User Manual of EM730/EM730E Series Inverter Injection current F06.29 High frequency band F06.33 Frequency 0 F06.28 F06.32 Fig. 7-22 Schematic Diagram of High Frequency Injection The injection current depends on F06.29 in the low frequency band (output frequency 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. In the vector control mode, the dynamic speed response of the inverter is adjusted by changing the speed proportional gain (ASR_P) and speed integral time (ASR_T) of the speed PI 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. There are 21 optional groups of parameters in total. The larger the set value of F06.37, the larger the proportional gain is, the smaller the integral time is, and the more intense the speed PID regulation is. The smaller the set value of F06.37, the weaker the speed PID regulation is.
