6-53 Terminal 42 Output Bus Control
Range: Function:
0.00 %* [0.00 - 100.00 %] Holds the level of Output 42 if
controlled by bus.
6-54 Terminal 42 Output Timeout Preset
Range: Function:
0.00 %* [0.00 -
100.00 %]
Holds the preset level of Output 42.
6-54 Terminal 42 Output Timeout Preset
Range: Function:
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.
3.8.7 6-6* Analog Output 2 MCB 101
Analog outputs are current outputs: 0/4 - 20mA. 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: Function:
[0] * No operation
6-61 Terminal X30/8 Min. Scale
Range: Function:
0.00
%*
[0.00 -
200.00 %]
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, i.e. 0mA (or 0hz) 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.

%]
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 20mA at full scale or 20mA at an
output below 100% of the maximum signal
value. If 20mA 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% = 20mA. If a current
between 4 and 20mA is desired at maximum
output (100%), calculate the percentage value
as follows:
