User Manual of EM730 Series Inverter The energy saving rate (F05.16) reflects the energy saving capacity. The larger the set value, the more energy will be saved. If the set value is 0.00, energy saving will be invalid. When energy-saving operation is valid, energy saving control will be enabled once the energy saving conditions are met and have been maintained for the energy saving time (F05.17). The default settings of the VF control optimization parameters of the synchronous motor are used under normal circumstances. On the basis of the VF separation voltage source setting, the set value of F05.20 changes at intervals of one minute in the power supply setting.
7.7 Vector Control Parameter Group of F06 Group 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. Users should adjust the above speed PI parameters according to the actual load characteristics.
Generally, as long as the system does not oscillate, ASR_P should be increased as much as possible, and then ASR_T should be adjusted, so that the system makes response fast, without excessive over-tuning. To enable fast dynamic responses of the system at low and high speeds, PI regulation 211 F05.17 Energy saving action time 1.00 ~ 60.00 s 5.00 ● 0x0511 Function code Function code name Parameter description Unit Default setting Attribute Mailing address F06.00 Speed proportional gain ASR P1 _ 0.00 ~100.00 12.00 ● 0x0600 F06.01 Speed integral time constant ASR T1 _ 0.000 ~ 30.000, 0.000:
