3.4 Connection of multiple device to a parameterisation tool
In principle it is possible to access several frequency inverters via the
ParameterBox
or the
NORD CON software
. In the following example, communication is made via the parameterisation tool,
by tunnelling the protocols of the individual devices (max. 8) via the common system bus (CAN). The
following points must be noted:
1. Physical bus structure
Establish a CAN connection (system bus) between the devices (Terminal: X9 or X10 (Type: RJ
45))
2. Supply electricity (24 V) to the CAN bus. Establish the connection, for example via the RJ45 –
WAGO connection module (please see chapter 2.11 "RJ45 WAGO- Connection module")
3. Parameterisation

To adopt the addresses, the 24 V supply of the CAN bus must be completely switched off
for approx. 30 sec.
4. Connect the parameterisation tool as usual via RS485 (Terminal: X11 (Type: RJ12)) to the
first
frequency inverter.
Conditions / Restrictions:
a. In order to use the complete range of functions the
first
frequency inverter (
FI 1
) must at least
correspond to the firmware status 2.2 R0 (SK 54xE) or 3.0 R0 (all other SK 5xxE devices).
b. All other connected frequency inverters from the series must at least have a firmware status of
2.1 R0, in order to display the devices 5 … 8 correctly. Devices with a firmware version which is
older than 1.8 R0 do not have the required functionality.
c. If NORDCON is connected to an inverter other than
FI 1
, the status of
FI 1
will be displayed as
"Not ready". The status of devices 5 – 8 will also be displayed as "Not ready" if they have a
software status which is older than 2.1 R0.
d. The parameterisation tools must also correspond to the latest software status:
NORDCON
≥ 02.03.00.21
ParameterBox
≥ 4.5
R3.
