7.1.2 Display Mode
The CAN-ID, warnings and error codes can be displayed on
the 7-segment display.
A dot at the bottom right of the display segment shows
the respective type of indicator. The sequence of the
display occurs as demonstrated in the graphic below.
Continually pressing the <SET> push button enables
scrolling through the display.

CAN-ID
(no segment
dot) Encoder box CAN-ID

Display: decimal.
•
Factory setting: 100.
See chapter 6.2.3 CAN Settings for information
on how to change the CAN-ID.
WARN
(segment dot
“Warn”) Warning about a potential error, e.g. incorrect
CAN-ID.
•
Display: 4-digit hexadecimal code
See chapter 12.3 Emergency Codes for a
description of the emergency codes.
ERROR
(segment dot
“Err”) An error occurred, e.g. encoder CRC error.
•
Display: 4-digit hexadecimal code
See chapter 12.3 Emergency Codes for a

7.1.3 7-Segment Display
During operation the 7-segment display shows the current
encoder box CAN-ID. The LED "Run/Err" is constantly lit
green.
The last 6 warnings and error messages can be called up
on the 7-segment display. Press the <SET> push button
repeatedly to scroll through the individual lists. These are
displayed as a continual loop (see
Illustration 7.2 ):

Press the <SET> push button for 3 seconds to jump to the
start (CAN-ID).
When a new event occurs, it is displayed as follows:
•
The error code is shown on the 7-segment
display immediately. The type of event is shown
via the "Warn" or "Err" segment dot.
•
The LED "Run/Err" is constantly lit red.
•
The error message (CAN emergency message)
appears on the CAN bus.
•
The cause of the error and the date and time
stamp are saved in the log file.
•
An entry is made in the error memory. This can
be read via SDO (Service Data Object).
Depending on the error, the encoder box switches to a
different NMT-state. For example, the encoder box
switches to "pre-operational" if an encoder error occurs.
The full list of error codes and NMT reactions are detailed
in chapter
12.3 Emergency Codes .
NOTE
It is not possible to reset errors or warnings on the
encoder box itself. An active error can only be deleted by
carrying out an NMT-Reset or by restarting the encoder
box. See chapter
12.3 Emergency Codes for further
information.
