"Nettetthe motor rating. A common misconception is to set the Maximum current parameter equal to the motor’s current rating. This is not recommended, as this would interfere with the VFD’s motor overload protection (I2t). The Maximum current parameter setting should be left at factory default unless the equipment requires current limit protection. " - Motor rated tolerance torque
