Digital input 2 (DI2) can also be used as input in frequency (FI). For further details refer to the programming manual of the
MW500.

For further information, refer to the detailed specification in
section 8.2 - Electronics/General Data
.
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.1
.
The MW500 drives 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 the termination
resistor of the RS485 OFF.
NOTE!
To use the analog inputs and/or outputs with signal in current, you
must set switch S1 and related parameters as per
table 3.1
. For further
information, refer to the MW500 programming manual.
To modify the digital inputs from active low to active high, check the
use of parameter P0271 in the MW500 programming manual.
