vesc for helicopter tail rotor / freewheel for duty cycle mode

Hello. Can you help us with the following issue:

We are going to use VESC for driving tail rotor in helicopter. Tail rotor has foldable blades.

It is absolutely necessary to drive in duty cycle mode with no braking. The main reason for that: blades can make vibrations or even fold during braking.

What i tried for now : setting motor and brake current 0, and it did not help.

What else can i try ? Change parameters or may be some modifications to the code can be done?

You should be able to set the battery regen current to 0, or very close to 0 to get no braking. Although sometimes you can then end up with uncontrolled acceleration with very small loads.

Vesc could be completely bring to OFF mode by grounding DRV's EN_Buck pin, or Switching-off it's power-supply.But if it is regenerated, it can wake-up.
