[133] Motor cur. 4-20mA Value is taken from par. 16-37 Inv. Max. Current . Inverter max. current (160% current) is equal to
20 mA.
Example: Inverter norm current (11 kW) = 24 A. 160 % = 38.4 A. Motor norm current = 22 A Read-
out 11.46 mA.

[138] Torque 4-20mA Torque reference related to 160% torque.
[139] Bus ctrl. 0-20 mA An output value set from fieldbus process data. The output will work independently of internal
functions in the frequency converter.
[140] Bus ctrl. 4-20 mA An output value set from fieldbus process data. The output will work independently of internal
functions in the frequency converter.
[141] Bus ctrl 0-20mA t.o. Par. 4-54
Warning Reference Low defines the behaviour of the analog output in case of bus time-
out.

Warning Reference Low defines the behaviour of the analog output in case of bus time-
out.
[149] Torque % lim 4-20mA Analogue output at zero torque = 12 mA. Motoric torque will increase the output current to max
torque limit 20 mA (set in par. 4-16
Torque Limit Motor Mode ).
Generative torque will decrease the output to torque limit Generator Mode (set in par. 4-17
Torque
Limit Generator Mode
)
Ex: par. 4-16
Torque Limit Motor Mode : 200% and par. 4-17 Torque Limit Generator Mode : 200%.
20 mA = 200% Motoric and 4 mA = 200% Generatoric.

Range: Function:
0.00 %* [0.00 - 200.00 %] Scale for the minimum output (0 or 4 mA) of the analogue signal at terminal 42.

6-52 Terminal 42 Output Max Scale
Range: Function:
100.00 %* [0.00 - 200.00 %] Scale the maximum output of the selected analog signal at terminal 42. Set the value to the maxi-
mum 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
