Q7 ASD Installation and Operation Manual 19
Control Terminal Strip
I/O and Control
The Q7 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 describes the ASD control
methods and supported I/O functions.
The Control Terminal Strip PCB (P/N 48570) supports discrete and analog I/O functions.
The Control Terminal Strip is shown in Figure 6 on pg. 22 . Table 3 and lists the names, the default
settings, and the descriptions of the input and output terminals.
Figure 18 on pg. 26 shows the basic connection diagram for the Q7 system.
