User Manual of EM730 Series Inverter The injection current depends on F06.29 in the low frequency band (output frequency Fig. 7-22 Schematic Diagram of High Frequency Injection F06.32). To get better results, the gain and integral time of the regulator can be adjusted. Default settings can be used under normal circumstances. They must not be adjusted by non-professionals. changing the speed proportional gain (ASR_P) and speed integral time (ASR_T) of the speed PI In the vector control mode, the dynamic speed response of the inverter is adjusted by regulator. The increase in ASR_P or decrease in ASR_T may accelerate the dynamic response of the speed loop.
If ASR_P is too large or ASR_T is too small, however, the system may be over-tuned to cause oscillation. In case of any change in F06.37, the default values of F06.00-F06.03 will change accordingly. The adjustment intensity of the speed PI regulator can be changed.
