ABB ACS880-34 - External Power Supply for the Control Unit

External control unit 109
Notes:
1) Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [0(2)…10 V, R
in
> 200 kohm] input selected by jumper J1.
Change of setting requires reboot of control unit.
2) Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [0(2)…10 V, R
in
> 200 kohm] input selected by jumper J2.
Change of setting requires reboot of control unit.
3) Total load capacity of these outputs is 4.8 W (200 mA / 24 V) minus the power taken by DIO1 and DIO2.
4) 0 = Acceleration/deceleration ramps defined by parameters 23.12/23.13 in use.
1 = Acceleration/deceleration ramps defined by parameters 23.14/23.15 in use.
5) Constant speed 1 is defined by parameter 22.26.
6) Must be set to ON when the drive is the last unit on the drive-to-drive (XD2D) link.
7) Determines whether DICOM is separated from DIOGND (ie. common reference for digital inputs floats).
See also Ground isolation diagram on page 117.
DICOM connected to DIOGND. DICOM and DIOGND separate.
8) See section DIIL input (XD24:1) on page 111.
External power supply for the control unit
External +24 V (2 A) power supply for the control unit can be connected to terminal block
XPOW. Using an external supply is recommended if
• the control board needs to be kept operational during input power breaks, for example,
due to uninterrupted fieldbus communication
• immediate restart is needed after power breaks (that is, no control board power up
delay is allowed).
