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
