IMPORTANT
Connect the Inverter to the motor when adjusting the user constants. However, the user constants cannot be
adjusted for a motor with a capacity two or more frames smaller than the Inverter.
Step No.

Description
1
Set o2-04 (kVA selection) to the capacity of the Inverter that you use.
2
Set A1-02 to the control method to be used. The value of the control method
should be set to the same value as when the constants were copied from the
Inverter to the Digital Operator.
3
Set A1-03 (Initialize) to 2220 (2-wire initialization) or 3330 (3-wire initializa-
tion).
This example is a typical setting for initialization by a 2-wire sequence.
4
If the mode is switched to the DRIVE after initialization has been completed,
the motor power setting display appears. Set T1-02 (Motor output power) to
the motor capacity of the connected motor.
This example is the setting for a 55 kW motor.
5
Press the Increment Key to view the shipping adjustment display. After con-
firming that the motor has been connected, press the RUN Key to start auto-
tuning.
Note: Do not touch the motor terminals. Although the motor does not rotate,
voltage is being supplied to the motor though the motor is not rotating.

–
After autotuning has been completed, use the copy function of the Operator to
copy the settings of the constants of the control board from the Operator to the
Inverter before replacing the board.
If the copy function is not available, change the setting of the constants manu-
ally.
7
If the mode is switched to the DRIVE, the frequency setting display appears,
and the operation becomes enabled.
