The 2198-RPxxx regenerative bus supply (24...140 kW) provides full-line
motoring and regenerative power to and from the Kinetix 5700 drive system.
In addition, you can extend the DC-bus voltage to additional inverter clusters
via accessory modules.

Typical Regenerative Bus Configuration Examples

In this example, the inverter modules are mounted to the right of the
regenerative bus supply. One single-axis (inverter) module and three dual-axis
(inverter) modules support seven axes of motion. Other features include:
• Digital inputs are wired to sensors and the control circuitry at the IOD
connectors.
• The contactor enable relay protects the regenerative bus supply in the
event of shutdown fault conditions.
• The DC-bus conditioner module is required when the combined motor
cable length exceeds 400 m (1312 ft). See

(1) The regenerative bus supply can be left or right of the inverters. Further, we recommend that the highest inverter power ratings
are positioned closest to the regenerative bus supply and in decreasing order leading away from the regenerative bus supply.
