1.2.2.4 Customer unit Standard I/O
(SK CU1-STD, Option)
The standard I/O of the customer interface(Customer Unit) provides
sufficient control terminals for most applications and it is fully
terminal-compatible with NORDAC vector mc..
1 analog differential input, 4 digital inputs and 1 analog output are
available for control of the frequency inverter.
Readiness for operation is shown via the 2 relay contacts and a
mechanical motor brake is activated at the correct time.
The connected frequency inverter can be accessed via the RS485
interface. In addition to the entire range of control functions,
parameterisation is also possible.
TheNORD CON software can be used to carry out a simple function
test of the serial interface and the 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.
