6-53 Terminal 42 Output Bus Control
Range: Function:
0 % [0 - 100 %] Holds the level of Output 42 if controlled by
*
bus.
6-54 Terminal 42 Output Timeout Preset
Range: Function:
0 % [0 - 100 %] Holds the preset level of Output 42.
*
In case of a bus timeout and a timeout
function is selected in 6-50 Terminal 42
Output the output will preset to this level.
3.8.8 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
Same options and functions as 6-50 Terminal 42 Output.
Option:
[0] No operation
*
6-61 Terminal X30/8 Min. Scale
Range: Function:
0 % [0 - Scales the minimum output of the selected
*
200 %] analog signal on terminal X30/8. Scale the
minimum value as a percentage of the maximum
signal value, i.e. 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 6-62 Terminal X30/8
Max. Scale if value is below 100%.
This parameter is active when option module
MCB 101 is mounted in the frequency converter.

Function:
[0 - Scales the maximum output of the selected analog
200 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
ful-scale output, program the percentage value in
the parameter, i.e. 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:
[0 - 100 %] Contains the value to apply to the output
