The torque setting is related to setting in
4-16 Torque Limit Motor Mode.
The torque setting is related to the motor
torque setting.
Taken from 1-20 Motor Power [kW]
Taken from 3-03 Maximum Reference. 20 mA
= Value in 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.

In relation to 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, i.e. 0
mA (or 0 Hz) is desired at 25% of the maximum
output value and 25% is programmed. The value
can never be higher than the corresponding setting
in 6-62 Terminal X30/8 Max. Scale if value is below
100%.
This parameter is active when option module 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 desired maximum value of the current signal
