VESC at very low speeds

For a project, we need to drive a brushless motor at very low speed. yet with some torque at very low speed (almost like with break on)

The ideal thing would be that VESC always generate a sine waves but at frequencies of 50Hz down to almost 0. Were it would be similar to brake...

I have realized that at very low speed, the motor is turned OFF. The signal also does not look like sine wave.

What settings would you recommend ?

Thanks
