Electrical installation 119
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 +24V (X2:10) is 6.0 W (250 mA / 24 V)
minus the power taken by the option modules installed on the board.
3)
AI1 is used as a speed reference if vector control is selected.
4)
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.
5)
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.
6)
Connected with jumpers at the factory.
7)
Use shielded twisted-pair cables for digital signals.
8)
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 on page 186.
