5-16 Operation MN1903 5.5 Servo axis - tuning for current control 5.5.1 Selecting servo loop gains All servo loop parameters default to zero, meaning that the demand output will be zero atpower up. Most servo amplifiers can be set to current (torque) control mode or velocity controlmode; check that ...

Operation 5-17 MN1903 3. Click in the KPROP box and enter a value that is approximately one quarter of the valueof KDERIV. If the motor begins to vibrate,decrease the value of KPROP or increasethe value of KDERIV until the vibration stops.Small changes may be all that is necessary. 4. In the Move Ty...

5-18 Operation MN1903 5.5.2 Underdamped response If the graph shows that the response is underdamped (it overshoots the demand, as shown inFigure 12) then the value for KDERIV should be increased to add extra damping to the move.If the overshoot is excessive or oscillation has occurred, it may be ne...

Operation 5-19 MN1903 5.5.3 Overdamped response If the graph shows that the response is overdamped (it reaches the demand too slowly, asshown in Figure 13) then the value for KDERIV should be decreased to reduce the damping ofthe move. If the overdamping is excessive, it may be necessary to increase...

5-22 Operation MN1903 5.7 Servo axis - tuning for velocity control Drives designed for velocity control incorporate their own velocity feedback term to providesystem damping. For this reason, KDERIV (and KVEL) can be set to zero. Correct setting of the velocity feed forward gain KVELFF is important ...
