Default I/O connection diagram
The default connection of the control signals depends on the application macro in
use, which is selected with parameter 9902 APPLIC MACRO.
The default macro is the ABB standard macro. It provides a general purpose I/O
configuration with three constant speeds. Parameter values are the default values
given in section Default parameter values with different macros on page 79. For
information on other macros, see chapter Application macros on page 69.
The default I/O connections for the ABB standard macro are given in the figure
below.
