Examples of setting auto-tuning
Here are setting examples for each of the selections 1, 2 and 3 described in 6.20.
a) Combination with a Toshiba standard motor
I n ve r te r : VFA 7 - 2 037 PL
M ot or : 3 . 7[kW] , 4 P, 6 0[ H z ]
[Selection 1]
Set the automatic V/f mode setting parameter  at .
[Selection 2]
Set the motor control mode selection parameter  at  (Sensorless vector control).
[Selection 3]
Set the motor control mode selection parameter  at  (Sensorless vector control).
b) Combination with a Toshiba VF motor (4P motor with the same capacity as the inverter)
I n ve r te r : VFA 7 - 2 037 P L
M ot or : 3 . 7[kW] , 4 P, 6 0[ H z ]
[Selection 1]
Set the automatic V/f mode setting parameter  at .
[Selection 2]
1) Set the motor control mode selection parameter  at  (Sensorless vector control).
2) Set the auto-tuning  at .
[Selection 3]
1) Set the motor control mode selection parameter  at 3 (vector control).
2) Change the motor type  from  (Toshiba standard motor) to  (Toshiba VF motor).
(When using a Toshiba VF motor with a rated capacity smaller than that of the inverter,
properly change the setting of the motor rated capacity parameter .)
3) Set the auto-tuning  at .
c) Combination with a standard motor other than the above Toshiba motors
I n ve r te r : VFA 7 - 2 037 PL
M ot or : 2 . 2[kW] , 4 P, 5 0[ H z ]
[Selection 1]
Set the automatic V/f mode setting parameter  at .
[Selection 2]
1) Set the motor control mode selection  at  (Sensorless vector control).
2) Set the auto-tuning parameter  at .
[Selection 3]
1) Set the motor control mode selection  at  (Sensorless vector control).
2) Change the motor rated capacity parameter  from  to 
3) Set the motor type parameter  at  (default setting)
4) Set  at 
5) Set  at 
6) Set the motor pole number parameter  at 
7) Change the motor parameters ( , ), if needed.
