Regenerative Bus Supply Configurations With Active Shunt Chapter 5

In this example, standalone AC drives, Kinetix 6x00 drives, and Kinetix 7000 drives receive DC-bus power from the 2198-RP200 regenerative

bus supply. An external active shunt is connected to the regenerative bus supply active-shunt (RC) connector.

(1) A line reactor can be required. For line reactor selection, see the Kinetix 5700 Servo Drives User Manual, publication 2198-UM002.

(2) Kinetix 5700 regenerative bus supplies require an isolation transformer when connected to corner-grounded or ungrounded facility power.

(3) Due to the 10 A connector current rating, connections to the 2198-RPxxx (RC connector) are limited to only Powerohm PKBxxx active shunts rated at 7 kW or less.

(4) External active shunt module. For active shunt mounting and wiring considerations, see the Kinetix 5700 Servo Drives User Manual, publication 2198-UM002

(5) Kinetix 5700 regenerative bus supplies in mixed common-bus systems require a DC-bus conditioner module in the power supply cluster.
