I haven't done many applications with braking resistors, but we just put one in for a customer on a 60HP application for a centrifuge. We're monitoring amps and DC Bus Volts and trying to figure out the best way to maximize the deceleration without tripping the overvoltage. The DC Bus Volts max is 790vdc. We're currently seeing around 740vdc in decel. In theory, when we speed up the decel, will that increase the DC Bus Volts, or is that regulated and we should be watching something else?
