H9 ASD Installation and Operation Manual 21
I/O and Control
The H9 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 H9 ASD control methods
and supported I/O functions.
The Terminal Board supports discrete and analog I/O functions and is shown in Figure 9 on pg. 24. Table
2 lists the names, functions, and the settings (default settings of programmable terminals) of the input and
output terminals of the Terminal Board.
Note: To use the input lines of the Terminal Board to provide Run commands the Command
Mode setting must be set to Terminal Block.
Figure 20 on pg. 26 shows the typical connection diagram for the H9 ASD system.
