Wiring ASDA-B3 Connecting multiple servo drives (in series) Using a common DC Bus can increase the efficiency of the regenerative energy. 3 For instance, while one of the axes is decelerating, the regenerative energy can supply other axes. If you need to connect servo drives of different power levels, only models of similar power levels can be connected. Example (a servo system only allows servo drives of two different power levels) 1. If there is a 400 W servo drive in the system, you can connect a 200 W servo drive, and the regenerative resistor (or braking unit) should connect to the 400 W servo drive. 2.
If there is a 400 W servo drive in the system, you can connect a 750 W servo drive, and the regenerative resistor (or braking unit) should connect to the 750 W servo drive.
