Jumpers And Switches - ABB ACS880-17 Hardware Manual

116 Control unit of frame R11
Notes:
1)
Current [0(4)...20 mA, R = 100 ohm] or voltage [ 0(2)...10 V, R
in
setting requires reboot of control unit.
2)
Current [0(4)...20 mA, R = 100 ohm] or voltage [ 0(2)...10 V, R
in
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 tDIO1 and DIO2.
4)
0 = open, 1 = closed
DI4 Ramp times according to
0 Parameters 23.12 and 23.13
1 Parameters 23.14 and 23.15
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 (D2D) link.
7) Determines whether DICOM is separated from DIOGND (ie. common reference for digital inputs floats).
DICOM connected to DIOGND.
Further information on the usage of the connectors and jumpers is given in the sections below.

Jumpers and switches

Jumper/
Switch
J1 Determines whether analog input AI1 is used as a current or
voltage input.
(AI1)
J2 Determines whether analog input AI2 is used as a current or
voltage input.
(AI2)
J3 Drive-to-drive link termination. Must be set to terminated
position when the drive is the last unit on the link.
J6 Common digital input ground selection switch. Determines
whether DICOM is separated from DIOGND (ie, common
reference for digital inputs floats). See the
diagram on page 121.
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 unit 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 unit power up delay
is allowed).
See also the firmware manual, parameter 95.04.
AI1 and AI2 as Pt100, Pt1000, PTC and KTY84 sensor inputs (XAI, XAO)
Three Pt100, Pt1000 or PTC sensors or one KTY84 sensor for motor temperature
measurement can be connected between an analog input and output as shown below.
(Alternatively, you can connect the KTY to FIO-11 analog /I/O extension module or FEN-xx
encoder interface module.) Do not connect both ends of the cable shields directly to
