Installation and Connection

3.2.5 Control Connections

The control connections (analog input/output, digital input/output and interface RS485)
must be performed according to the specification of the connector of the plug-in module
connected to the CFW500. Refer to the guide of the plug-in module in the package of the
product or in the CD manual of the product. The typical functions and connections for the
CFW500-IOS standard plug-in module are shown in
the specifications of the connector signals, refer to
The digital input 2 (DI2) can also be used as input in frequency (FI). For further details refer to the programming manual of
(*)
the CFW500.
For further information, refer to the detailed specification in

Figure 3.4: Signals of the connector of the CFW500-IOS plug-in module
The location of the plug-in module and DIP-switches to select the type of analog input
and output signal and the termination of the RS485 network is shown in
The CFW500 inverters are supplied with the digital inputs configured as active low (NPN),
analog input and output configured for signal in voltage 0...10 V and with termination
resistor of the RS485 OFF.
NOTE!
To use the analog inputs and/or outputs with signal in current, you
„
must set the switch S1 and the related parameters as per
For further information, refer to the CFW500 programming manual.
To modify the digital inputs from active low to active high, check the
„
use of parameter P0271 in the CFW500 programming manual.
