Motor Current Stabilization Adjustment; Torque Control; Torque Command - Toshiba TOSVERT VF-AS1 Instruction Manual

Examples of setting the motor constants
Here are setting examples for each of the selections 1, 2 and 3 described in Section 6.22.
a) Combination with a Toshiba standard motor (4P motor with the same capacity as the
inverter)
Inverter : VFAS1-2037PL
Motor : 3.7kW-4P-60Hz
[Selection 1]
Set the automatic torque boost () at .
[Selection 2]
1) Set the V/f control mode selection  at  (Sensorless vector control).
2) Set the auto-tuning () at . (When the cable length is 30m or over.)
b) Combination with a standard motor other than the above Toshiba motor
Inverter : VFAS1-2037PL
Motor : 2.2kW-2P-50Hz
[Selection 1]
Set the automatic torque boost () at .
[Selection 2]
1) Set the V/f control mode selection  at  (Sensorless vector control).
2) Set , , ,  and , as specified on the motor nameplate.
3) Set the auto-tuning () at .
4) Set the auto-tuning () at .
