Function:
The torque setting is related to the motor
torque setting.
Taken from parameter 1-20 Motor Power [kW].
Taken from parameter 3-03 Maximum
Reference. 20 mA = value in
parameter 3-03 Maximum Reference.
Torque reference related to 160% torque.
An output value set from fieldbus process
data. The output works independently of
internal functions in the frequency
converter.

Parameter 4-54 Warning Reference Low
defines the behavior of the analog output in
case of bus timeout.

Range [Min.-Max.] 0% = 4 mA; 100% = 20
mA.
Parameter 3-00 Reference Range [-Max. -
Max.] -100% = 4 mA; 0% = 12 mA; +100% =
20 mA.
In relation to parameter 4-19 Max Output
Frequency.
Function:
Scales the minimum output of the selected analog
signal on terminal X30/8. Scale the minimum value
as a percentage of the maximum signal value. For
example, enter the value 25% if the output should
be 0 mA at 25% of the maximum output value.
The value can never exceed the corresponding
setting in parameter 6-62 Terminal X30/8 Max. Scale
if the value is below 100%.
This parameter is active when VLT
Purpose I/O MCB 101 is mounted in the frequency
converter.
Function:
Scales the maximum output of the selected
analog signal on terminal X30/8. 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

Function:
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, 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 − 4
i . e . 10 mA : x 100 = 160 %

Function:
[0 - 100 %] Holds the level of output X30/8 if controlled
by bus.
Function:
[0 - Holds the preset level of output X30/8.
If there is a fieldbus timeout and a timeout
function is selected in parameter 6-60 Terminal
X30/8 Output, the output is preset to this level.
Function:
Select the function of terminal X45/1 as an
analog current output.
When no signal on the analog output is
present.
0 Hz = 0 mA; 100 Hz = 20 mA.
Parameter 3-00 Reference Range [Min. -
Max.] 0% = 0 mA; 100% = 20 mA.
Parameter 3-00 Reference Range [-Max. -
Max.] -100% = 0 mA; 0% = 10 mA; +100%
= 20 mA.
The value is taken from
parameter 16-37 Inv. Max. Current. The
inverter maximum current (160% current)
is equal to 20 mA.
