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
on page 206 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
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 inTable 10-1
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
).
on page 203 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.
LED State
Description
Off
Ethernet connection not detected.
Steady green
Ethernet connection detected but no data.
Flashing green
Ethernet communication detected and data flow.
