Setting up Compax370 I11 T11 192-120101 N6 - March 20044.4.1.2 Damping of the speed controllerThe damping influences the target value overshoot magnitude and the decaytime constant of control loop oscillation.Nominal value: 100%On increasing the damping:Overshoot decreases. High frequency oscillation of the servo drive takes place asfrom a certain threshold value.On decreasing the damping:The target value overshoot of the actual value increases, and the actual valueoscillates for a longer time above and below the target value. As from a certainthreshold value the servo drive oscillates continuously.t1: target value2: actual value3: damping2100.3: Damping of the speed controllerUnit: % Range: 0 ... 500 Standard value: 100%The damping influences the target value overshoot magnitude and the decay time constantof control loop oscillation.4.4.1.3 Filter for speed valueCan be used to improve (filter) the rotation speed signal. The greater the value, thestronger becomes the filter effect. However, the rotation speed delay increaseswith this value, so that the maximum possible control loop dynamic range becomessmaller with values which are too large.! Set the value to 0 when using motors with SinCos.! In the case of large load inertia in relation to the moment of inertia of the motor, alarge value can achieve further improvement in the attainable stiffness.2100.5: Filter actual speed valueUnit: % Range: 0 ... 550 Standard value: 100%This is used to improve signals (filtering) of the speed control signal
