n L3-36/L3-41: Vibration Suppression Gain during Acceleration/Deceleration (with Current Limit)There is normally no need to change these parameters from their default values. These parameters are valid when accelerationstall prevention (with current limit) is enabled (L3-01 = 3), or when current-limited deceleration is selected for stall preventionduring deceleration (L3-04 = 6). Increase the setting values if oscillation occurs in the output current during acceleration/deceleration.No. Name Setting Range DefaultL3-36 Vibration Suppression Gain during Acceleration(with Current Limit) 0.0 to 100.0 Determined byA1-02L3-41 Vibration Suppression Gain during Deceleration(with Current Limit) 1.0 to 1000.0 Determined byA1-02n L3-39/L3-44: Current-Limited Integral Time Constant during Acceleration/DecelerationSet the time constant for acceleration/deceleration rate adjustment for current-limited acceleration/deceleration.
