3.8.7 6-6* Analog Output 2 MCB 101
Analog outputs are current outputs: 0/4–20 mA. Common
terminal (terminal X30/8) is the same terminal and
electrical potential for analog common connection.
Resolution on analog output is 12 bit.
6-60 Terminal X30/8 Output

6-61 Terminal X30/8 Min. Scale
Range:
Function:
0 %
*
[0 -
200 %]
Scales the minimum output of the selected analog
signal on terminal X30/8. Scale the minimum value
as a percentage of the maximum signal value, that
is 0 mA (or 0 Hz) is desired at 25% of the
maximum output value and 25% is programmed.
The value can never be higher than the
corresponding setting in
if the value is below 100%.
This parameter is active when option module MCB
101 is mounted in the frequency converter.
6-62 Terminal X30/8 Max. Scale
Range:
Function:
100
%
*
[0 -
200
%]
Scales the maximum output of the selected
analog signal on terminal X30/8. Scale the value
to the desired maximum value of the current
signal output. Scale the output to give a lower
current than 20 mA at full scale, or 20 mA at an
output below 100% of the maximum signal value.
If 20 mA is the desired output current at a value
between 0–100% of the full-scale output,
programme the percentage value in the
parameter, that is 50%=20 mA. If a current
between 4 and 20 mA is desired at maximum
output (100%), calculate the percentage value as
follows:
20 mA/desired maximum current × 100 %
i . e . 10 mA:
20 mA
10 mA × 100 % = 200 %
6-63 Terminal X30/8 Output Bus Control
Range:
Function:
0 %
*
[0 - 100 %] Contains the value to apply to the output
terminal, when it is configured as bus-
controlled.
6-64 Terminal X30/8 Output Timeout Preset
Range:
Function:
0 %
*
[0 - 100 %] Contains the value to apply to the output
terminal, when it is configured as bus-
controlled timeout and timeout is detected.
