EA180 Series Servo Drive Users Manual Notch width and depth relationship diagram The factory value (2) of notch filter width is generally used. 10 5 0 -3 -5 -10 Depth 50, width 4 Depth 0, width 4 Depth 0, width 8 -15 -20 -25 -30 Notes for using notch filter Notch filter cannot be used in torque control mode. When the notch frequency is set as 5000, the notch filter is invalid. For the setting of the first and second notch filters, you can first obtain the third and fourth notch filters using the automatic mode, and then copy their parameters. Although there are 4 notch filters, it is recommended to use up to 2 notch filters at the same time, otherwise the vibration may increase.
When using an adaptive notch filter, if the vibration cannot be eliminated for a long time, please disable the drive in a timely manner. The relationship between gain adjustment and mechanical rigidity 10 100 1000 In order to improve mechanical rigidity, The machine should be firmly placed on the foundation so that it does not vibrate. High-rigidity couplings should be used. Use a wide synchronous belt, and the tension of the synchronous belt should be set within the allowable axial load range of the motor. Use a special reducer for servo or gears with small clearance. The low rigidity of the machine means that its inherent vibration (resonance frequency) is low.
Low mechanical rigidity will greatly affect the gain adjustment of servo. For machines with low rigidity, the responsiveness of servo cannot be adjusted too high (high gain). 6.10 Manual gain adjustment (basic) EA180 series servo drive has automatic gain adjustment function, but automatic gain adjustment may not meet the requirements due to constraints by load conditions, etc. Manual gain adjustment is recommended when the coordination between servo system and machinery is expected to have the best responsiveness and stability.

If the servo gain adjustment reaches the limit, vibration will also be caused. This can be improved only by reducing the gain or the torque command filter time.
