Description
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.
16 mA × 22 A
= 13 . 17 mA

If the normal motor current is equal to 20 mA, the output setting of parameter 6-52 Terminal 42

The torque setting is related to the 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 Refer-
ence.
Torque reference related to 160% torque.
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.
Parameter 4-54 Warning Reference Low defines the behavior of the analog output in case of field-
bus timeout.
Analog output at 0 torque is 12 mA. Motoring torque increases the output current to maximum
torque limit 20 mA (set in parameter 4-16 Torque Limit Motor Mode). Generating torque decreases
the output to torque limit in generator mode (set in parameter 4-17 Torque Limit Generator Mode)
Example: Parameter 4-16 Torque Limit Motor Mode = 200% and parameter 4-17 Torque Limit Genera-
tor Mode = 200%. 20 mA = 200% motoring and 4 mA = 200% generating.
0 Hz = 0 mA, parameter 4-19 Max Output Frequency = 20 mA.
