The torque setting is related to setting in
parameter 4-16 Torque Limit Motor Mode.
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.

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, 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.
