Toshiba VF-A7 Examples of setting auto-tuning, Inverter VFA7 2037PL Motor 7kW, 4P, 60Hz Selection

■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.
