User Manual of EM730 Series Inverter F05.00=0: linear V/F It is suitable for ordinary constant-torque loads. F05.00=1: multi-point V/F It is suitable for special loads such as dehydrators, centrifuges and cranes. Any V/F relationship curve can be obtained by setting the parameters F05.01 to F05.06. 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 other.
The output frequency depends on the frequency source, and the output voltage is In this case, the output frequency and output voltage of the inverter are independent of each 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 In this case, V and F are proportional, but their proportional relationship can be set by the voltage source F05.07. In addition, the relationship between V and F is also related to the rated voltage and rated frequency of the motor in the F1 group. output voltage V and frequency F of the inverter is:
Assuming that the voltage source input is X (X is 0 to 100%), the relationship between the V/F=2*X* (rated voltage of the motor)/(rated frequency of the motor) 206 6: VF semi-separation mode (Ud = 0, Uq = K * t = F/Fe * 2 * voltage of separation voltage source) Function code Function code name Parameter description Unit Default setting Attribute Mailing address F05.01 Frequency point F1 of multi-point VF 0.00 ~ F05.03 Hz 0.50 ● 0x0501 F05.02 Voltage point V1 of multi-point VF 0.0 ~100.0 (100.0 = Rated voltage) % 1.0 ● 0x0502 F05.03 Frequency point F2 of multi-point VF F05.01~F05.05 Hz 2.00 ● 0x0503 F05.04 Voltage point V2 of 0.0~100.0 % 4.0 ● 0x0504
