G9 ASD Quick Start Guide 17
I/O and Control
The 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 9 on pg. 20.
Table 2 lists the names, descriptions, and 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. 22 shows the basic connection diagram for the G9 ASD system.
