E6581595F-406Setting procedure Adjust the following parameters:: Set the compensation gain for the slipping of the motor. A higher slip frequency reduces motorslipping correspondingly. After setting , set  to adjust in detail. Be careful asinputting a value larger than necessary causes hunting and other unstable operation.: Adjust the primary resistive component of the motor. Decreases in torque due to a possible voltagedrop during low-speed operation can be suppressed by setting a large value in this parameter. Becareful as setting a value larger than necessary may lead to an increased current causing a trip atlow speeds. (Perform adjustments according to the actual operation.): Set the the motor's rated capacity according to the motor's name plate or test report.: Set the rated current of the motor. For the rated current, see the motor's nameplate or test report.: Set the ratio of the no-load current of the motor to the rated current. Enter the value in % that isobtained by dividing the no-load current specified in the motor's test report by the rated current.Increasing this value increases the excitation current.: Set the rated rotational speed of the motor. For the rated current, see the motor's nameplate or testreport.+ Adjustment method for the moment of inertia of the load: Adjusts the excess response speed. A larger value gives a smaller overshoot at theacceleration/deceleration completion point. In the default settings, the moment of inertia of the load(including the motor shaft) value is optimally set considering a motor shaft of 1x. When themoment of inertia of the load is not 1x, set a value that matches that actual moment of inertia ofthe load. : If the rated capacity of the motor is one size smaller than that of the inverter, lower the thermalprotective level according to the rated current of the motor.* Sensorless vector control may not operate properly if the motor capacity differs from theapplicable rated capacity of the inverter by more than two grades.Caution:If a combination of the inverter rating and the motor capacity is different for more than 2 items, vectorcontrol may not operate correctly.Note 1: , , , , , , , , and  (Motorspecific coefficient 1-9) are parameters for manufacturer settings.
