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.

Torque % lim
4-20mA
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.
