Chapter 3 Non-regenerative Common DC-bus Configurations With Passive or Active Shunt
Kinetix 5700 Non-Regenerative Bus Supply Considerations
When extending the DC-bus from the power supply cluster, a capacitor module must be used to extend the bus. Refer to Kinetix 5700
Accessory Modules on page 71 for more information on when accessory modules are required.
The 2198-Pxxx DC-bus power supplies do not have a digital output, however, the CIPAxisState tag can be used either programmatically or
with an external digital output to indicate that the drives can pull power from the bus. Refer to Integrated Motion on the EtherNet/IP Network
Reference Manual, publication MOTION-RM003
, and Knowledgebase Answer ID: QA35126, for more information on programming with
Integrated Motion drives
Shunt Connections
The 2198-Pxxx DC-bus power supplies all include an internal shunt that is wired to the shunt resistor (RC) connector at the factory. Bulletin
2198-Rxxx external passive shunts are available to provide additional shunt capacity for applications where the internal shunt capacity is
exceeded.
Connect an external passive shunt to only the DC-bus power supply. You must disconnect the internal shunt wires at the RC connector before
connecting external passive-shunt resistor wires.
Catalog numbers 2198-R014, 2198-R031, and 2198-R127 are composed of resistor coils that are housed inside an enclosure. Catalog number
2198-R004 is a shunt resistor without an enclosure.

Refer to the Kinetix 5700 Servo Drives User Manual, publication 2198-UM002, for passive shunt wiring and mounting considerations.
