Appendix E Regenerative Bus Supply Sequence Operation
Converter Startup Method -
Enable Request
When the Enable Request method is selected, a Motion Servo On (MSO)
commend is required for the regenerative bus supply to transition from the
STOPPED state to the RUNNING state.

Initialization
The 2198-RPxxx regenerative bus supply uses the
AB:MotionDevice_Diagnostics:S:0 tag data type.
Initialization consists of these four events:
• A connection is established between the controller and regenerative bus
supply, through a forward open request from the controller
• The regenerative bus supply receives the configuration from the
controller
• The Group Sync Service synchronizes with the regenerative bus supply
• The configuration and power are verified for the axes and associated
modules in the Motion Group.
Following initialization, the regenerative bus supply transitions to the
PRECHARGE state.
