E6582175F-2163) Increasing starting torqueSetting of V/F control mode selection 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.:Automaticallyadjusts theamountof torqueboost.Output voltage(%)Base frequency voltageOutput frequency (Hz)Base frequency 0Note: This control system can oscillate and destabilize runs depending on the load. In this case, setV/F mode selection = (V/F constant) and increase manual torque boost .● Motor constant must be setIf the motor you are using is a 4P Toshiba standard motor which has the same capacity as the inverter, thereis basically no need to set the motor constant. There are three setting methods as mentioned below. In anymethod, set the following parameters according to the motor’s name plate. (Base frequency 1), (Base frequency voltage 1), (Motor rated capacity), (Motorrated current), (Motor rated speed)1) Simultaneous setting of auto torque boost and auto-tuning (f400=2)Set the basic parameter (Torque boost setting macro function) to . Refer to section 6.1.5 for details.2) Automatic settingSet the extended parameter (auto-tuning) to . Refer to section 6.25 selection 2 for details.3) Manual settingSet each motor constant. Refer to section 6.25 selection 4 for details.4) Vector control - increasing starting torque and achieving high-precision operation.Setting of V/F control mode selection to 3 (Vector control)Using sensorless vector control will provide the highest torque at the low speed ranges.(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.● Motor constant must be setIf the motor you are using is a 4P Toshiba standard motor which has the same capacity as the inverter, thereis basically no need to set the motor constant. There are three setting methods as mentioned below. In anymethod, set the following parameters according to the motor’s name plate. (Base frequency 1), (Base frequency voltage 1), (Motor rated capacity), (Motorrated current), (Motor rated speed)
