User Manual of EM730 Series Inverter should be performed separately at low and high speeds. During the actual operation, the speed regulator will automatically calculate the current PI parameters based on the current frequency. The speed PI parameters are P1 and T1 at the switching frequency 1, and P2 and T2 at the switching frequency 2. If the frequency is greater than the F06.04 switching frequency 1 and less than F06.05 switching frequency 2, the switching frequency 1 and switching frequency 2 will be subject to linear transition. See Fig. 7- 21. Fig. 7-21 Schematic Diagram of PI Parameters 1. The parameters F06.00 to F06.05 need to be adjusted carefully.
They should not be adjusted under normal circumstances. 2. While setting the switching frequency, note that the F06.04 switching frequency 1 must be less than or equal to the F06.05 switching frequency 2. Speed loop output filtering can reduce the impact on the current loop, but the value of F06.07 should not be too large. Otherwise, slow responses may be caused. Use the default settings under normal circumstances.
