(*) The digital input 2 (DI2) can also be used as input in frequency (FI). For further details refer to the
programming manual of the CFW501.
(**) For further information, refer to the detailed specification in section
Figure 3.4 (b): Signals of the connector of the CFW500-CRS485 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 CFW501 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 switches S1 and S2 and the related parameters as per
For further information, refer to the CFW501 programming manual.
To modify the digital inputs from active low to active high, check the
„
use of parameter P0271 in the CFW501 programming manual.
