Parameter Descriptions
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.
3 3 Resolution on analog output is 12 bit.

Function:
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 parameter 6-62 Terminal
X30/8 Max. Scale if the value is below 100%.
This parameter is active when option module MCB
101 is mounted in the frequency converter.
Function:
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 %
20 mA
i . e . 10 mA: × 100 % = 200 %
10 mA
Function:
terminal, when it is configured as bus-
controlled.
Function:
terminal, when it is configured as bus-
controlled timeout and timeout is detected.
