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
(4P motor with the same capacity as the inverter)
Inverter : VFA7 - 2037PL
Motor : 3.7[kW], 4P, 60[Hz]
[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)
Inverter : VFA7 - 2037PL
Motor : 3.7[kW], 4P, 60[Hz]
[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
Inverter : VFA7 - 2037PL
Motor : 2.2[kW], 4P, 50[Hz]
[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.
