Default values depend on the macro used. Values specified are for
the default macro. See chapter
Note: Terminals 3, 6, and 9 are at the same potential.
Note: For safety reasons the fault relay signals a "fault" when
the ACH550 is powered down.

Hardware description
Auxiliary voltage output 24 V DC / 250 mA (reference to
GND). Short circuit protected.
Auxiliary voltage output common (connected internally as
floating).
Digital input common. To activate a digital input, there
must be ≥+10 V (or ≤-10 V) between the input and
DCOM. The 24 V may be provided by the ACH550
(X1:10) or by an external 12...24 V source of either
polarity.
Digital input 1, programmable. Default
Digital input 2, programmable. Default
Digital input 3, programmable. Default
speed 1 (parameter 1202).
Digital input 4, programmable. Default
(parameter 1608).
Digital input 5, programmable. Default
Digital input 6, programmable. Default
Relay output 1, programmable
