Setting parameters
You only have to change the factory default settings of the Imax controller if the inverter
tends to oscillate when it reaches the current limit or it is shut down due to overcurrent.

Setting
This parameter defines the nominal motor current from rating
plate.
This parameter defines motor overload current limit relative to
P0305 (rated motor current).
This parameter defines the proportional gain of the Imax con-
troller.
Range: 0.000 to 0.499 (factory default: 0.030)
This parameter defines the integral time constant of the Imax
controller. Setting P1341 to 0 disables the Imax controller.
Range: 0.000 to 50.000 (factory default: 0.300)
This parameter sets the proportional gain of Imax voltage
controller. If the output current (r0068) exceeds the maximum
current (r0067), the inverter is dynamically controlled by re-
ducing the output voltage.
Range: 0.000 to 5.499 (factory default: 0.250)
This parameter defines the integral time constant of the Imax
voltage controller.
Range: 0.000 to 50.000 (factory default: 0.300)
