Regenerative Bus Supply Behavior

Stopping action for exception fault codes does not apply to the regenerative bus
supply. The Disable exception action for a regenerative bus supply means the
power supply enters into a Major Fault state that opens the contactor-enable
output, removing three-phase power from the Kinetix 5700 drive system. The
Shutdown exception action exhibits the same behavior as Disable, except the
power supply enters into Shutdown as the final state and requires a Shutdown
Reset to recover.
