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. The
typical functions and connections for the CFW500-IOS standard plug-in module are shown in
Figure 3.4 on page 23. For further details about the specifications of the connector signals,
refer to Chapter 8 TECHNICAL SPECIFICATIONS on page 44.

(*) 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.

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 Figure A.2 on page 153.
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 Table 3.2 on page 24.
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.
