6.2.9 Change Display
Parameter
(An.22 Bit 7)
We have seen in this chapter, the original analog signal can be effected, that the
function is different at the end. With changing the displays you can describe the input
(standard) or the output of the analog signal processing. For this case bit 7 (value
128) must be set in parameter An. 22. (see chapter 6.2.4 at the bottom).
In our example from chapter 6.2.5. with 0...10V the display would show 0...100% at
the input and -100...100% at the output.
6.2.10 Short Description
Analog Output
The KEB COMBIVERT has a programmable analog output (AOUT). Different values
can be selected with parameter An.14 which is then given on output X1.15. ru.41
displays the selected value. With the characteristics amplifier (An.15, An.16, An.17)
the analog signal can be adjusted according to the requirements.
100% ru.41 correspond to An.14 =
0 Actual frequency (102,4 Hz)
1 Actual load (200 %)
2 Setpoint frequency (102,4 Hz)
3 Output voltage (500 V)
4 DC-bus voltage (405 V/810 V)
5 Active current (2*I
rated
)
6 PI-controller manipulated variable (100 %)

A voltage between 0...10V DC corresponds to 0...±100% with a resolution of 9 Bit of
the selected value. 100% correspond to the bracket values in picture 6.2.10
