User Manual of EM730 Series Inverter The running terminal is closed, F00.03 is set to 0 or 1, and the terminal is powered on during start/stop or cannot directly run once enabled by switching the start/stop mode. It is necessary to first disconnect the running terminal and then close it to start running. F04.27=2: When the output frequency is lower than the zero speed judgment frequency, the terminal “zero-speed running” will be valid. When the synchronous motor is used (e.g. F01.00=2) and subjected to VF control, the initial angle is essential for the control performance. In particular, reversing may occur at the moment of start.
Thus, the initial position is searched by default after power-on or protection, in order to achieve a better control performance. 7.6 VF Control Parameter Group of F05 Group The function codes in this group are valid for V/F control and invalid for vector control. V/F control is suitable for general-purpose loads such as fans and pumps, or when multiple motors are driven by one inverter or the power of the inverter is quite different from that of the motor.
