Parameter Descriptions
6-74 Terminal X45/1 Output Timeout Preset
Range: Function:
0.00% [0.00 - Holds the preset level of Analog Output 3
*
100.00%] (terminal X45/1).
In case of a bus timeout and a timeout
function is selected in par. 6-70 Terminal
X45/1 Output the output will preset to this
level.
3.8.9 6-8* Analog Output 4 MCB 113
Parameters for configuring the scaling and limits for analog
output 4. Terminal X45/3 and X45/4. Analog outputs are
current outputs: 0/4 – 20 mA. Resolution on analog output is
11 bit.
6-80 Terminal X45/3 Output
Option: Function:
Select the function of Terminal X45/3 as an
analog current output.

6-81 Terminal X45/3 Output Min Scale
Option: Function:
[0.00%] 0.00 - Scales the minimum output of the selected
*
200.00% analog signal on terminal X45/3. 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 par. 6-82 Terminal X45/3 Max.
Scale if value is below 100%.
This parameter is active when option
module MCB 113 is mounted in the
frequency converter.
6-82 Terminal X45/3 Output Max Scale
Option: Function:
[0.00%] 0.00 - Scales the maximum output of the selected
200.00% analog signal on terminal X45/3. 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 (example where desired max. output
is 10 mA):
