3) Increasing starting torque
Setting of V/F control mode selection RV to (automatic torque boost control)
Detects load current in all speed ranges and automatically adjusts voltage output (torque boost) from inverter. This gives steady torque for stable runs.

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, be sure to set the parameters H to H properly.
Be sure to set H (rated current of motor) and H (rated speed of motor) correctly, as specified on the motor’s nameplate. For the setting of H
1)The motor constant can be automatically set
⇒For details, see selection 1 in 6.15.1.
2) Each motor constant can be set individually. | ⇒ For details, see selection 2 in 6.15.1. |
4) Vector control - increasing starting torque and achieving
Setting of V/F control mode selection RV to (Vector control)
Using
(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.
