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.
