7.1.1 Step-by-step Troubleshooting

Check: LEDs
The option contains two LEDs to indicate the state of the device and the network. During normal operation the MS and at least one NS LED will show a constant
green light.

Table 7.2: NS1 + NS2: Network Status (one per port)
Check: Link Status
The status of the Ethernet link cannot be directly identified by means of the LEDs, if no CIP connection is established.
Use par. EN-10, Link Status to verify presents of the link.
Use par. EN-11, Link Duration to verify that the link is steady present.
The parameter will show the duration of the present link, and preset to 00:00:00:00 if the link is broken.
Check: Cabling
In rare cases of cabling mis-configuration, the option might show the presents of a link, but no communication is running. Exchange the cable in doubt.
Check: IP Address
Verify that the option has a valid IP address (please refer to section: IP Settings) in par. EN-01, IP Address. If the option has identified a duplicate IP Address NS
LEDs will light steady red. If the option is set up for BOOTP or DHCP, verify that a BOOTP or DHCP server is connected in par. EN-04, DHCP Server. If no server is
connected, the parameter will show: 000.000.000.000.

7.1.2 Alarm Word and Warning Word

Alarm word and warning word are shown in the display in Hex format. If there is more than one warning or alarm, a sum of all warnings or alarms will be shown.
Warning word and alarm word are displayed in par. DR-90 to DR-95. For more information on the individual alarms and warnings, please refer to: AF-650 GP/
AF-600 FP Design Guide.
NB!
Please note that the availability of the individual alarms and warnings are dependent on the drive type: AF-600 FP/AF-650 GP series.
Warning and Alarm Messages
There is a clear distinction between alarms and warnings. In the event of an alarm, the frequency converter will enter a fault condition. After the cause for the
alarm has been cleared, the master must acknowledge the alarm message in order to start operation of the frequency converter again. A warning, on the other
hand, may appear when a warning condition arises, then disappear when conditions return to normal without interfering with the process.
