VESC ramping problem

Hello,

I am having trouble with the VESC firmware in BLDC mode. When I change the input duty cycle from 0 to let's say 50 instantaneously the ESC is failing to commutate. The VESC firmware should have a ramping function that ramps up the motor in steps. I tried decreasing the duty cycle used for ramping step from default 0.02 to 0.001. But it seems that the ramping is too slow now. Has anyone experianced a similar problem?

 

Thanks.
