6.1 Step-by-step Troubleshooting

6.1.1 LED Status
The EtherNet/IP interface has 3 bicolored LEDs that allow
fast and detailed diagnosis. Each LED is linked to its unique
part of the EtherNet/IP interface, see Table 6.1.

6.1.2 No Communication with the
Frequency Converter
Check: Link status
If CIP connection is not established, the status of the
Ethernet link cannot be directly identified using the LEDs.
Verify presence of the link via parameter 12-10 Link Status.
Verify that the link is constantly present via
parameter 12-11 Link Duration.
The parameter shows the duration of the present link and
is preset to 00:00:00:00 when the link is broken.

Solid red The device has detected an unrecoverable fault
(MAU).

Flashing green There are no established CIP connections to the
device.
Solid green There is at least 1 established CIP connection to
the device.
Flashing red 1 or more CIP connections have timed out.

green
Check: Cabling
In rare cases of cabling misconfiguration, the option may
show the presence of a link, but no communication is
running. Exchange the cable if in doubt.
Check: IP address
Verify that the option has a valid IP address (refer to
parameter 12-01 IP Address). When the option has identified
a duplicate IP address, NS LEDs are solid red. When the
option is set up for BOOTP or DHCP, verify that a BOOTP or
DHCP server is connected in parameter 12-04 DHCP Server.
If no server is connected, the parameter shows:
000.000.000.000.
