Kinetix 7000 Drive System Design Guide
Kinetix 7000 AC Input Power Example (with regenerative power)
In this example, the Kinetix 7000 drive system is shown with the 8720MC Regenerative Power Supply (RPS) in DC common-bus configuration
with two follower Kinetix 7000 drives. Harmonic filter and varistor are available separately, but are included with the RPS unit when ordering
catalog number 8720MC-RPS065-BM-HV2.
In this full-line regenerative example, the 8720MC-RPS065 unit provides motoring power and regenerative braking.
IMPORTANT
Regenerative braking applications are limited to only one Kinetix 7000 common-bus follower drive.
