<Operating conditions>
·
The motor is connected.
·
The motor capacity is equal to or one rank lower than the inverter capacity.
·
The maximum frequency is 120Hz.
·
Special motors such as high-slip motor and high-speed motor cannot be tuned.
·
When "101" (offline auto tuning with motor running) is set in Pr. 96, note the following:
1) Torque may not be enough during tuning.
2) The motor may be run at nearly its rated frequency (Pr. 84 setting) without problem.
3) The brake is open.
4) No external force is applied to rotate the motor.
·
If "1" (tuning without motor running) is set in Pr. 96, the motor may run slightly. Therefore, fix the motor
securely with a mechanical brake, or before tuning, make sure that there will be no problem in safety if the
motor runs.
This instruction must be followed especially for vertical lift applications.
Note that if the motor runs slightly, tuning performance is unaffected.
Note: Offline auto tuning will not be performed properly if it is performed when the reactor or surge
voltage suppression filter is connected between the inverter and motor.
Remove it before starting tuning.

Parameter setting
·
Using Pr. 80 and Pr. 81, select the advanced magnetic flux vector control.
·
Refer to the parameter details list and set the following parameters:
1) Set "1" or "101" in Pr. 96.
·
For setting of "1" ................................................................................Tuning without motor running.
·
For setting of "101" ............................................................................Tuning with motor running.
2) Set the rated motor current (A) in Pr. 9.
3) Set the rated motor voltage (V) in Pr. 83.
4) Set the rated motor frequency (Hz) in Pr. 84.
5) Select the motor using Pr. 71.
·
Standard motor ..................................................................................Pr. 71 = "3"
·
Constant-torque motor....................................................................... Pr. 71 = "13"
Note: Pr. 83 and Pr. 84 are only displayed when the advanced magnetic flux vector control is
selected (Pr. 80, Pr. 81).
In these parameters, set the values given on the motor plate.
