3.2.6 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 MW500. Refer to the guide of the plug-in module in print. The typical functions and
connections for the CFW500-IOS standard plug-in module are shown in
19. For further details about the specifications of the connector signals, refer to
TECHNICAL SPECIFICATIONS on page
(*) 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
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.3 on page 200
The MW500 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 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
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, available for download
on WEG website: www.weg.net.
