E6582175F-126When vector control cannot be programmed....First read the precautions about vector control in section 6.3.9).1) If the desired torque cannot be obtained Refer to section 6.25 selection 22) If auto-tuning error "" appears Refer to section 6.25 selection 4 (Torque boost setting macro function) and (V/F control modeselection)Automatic torque boost is the parameter for setting V/F control mode selection () and auto-tuning() together. That is why all parameters related to change automatically when is changed.Automatically programmed parameters Displays after resetting - Check the programmed value of . - Automatic torque boost +auto-tuning Automatic torque boost control Auto-tuningexecuted(after execution: 0) Vector control + auto-tuning Vector control Auto-tuningexecuted(after execution: 0) Energy saving + auto-tuning Energy-saving Auto-tuningexecuted(after execution: 0)4) Increasing torque manually (V/F constant control)This is the setting of constant torque characteristics that are suited for such things as conveyors. It can alsobe used to manually increase starting torque.If V/F constant control is programmed after changing ,Set V/F control mode selection = (V/F constant). Refer to section 6.3Note 7: To further increase torque, increase the torque boost value 1().How to set the torque boost value 1() Refer to section 6.4Note 8: V/F control selection = 1 (variable torque) is an effective setting for load such as fans andpumps. Refer to section 6.3
