Connecting the control cables
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 (see page 32).
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 chapter Actual signals and parameters in ACS310 Users Manual
(3AUA0000044201 [English]). For other macros, see I/O connections in chapter
Application macros in the same manual, and default values on page 28 in this
manual.
The default I/O connections for the ABB standard macro are given in the figure below.
