Description
Indicates no signal on the analog output.
0 Hz = 0 mA; 100 Hz = 20 mA.
Parameter 3-00 Reference Range [Min - Max] 0% = 0 mA; 100% = 20 mA
Parameter 3-00 Reference Range [-Max - Max] -100% = 0 mA; 0% = 10 mA; +100% = 20 mA.
The value is taken from parameter 16-37 Inv. Max. Current. The inverter maximum current (160%
current) is equal to 20 mA.
Example: Inverter normal current (11 kW) is 24 A. 160 %=38.4 A. Motor normal current is 22 A, the
readout is 11.46 mA.
20 mA × 22 A
= 11 . 46 mA
38 . 4 A
When the normal motor current is equal to 20 mA, the output setting of parameter 6-52 Terminal
42 Output Max Scale is:

The torque setting is related to the setting in parameter 4-16 Torque Limit Motor Mode.
The torque is related to the motor torque setting.
Taken from parameter 1-20 Motor Power [kW].
Taken from parameter 3-03 Maximum Reference. 20 mA equals the value in parameter 3-03 Maxi-
mum Reference.
Torque reference related to 160% torque.
0 Hz = 0 mA, parameter 4-19 Max Output Frequency = 20 mA.
An output value set from fieldbus process data. The output works independently of internal func-
tions in the drive.
Parameter 4-54 Warning Reference Low defines the behavior of the analog output in case of field-
bus timeout.
