####Does it work with DC Servos? Yes, but a UHU servo is probably the better choice. DC servos usually operate at a much lower voltage, and the IGBT module we use is not very efficient at low voltages. ####Does it work with Stepper motors? No. ####Why do you use 2 CPUs? The driver is designed to run of rectified mains, without a transformer. Therefore the high voltage side has to be fully isolated. Here we need to supply about 8 digital I/Os, and measure many analog values. The cheapest way of doing this is to use a second CPU, and only isolate a UART. The communication is running at 5Mbit, but 10Mbit is possible.
