I have designed a board similar to B-G431B ESC1 kit and using the FOC code from the motor control work bench. But at present i have an issue where the Gate to Source Voltage is equal to Bus Voltage (VDC) instead of the 12V. What could be the problem? The Mosfet driver IC i am using is 2ED2182S06FXUMA1.

The problem is because of the below setting in motor control work bench

I have now updated to 20ms and it works i have kept the charge boot capacitor duty still to 0%, i plan to change that as well to 50%. I am not sure which value to be kept.
