Sequencer Commands
A sequencer request is generated from various user inputs to direct the sequencer to
run or flux the drive. A sequencer command is the internal “go ahead” to sequencer
once the permissive logic has been satisfied (see Sequencer Permissives).

The variables Run request and Jog request are associated with Run Commands. They

The variable Full flux request is associated with Flux Commands and directs the
sequencer to flux the drive. If the drive is already fluxed when a run is requested, the
drive will begin running immediately without the delay caused by fluxing the drive.

Run Commands
A run command (initiated either by a Run request or Jog request) will:
•
Enable bridge power
•
Flux the drive (if it is not already fluxed)
•
Enable drive torque
•
Enable the speed regulator
•
Enable the appropriate speed reference

Run

request
select
Selects the variable that drives Run request. This input is only
active in “Remote mode” (Local mode active is False). The
sequencer normally treats the signal as a +/- edge-triggered input to
set Run request. However, if Stop PB select is used, the sequencer
looks only at the + edge of the signal to set Run request. (See
Stopping Commands and Modes for more information on Stop PB
select.)
