Parameter Descriptions
6-62 Terminal X30/8 Max. Scale
Range: Function:
100 [0 - Scales the maximum output of the selected
% 200 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 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 x 100%
20 − 4

6-63 Terminal X30/8 Bus Control
Range: Function:
0 % [0 - 100 %] Holds the level of Output X30/8 if controlled
*
by bus.
6-64 Terminal X30/8 Output Timeout Preset
Range: Function:
0 % [0 - 100 Holds the preset level of Output X30/8.
*
%] In case of a bus timeout and a timeout
function is selected in parameter 6-60 Terminal
X30/8 Output, the output is preset to this level.
3.8.8 6-7* Analog Output 3 MCB 113
Parameters for configuring the scaling and limits for
analog output 3, Terminal X45/1 and X45/2. Analog
outputs are current outputs: 0/4–20 mA. Resolution on
analog output is 11 bit.
