website is 3.00. There are two micro usb ports on the vesc, and I have figured out which one is the master. I have succesfully gotten one to fully respond to the input from the potentiometer. However, this is where everything goes wrong. This version of vesc tool doesn't have the input setup wizard that allows for a master/slave vesc configuration.
