Non-regenerative Common DC-bus Configurations With Passive or Active Shunt Chapter 3
Figure 16 - DC-bus Supply with Multiple AC Drives and External Active Shunt
(1) Line reactors are required when three 2198-P208 DC-bus supplies are configured. For line reactor requirements and selection when one or two 2198-P208 DC-bus supplies are configured,
see the Kinetix 5700 Servo Drives User Manual, publication 2198-UM002
.
(2) A DC-bus conditioner module is required to limit DC-bus voltage overshoot at power-on.
(3) Locate the external active shunt close to the DC-bus conditioner. For active shunt wiring and mounting information, see the Kinetix 5700 Servo Drives User Manual, publication 2198-UM002
.
