82 Control unit
Notes:
1. Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [0(2)…10 V, R
in
> 200 kohm] input selected with switch
AI1. Change of setting requires changing the corresponding parameter.
2. Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [ 0(2)…10 V, R
in
> 200 kohm] input selected with switch
AI2. Change of setting requires changing the corresponding parameter.
3. Current [0(4)…20 mA, R
in
= 100 ohm] or voltage [ 0(2)…10 V, R
in
> 200 kohm] output selected with switch
AO1. Change of setting requires changing the corresponding parameter.
4. 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 control unit.
5. AI1 is used as a speed reference if vector control is selected.
6. In scalar control (default)
: See Menu - Primary settings - Start, stop, reference - Constant frequencies
or parameter group 28 Frequency reference chain.
In vector control
: See Menu - Primary setting - Start, stop, reference - Constant speeds or parameter
group 22 Speed reference selection.
7. In scalar control (default)
: See Menu - Primary settings - Ramps or parameter group 28 Frequency
reference chain.
In vector control
: See Menu - Primary settings - Ramps or parameter group 23 Speed reference ramp.
8. Connected with jumpers at the factory unless with options +L537 and +Q951.
9. Note: Use shielded twisted-pair cables for digital signals.
10. 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.
