Digital input impedance 1.5 kohm. Maximum voltage for digital
inputs is 30 V.
2
Default values depend on the macro used. Values specified are for
the default macro. See chapter Application macros and wiring .
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.
10 +24V Auxiliary voltage output 24 V DC / 250 mA (reference to
GND). Short circuit protected.
11 GND Auxiliary voltage output common (connected internally as
floating).
12 DCOM 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.
13 DI1 Digital input 1, programmable. Default
2
= start/stop.
14 DI2 Digital input 2, programmable. Default
