    I have a problem that I want to control the speed of dynamixel when it change the value. Now it’s too fast and I want it slower. In the “dxl_write_word” function of CM-530 embedded, I try to find which value can help me control it but I can’t. Can you help me figure it out? The thing that I find work the same with “speed rate” in Roboplus motion.
