Chapter 7 Troubleshoot the Kinetix 5700 Drive System
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.
Fault actions are shown in Table 141
and Table 142.
