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 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 H9 ASD system.
