Why do I need to specify current?

Popeye
Associate III

Hi. I'm getting fault after fault trying to get my motor to run. FAQ document says to change ramp-up parameters. Why? Why should I specify any current values? I want the motor to get to a certain speed, and the control algorithm should handle the MOSFET switching and PWM to meet my target speed and be able to adjust it to a dynamic load, right? The FAQ pdf says the ramp should end at 30% of max speed and then 15%? 0693W00000Y9iW0QAJ.png 

I'm using a B-G431B-ESC1 and a 14-pole, 1500KV, 2-4S, 30A, sensorless BLDC.

Would some kind soul please enlighten me?
