ABB ACQ580-34 User Manual

Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [0(2)…10 V, R
in
>200 kohm]. Change of setting requires
changing the corresponding parameter.
1)
Total load capacity of the Auxiliary voltage output +24V (X2:10) is 6.0 W (250 mA / 24 V) minus the power
taken by the option modules installed on the board.
2)
In scalar control: See Menu > Primary settings > Start, stop, reference > Constant speeds / constant
frequencies or parameter group 28 Frequency reference chain.
3)
In vector control: See Menu > Primary settings > Start, stop, reference > Constant speeds / constant
frequencies or parameter group 22 Speed reference selection.
Connected with jumpers at the factory.4)
Use shielded twisted-pair cables for digital signals.5)
Ground the outer shield of the cables 360 degrees at the cabinet entry.6)
WARNING! Connect external AC power supply (24 V AC) to control unit connectors 40 and 41.
If you connect it to connector AGND, DGND or SGND, the power supply or the control unit can
get damaged.
