User Manual of EM730/EM730E Series Inverter This parameter can be adjusted to suppress motor oscillations during the open loop control (VVF). When the motor does not oscillate, this parameter should not be adjusted as little as possible or properly reduced. If the motor oscillates obviously, this parameter can be increased properly. This function is usually applied for load distribution when one load is driven by multiple motors.
Droop control is to reduce the output frequency of the inverter with the load increasing, so that the output frequency of the motor drops more in the load driven by multiple motors, thus reducing the load on this motor and leading to evener distribution of the load on multiple motors. This parameter refers to the output frequency drop of the inverter under the rated load. 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. energy saving conditions are met and have been maintained for the energy saving time (F05.17).
When energy-saving operation is valid, energy saving control will be enabled once the 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.
