G7 ASD 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 Control Terminal Strip PCB (P/N 48570) supports discrete and analog I/O functions and is shown
in
Figure 6 on pg. 25
.
Table 3
lists the names, the default settings, and the descriptions of the input and
output terminals of the Control Terminal Strip PCB.
Note:
To use the input control lines of the Control Terminal Strip the Command Mode
setting must be set to Use Control Terminal Strip (Program
