Servo Drive and System Comparison Chapter 2
For additional system capacitance and DC-bus current capability, two or three
DC-bus power supplies can be used, but they must be catalog number
2198-P208. For additional output power (kW), you can extend the DC-bus to
another inverter cluster with capacitor modules.
