1.2.3 SK 300E
Technology units and customer interfaces
Through the combination of modules for the
display, (technology units) and modules with
digital and analog inputs, as well as interfaces,
(customer units) or bus interfaces, the SK 300E
can be easily adapted to the requirements of a
wide range of applications.
The NORD CON software can be used to carry
out a simple function test of the serial interface
and parameterisation of the inverter. For this, an
interface converter (e.g. SK IC1-232/485) must
be used between the PC and the inverter.
Following successful parameterisation, the
complete data set can be stored as a file by
means of NORD CON.
Further details can be found in Manual BU 0300.
USS interface (RS485)
With the SK 300E, an RS485 interface is lead out to a 4-pin M12
round connector (Detail 1) as standard. In addition to being used
for external control (ParameterBox) it can also be used as a bus
interface.
If required an M12 SUB D9 (Part No.. 278910060) connecting
cable is available.
Parallel to the external M12 connection, in the connection unit
(trio interface, removed from FI) terminals 73/74 are also
available for connection.
The RS485 termination resistor (Detail 2) can be switched in or
out using the DIP switch in the connection unit.
