20 GX9 ASD Installation and Operation Manual
I/O and Control
The GX9 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 24 .
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. 21 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). Output lines of the Terminal
Board need not be selected to enable the output. However, output lines will have to be
set to a specific function (see Table 10 on pg. 222 ).
Figure 19 on pg 30 shows the typical connection diagram for the GX9 ASD system.
