Q9 Plus ASD Installation and Operation Manual
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. 23
.
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. 25
shows the typical connection diagram for the
Q9 Plus ASD
system.
