Enable the function of outputting the DC-
link voltage on analog outputs. It scales the
output according to the maximum and
minimum voltage of the current drive size.
6-51 Terminal 42 Output Min Scale
Range:
Function:
0 %
*
[0 - 200 %]
Scale for the minimum output (0
mA or 4 mA) of the analog signal
at terminal 42.
Set the value to be the percentage
of the full range of the variable
selected in
parameter 6-50 Terminal
42 Output
.
6-52 Terminal 42 Output Max Scale
Range:
Function:
100 %
*
[0 - 200 %]
Scale the maximum output of the
selected analog signal at terminal
42. Set the value to the maximum
value of the current signal output.
Scale the output to give a current
lower 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 0–100% of the full-scale
output, program the percentage
value in the parameter, that is 50%
= 20 mA. If a current 4–20 mA is
required at maximum output
(100%), calculate the percentage
value as follows:
20 mA/desired maximum current x 100 %
i . e . 10 mA : 20
10 x 100 = 200 %

6-53 Terminal 42 Output Bus Control
Range:
Function:

[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.
If a timeout function is selected in
parameter 6-50 Terminal 42 Output
,
the output is preset to this level if a
fieldbus timeout occurs.
