3.4.3.3 Signal status LEDs
The statuses shown by the LED can be read out with the aid of a parameterisation tool from Getriebebau
NORD (NORD CON software, SimpleBox, ParameterBox) and of course via the information parameter
(P173) "Module Status" (Section 6.3.2).
Displays specific to the module
The status of the Technology Unit or the system bus is indicated by the LEDs DS and DE.
LED (green)
DS
 Device State
LED (red)
DE
 Device Error
Meaning
... slow flashing = 2Hz (0.5s cycle)
… quick flashing = 4Hz (0.25s cycle)
OFF OFF Technology Unit not ready, no control voltage
ON OFF Technology Unit ready, no error, at least one frequency inverter is
communicating via the system bus
ON Flashing 0.25s Technology Unit ready, however
one or more of the connected frequency inverters
is in error status
Flashing 0.25s OFF Technology Unit ready and at least one further participant is connected
to the system bus, however,
 there is no frequency inverter on the system bus (or the connection
is interrupted)
 Address error of one or more system bus participants
Flashing 0.25s Flashing 0.25s
Flashing interval
1 x - 1s pause
System bus is in "Bus Warning" status
 Communication on the system bus faulty or
 no other participant on the system bus
Flashing 0.25s Flashing 0.25s
Flashing interval
2 x - 1s pause
 System bus is in "Bus Off" status or
 the 24V voltage supply to the system bus
has been interrupted during operation
Flashing 0.25s Flashing 0.25s
Flashing interval
3 x - 1s pause
 no 24V voltage supply to the system bus
(System bus is in "Bus Off" status)
Flashing 0.25s Flashing 0.25s
Flashing interval
4 x - 1s pause
Module fault
 EEPROM fault
Flashing 0.25s Flashing 0.25s
Flashing interval
5 x - 1s pause
Module fault
 AOUT error (analog output)
 DIP switch configuration error
OFF Flashing 0.25s
Flashing interval
1…7 - 1s pause
System error, internal program execution fault
 EMC interference (observe wiring guidelines!)
 Module faulty
