There should be a "P" and "N" terminal. THAT is the connection for the external braking resistor on your Huanyang.
BTW, another point- I have seen (but not worked with) a "DC brake" feature on both my X200 and your Huanyang. I believe that's because regen braking becomes much less effective at low RPM. It injects a DC current on the winding which causes considerable additional drag on the core at low RPM. But, like I say, I haven't tried it out. There are warnings about overheating the spindle's poles if the current is specified too high or for too long.
