Speed control response constant

Contents and display

Set the response speed (ASR system gain) between the inverter and motor. When increasing

or decreasing the current motor response speed, adjust the ASR system gain. When the set value is decreased, the response speed is increased. When the set value is increased, the response speed is decreased.
