User Manual of EM730/EM730E Series Inverter Output voltage Rated voltage (%) of motor V3 V2 V1 F1 F2 F3 Rated frequency Output frequency （ % ） Fig. 7-19 Schematic Diagram of Multi-point Polyline V/F Curve of motor VF separation is usally applied in induction heating, inverter power supply, torque motor control, etc. When VF separation control is selected, the output voltage can be set by the function code F05.08 or according to the analog, high-speed pulse, PID or communication settings. For non-digital settings, 100% of each setting corresponds to the rated voltage of the motor.
When the percentage set by the analog output is negative, the set absolute value will be taken as the valid set value. F05.07=0: digital setting of VF separation voltage (F05.08) (F05.08). The VF separation output voltage depends on the digital setting of VF separation voltage F05.07=1:AI1 188 Function Default Function code name Parameter description Unit Attribute code setting F05.07 Voltage source of VF separation mode 0: digital setting of VF separation voltage 1: AI1 2: AI2 3: retention 4: High-frequency pulse (X5) 5：PID 6: Communication setting Note: 100% is the rated voltage of the motor.
