10 Diagnostics
This section of the manual provides basic diagnostic information intended to enable
resolution of the most common problems encountered when setting up the Ethernet
interface on an Ethernet network.
A high percentage of problems reported are basic setup problems that can be avoided
by using the following pages. Start by using the Diagnostic flow chart on page 188 to
determine the possible cause of a problem. If after following the flow chart you are still
experiencing problems please contact your supplier or local drive supplier for support.
10.1 LED diagnostics
Each Ethernet connection has an associated LED to aid diagnostics, in the case of the
onboard Ethernet interface, this LED is mounted below the associated RJ45 connector;
the SI-Ethernet option module has two LEDs mounted on the topside of the module
(Figure 2-1 SI-Ethernet on page 8).
The connection status for the first port (nearest the grounding tab) is indicated by LED
“A”, and the second port is indicated by LED “B”.
The function of these LEDs are described in table 10.1 LED functionality below.
Table 10.1 LED functionality
10.2 Drive trip display codes
If the Ethernet interface detects an error during operation, it will force a trip on the
drive. However, the trip string displayed on the drive will only indicate which slot
initiated the trip, if the error originated from the onboard Ethernet interface then the
default slot will be 4, however, if the SI-Ethernet option module generated the trip then
the slot number will be the slot number the SI-Ethernet option module is fitted to. The
exact reason for the trip will be indicated in the drive trip code parameters (Pr 0.10.020
and Pr 0.10.070).
Table 10.2 Drive trip indications on page 184 following shows the possible trips that will
be displayed on the drive when a problem is detected or the Ethernet interface initiates
a trip.
Please note that support will be limited to the setting up and networking of the drive and
not network infrastructure design.
NOTE
LED State Description
Off Ethernet connection not detected.
Steady green Ethernet connection detected but no data.
Flashing green Ethernet communication detected and data flow.
