For power up procedures and system integration with the
ControlLogix and SoftLogix SERCOS modules/PCI cards (see table
below) refer to the 1394 SERCOS interface Integration Manual
(publication 1394-IN024x-EN-P). Manuals are available electronically
(as a .pdf) or in hardcopy from www.theautomationbookstore.com.

Understanding How to
Detect a Problem

When a drive fault occurs, the LED on the front panel changes and a
fault message is transmitted to the position controller.

The majority of 1394 faults cause the Drive System OK contact to
open. If a drive fault occurs, you can reset the fault detection circuitry
by removing and reapplying logic power. However, if it is a hardware
fault, you need to correct the fault before restarting.

This material, along with the diagnostic/troubleshooting information
included with the position controller, will help you identify most
common system malfunctions and determine which module that
problem pertains to.
