22 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 c ontrol methods and
supported I/O functions.
The Control Terminal Strip PCB (P/N 4857 0) s upports discr ete and ana log I/O func tio ns and is s hown
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 ⇒ Fundamental
Parameters ⇒ Standard Mode Selection ⇒ Command Mode ⇒ Use Control
Terminal Strip).
Figure 18 on pg. 30 shows the basic connection diagram for the G7 system.
