User Manual of EM730/EM730E Series Inverter motor. F05.00=0: linear V/F It is suitable for ordinary constant-torque loads. F05.00=1: multi-point V/F relationship curve can be obtained by setting the parameters F05.01 to F05.06. It is suitable for special loads such as dehydrators, centrifuges and cranes. Any V/F F05.00=2/3: 1.3 th power/1.7 th power of V/F It is a VF curve between the linear VF and square VF. F05.00=4: square V/F It is suitable for centrifugal loads such as fans and pumps. F05.00=5: VF complete separation mode In this case, the output frequency and output voltage of the inverter are independent of each other.
The output frequency depends on the frequency source, and the output voltage is determined by F05.07 (VF separation voltage source). The VF complete separation mode is usually applied in induction heating, inverter power supply, torque motor control, etc. F05.00=6: VF semi-separation mode voltage source F05.07. In addition, the relationship between V and F is also related to the rated In this case, V and F are proportional, but their proportional relationship can be set by the voltage and rated frequency of the motor in the F1 group. Assuming that the voltage source input is X (X is 0 to 100%), the relationship between the output voltage V and frequency F of the inverter is:
