Switches; Additional Information On I/O Connections; Pnp Configuration For Digital Inputs (X2 & X3) - ABB ACQ580-34 Hardware Manual

76 Control unit
2. 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.
3. In scalar control: See Menu - Primary settings - Drive - Constant frequencies or parameter
group 28 Frequency reference chain.
In vector control: See Menu - Primary setting - Drive - Constant speeds or parameter
group 22 Speed reference selection.
4. Connected with jumpers at the factory.
5. Use shielded twisted-pair cables for digital signals.
6. Ground the outer shield of the cables 360 degrees at the cabinet entry.
7.
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.

Switches

Switch Description
TERM EFB link termination. Must be set
S4 to the terminated (ON) position
when the drive (or another device)
is the first or last unit on the link.
BIAS Switches on the biasing voltages
S5 to the bus. One (and only one)
device, preferably at the end of the
bus must have the bias on.
