User Manual of A90 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 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 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. the 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 V/F=2*X* (rated voltage of the motor)/(rated frequency of the motor) 169 Function Function code Default Parameter description Unit Attribute code name setting F05.01 Frequency point F1 of multi-point VF 0.00 - F05.03 Hz 0.50 ● F05.02 Voltage point V1 of multi-point VF 0.0~100.0 (100.0 = Rated voltage) % 1.0 ● F05.03 Frequency point F2 of multi-point VF F05.01~F05.05 Hz 2.00 ● F05.04 Voltage point V2 of multi-point VF 0.0-100.0 % 4.0 ● F05.05 Frequency point F3 of multi-point VF F05.03 to rated frequency of motor (reference frequency) Hz 5.00 ● F05.06 Voltage point V3 of multi-point VF 0.0-100.0 % 10.0 ●
