I/O and Control
The W7 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 PCBA (P/N 48570) supports discrete and analog I/O functions.
The Control Terminal Strip is shown in Figure 5 on pg. 20. Table 2 and lists the names, the default settings (where applicable), and the descriptions of the input and output terminals.
Figure 17 on pg. 24 shows the basic connection diagram for the W7 ASD system.
