20 WX9 ASD Installation and Operation Manual
I/O and Control
The WX9 ASD can be controlled by several input types and combinations thereof, as well as operate
within a wide range of output frequency and voltage levels. This section discusses the ASD control
methods and supported I/O functions.
The
Terminal Board supports discrete and analog I/O functions and is shown in Figure 6. on pg. 21 .
Table 2 lists the names and the default settings of the input and output terminals of the Terminal
Board . See the section titled Terminal Descriptions on pg. 22 for an expanded description of each
terminal.
Note: Set the Command Mode to Terminal Board to use the input control lines of the
Terminal Board for command input (Program

Terminal Board need not be selected to enable the output. However, output lines may
be set to a user-selected function.
Figure 20 on pg. 30 shows the typical connection diagram for the WX9 ASD system.
