Parameter Descriptions
6-73 Terminal X45/1 Output Bus Control
Range: Function:
0.00% [0.00 - 100.00%] Holds the level of analog output 3
*
(terminal X45/1) if controlled by bus.
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).
If there is a fieldbus timeout and a
timeout function is selected in
parameter 6-70 Terminal X45/1 Output, the
output is 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, terminals X45/3 and X45/4. Analog outputs are
current outputs: 0/4 to 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.
[0] No operation Same selections available as for
*
parameter 6-70 Terminal X45/1 Output.
6-81 Terminal X45/3 Output Min. Scale
Option: Function:
[0.00%] 0.00 - Scales the minimum output of the
*
200.00% selected analog signal on terminal X45/3.
Scale the minimum value as a percentage
of the maximum signal value, for example,
0 mA (or 0 Hz) is required at 25% of the
maximum output value and 25% is
programmed. The value can never exceed
the corresponding setting in
parameter 6-82 Terminal X45/3 Max. Scale if
value is below 100%.
This parameter is active when VLT
Extended Relay Card 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 required 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
required output current at a value between
0–100% of the full-scale output, program
the percentage value in the parameter, for
example, 50%=20 mA. If a current of 4–20

Option:
[0.00%]
6-84 Terminal X45/3 Output Timeout Preset
Option:
[0.00%]

Function:
mA is required at maximum output (100%),
calculate the percentage value as follows
(example where required maximum output
is 10 mA):
I mA
RANGE
x 100 %
I mA
DESIRED MAX
20 − 4 mA
= x 100 % = 160 %
10 mA
Function:
0.00 - 100.00% Holds the level of output 4 (X45/3) if
*
controlled by bus.
Function:
0.00 - Holds the present level of output 4
*
100.00% (X45/3). If there is a fieldbus timeout and
a timeout function is selected in
parameter 6-80 Terminal X45/3 Output, the
output is preset to this level.
