P9 ASD Installation and Operation Manual 21
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 24 .
Table 2 lists the names, functions, and 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 .
Typical Connection Diagram on pg. 26 shows the typical connection diagram for the ASD system.
