Most Huanyang VFD's don't have any components connected to the resistor terminals, so a resistor won't do anything..
Off the top of my head, I think PD014 and PD015 are accelerate and decelerate. I have mine both set to around 2 seconds. It'll stop that fast at around 12,000K or less, but at 24K, it takes about 6 seconds to stop.
