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 values with different macros on page 165 . For information on
other macros, see chapter Application macros on page 101 .
The default I/O connections for the ABB standard macro are given in the figure below.
