Viewing the 700S Diagnostic
LEDs
The PowerFlex 700S contains a Run LED, controller LEDs, and SynchLink
LEDs. These LEDs are only operational when the drive is energized and are
only visible when the drive door is open. The status of these LEDs can also
be viewed from the HIM or from an application program (e.g.,
DriveExplorer™) in parameter 554 [LED Status]. This feature is only
available with DriveLogix version 15.03 or later.
