Parameter Descriptions
6-50 Terminal 42 Output
Option: Function:
[137] Speed Taken from parameter 3-03 Maximum
4-20mA Reference. 20 mA = value in
parameter 3-03 Maximum Reference.
[139] Bus ctrl. An output value set from fieldbus process
0-20 mA data. The output works independently of
internal functions in the frequency
converter.
[140] Bus ctrl. An output value set from fieldbus process
4-20 mA data. The output works independently of
internal functions in the frequency
converter.
[143] Ext. CL 1
4-20mA
[150] Max Out Fr 0 Hz = 0 mA, parameter 4-19 Max Output
4-20mA Frequency = 20 mA.
[254] DC Link
0-20mA
[255] DC Link Enable the function of outputting the DC-
4-20mA 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 %
20
i . e . 10 mA : x 100 = 200 %

[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.
