Value is taken from par. DR-37 Drive Max. Current. Inverter max. current (160% current) is equal to 20 mA.
The torque setting is related to setting in par. F-40 Torque Limiter (Driving).
The torque setting is related to the motor torque setting.
Taken from par. P-07 Motor Power [kW]
Taken from par. F-53 Maximum Reference. 20 mA = Value in par. F-53 Maximum Reference.
Torque reference related to 160% torque.
An output value set from Network process data. The output will work independently of internal functions

In relation to par. F-03 Max Output Frequency 1.
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 par.
AN-62 Terminal X30/8 Max. Scale if value is below 100%.
This parameter is active when option module OPCGPIO General Purpose I/O Option Module 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 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 maximum signal value. If 20 mA is the desired output
current at a value between 0 - 100% of the ful-scale output, program the percentage value in the pa-
rameter, i.e. 50% = 20 mA. If a current between 4 and 20 mA is desired at maximum output (100%),
calculate the percentage value as follows:
