Motor Constant Must Be Set; Vector Control - Toshiba TOSVERT VF-nC3E Instruction Manual

★ Motor constant must be set

If the motor you are using is a 4P Toshiba standard motor and if it has the same capacity as the inverter,
there is basically no need to set the motor constant. In any other case, set the following parameters
according to the motor's name plate.
 (Base frequency 1),  (Base frequency voltage 1),  (Motor rated capacity),  (Motor
rated current),  (Motor rated speed)
There are three procedures for setting the other motor constants.
1) Auto torque boost and a motor constant (auto-tuning) can be set at once.
To do so, set the basic parameter  to .
2) The motor constant can be automatically set (auto-tuning).
Set the extended parameter  to .
3) Each motor constant can be set individually.
4) Vector control - increasing starting torque and achieving high-precision operation.
Using sensor-less vector control will provide the highest torque at the low speed ranges.
5
(1) Provides large starting torque.
(2) Effective when stable operation is required to move smoothly up from the low speeds.
(3) Effective in elimination of load fluctuations caused by motor slippage.

There are three procedures for setting the other motor constants.
1) The sensorless vector control and motor constants (auto-tuning) can be set at a time.
Set the basic parameter  to .
2) The motor constant can be automatically set (auto-tuning).
Set the extended parameter  to .
3) Each motor constant can be set individually.
