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. 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 the frequency converter.

Function:
Scale for the minimum output (0 or 4 mA) of the analogue signal at terminal 42.
Set the value to be the percentage of the full range of the variable selected in par. AN-50 Terminal 42
Output.
Function:
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 desired output current at a
value between 0 - 100% of the full-scale output, programme the percentage value in the parameter, 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:
100 % 20
i e mA x
. . 10 : 100 = 200 %
