ABB ACS880-1607LC - Default I;O Diagram of the Converter Control Unit (UCU-22

DescriptionTerminal

1)
Must be set to ON when the unit is the first or last unit on the drive-to-drive (D2D) link. On intermediate units, set
termination to OFF.
2)
Default use of the signal in the control program. The use can be changed by a parameter. See also the delivery-specific
circuit diagrams.
3)
This input only acts as a true Safe torque off input in inverter units. In other applications (eg, supply, DC/DC
converter, or brake unit), de-energizing the IN1 and/or IN2 terminal will stop the unit but not constitute a true safety
function.
4)
Total load capacity of these outputs is 4.8 W (200 mA at 24 V) minus the power taken by DIO1 and DIO2.
5)
Determines whether DICOM is separated from DIOGND (ie, common reference for digital inputs floats). ON: DICOM
connected to DIOGND. OFF: DICOM and DIOGND separate.

Default I/O diagram of the converter control unit
(UCU-22…24)
The diagram below shows the default I/O connections of the UCU control unit of the
converter, and describes the use of the connections. Under normal circumstances,
the factory-made wiring should not be changed.
The wire size accepted by all screw terminals (for both stranded and solid wire) is
0.5 … 2.5 mm
2
(22…12 AWG). The tightening torque is 0.45 N·m (4 lbf·in).
