Revision Information

This supplement is dedicated to Revision 2.6 and Revision 2.7 of the DCS800 Firmware.

Drives shipped after March, 2008 will most likely have this revision.

To determine your firmware revision number, check the value of signal:

FirmwareVer (4.01).

Or check the label on the box:

Indicates Revision 2.6

1. New Macros: Four new macros have been added. See details later in this

supplement.

2. Date display in control panel data logger: The data logger now correctly displays the

date and time of the fault.

3. Autotuning field current controller assistant: Autotuning now works when both field

exciters are enabled.

4. Nuisance A131 ParAdded: This alarm was seen sometimes after drive is energized.

This has now been corrected.

5. RdyOn with RDIO: When energizing the drive and using a RDIO, the signal RdyOn

(MainStatWord 8.01) came on too early.
