KV58 to control BLDC with hall sensors

I am using KV58 to control BLDC with hall sensors and have the following issue:

1) I am trying to use the ramp control to add the power slowly and causes the motor start-up problem. Sometime, I can't start motor even with full power applied on it. When it is the low power, motor keeps bouncing back and force...

2) If I applied full power and no ramp control, it works fine...


Does anybody have experienced the similar issue and how to fix it?
