DC-bus Power Supply Behavior

Stopping action for exception fault codes does not apply to the DC-bus power
supply. The StopDrive exception action for a DC-bus power 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 Stop Drive, except
the power supply enters into Shutdown as the final state and requires a
Shutdown Reset to recover.
