Appendix E Regenerative Bus Supply Sequence Operation
Sequence Operation of
Discharging
In the discharging sequence, the regenerative bus supply begins in the
RUNNING state and transitions to the STOPPED state following a Motion
Servo Off (MSF) command. If a Motion Axis Shutdown (MASD) command is
executed, the regenerative bus supply transitions to the SHUTDOWN state,
and a Motion Axis Shutdown Reset (MASR) command must be executed to
transition out of the SHUTDOWN state.
