backdrive value for overriding Victor dynamic brake

[4AngryNutjobs]

Hey guys,
I'll cut straight to the point. We are using a Victor motor to power an elevator lift and we would like to slow the lift on its way down, so we turned on the brake for the Victor motor. But when we turned on the brake, it runs too slowly down. So we're backdriving the Victor motor to make it run faster, we just don't know if the dynamic brake works as a generator and if there's a "perfect value" for the back drive, or if it's just an on/off thing. Any input would be greatly appreciated
