ABB ACH580-01 - Switches

Notes:
1)
Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [ 0(2)…10 V, R
in
> 200 kohm]. Change
of setting requires changing the corresponding parameter.
2)
Total load capacity of the Auxiliary voltage output +24 V (X2:10) is 6.0 W (250 mA /
24 V).
3)
In scalar control: See Menu > Primary settings > Start,stop, reference > Constants
speeds / constant frequencies or parameter group 28 Frequency reference chain.
In vector control: See Menu > Primary setting > Start, stop, reference > Constant
speeds / constant frequencies or parameter group 22 Speed reference selection.

: See Menu > Primary settings > Ramps or parameter group 23 Speed reference
ramp.
4)
Connected with jumpers at the factory.
5)
Use shielded twisted-pair cables for digital signals.
6)
Ground the outer shield of the cable 360 degrees under the grounding clamp on the
grounding shelf for the control cables.
Further information on the usage of the connectors and switches is given in the sections
below. See also section Control connection data (page 291).
Switches
PositionDescriptionSwitch
Bus not terminated (de-
fault)
TERM
ON
EFB link termination. Must be set to the termin-
ated (ON) position when the drive is the first or
last unit on the link.
S4
(TERM)
Bus terminated
TERM
ON
Bias off (default)
BIAS
ON
Activates on the biasing voltages to the bus.
One (and only one) device, preferably at the
end of the bus must have the bias on.
S5
(BIAS)
Bias on
