Electrical installation – IEC 145
IEC
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 24V (X2:10) is 6.0 W (250 mA / 24 V).
3)
In scalar control: See Menu > Primary settings > Start, stop, reference > Constant
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.
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.
