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 176. For information on
other macros, see chapter Application macros on page 109.
The default I/O connections for the ABB standard macro are given in the figure below.
