ABB ACS880-207 Hardware Manual page 135

The table above shows the control connections of the IGBT supply unit, and the default
meaning or use of the signals in the control program. Most I/O connections are reserved
and wired for the internal use at the factory. Do not change the connections.
Wire sizes and tightening torques: 0.5 ... 2.5 mm
both stranded and solid wiring.
Notes:
1)
Switch D2D.TERM. Must be set to ON when the supply unit is the first or last unit on the drive-to-drive (D2D)
link. On intermediate supply units, set termination to OFF.
2)
Use of the signal in the control program. When parameter 120.30 External charge enable has value Yes
(default setting), the control program reserves this I/O terminal for external charging circuit control and
monitoring, and parameters 110.24 RO1 source and 110.30 RO3 source are write-protected. If the value is No,
you can use the I/O terminal for other purposes. See the firmware manual for more details.
3)
Default use of the signal in the control program. The use can be changed by a parameter. For the delivery-
specific use, see the delivery-specific circuit diagrams.
4)
The Safe torque off (STO) function is only implemented in the inverter units. When the control board is used
in the supply or brake unit, de-energizing IN1 or IN2 of XSTO connector only stops the operation of the supply
or brake unit. This stopping is not safety related and can not be used in safety purposes.
5)
Total load capacity of these outputs is 4.8 W (200 mA at 24 V) minus the power taken by DIO1 and DIO2.
6)
Determines whether DICOM is separated from DIOGND (ie, common reference for digital inputs floats).
DICOM=DIOGND ON: DICOM connected to DIOGND. OFF: DICOM and DIOGND separate.
7)
Current [0(4)...20 mA, R
Change of setting requires reboot of control unit.
8)
Current [0(4)...20 mA, R
Change of setting requires reboot of control unit.
