Input Power Configurations

Three-phase
These 8720MC regenerative power supply (RPS) examples in common-bus
configurations show DC-bus regenerative power and full-line power.

AC Input and Regenerative Power Configuration

In this configuration the servo drive provides motoring power and the RPS
unit receives regenerative power.
