Connection examples of two-wire and three-wire sensors
Hand/Auto, PID control, and Torque control macros (see section Application macros ,
pages 114 , 115 and 116 , respectively) use analog input 2 (AI2). The macro wiring
diagrams on these pages use an externally powered sensor (connections not shown).
The figures below give examples of connections using a two-wire or three-wire
sensor/transmitter supplied by the drive auxiliary voltage output.
Note: Maximum capability of the auxiliary 24 V (200 mA) output must not be
exceeded.
Note: The sensor is supplied through its current output and the drive feeds the supply
voltage (+24 V). Thus the output signal must be 4…20 mA, not 0…20 mA.

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 180 . For information on
other macros, see chapter Application macros on page 107 .
