14.2.11 Vibration-damping control
Use this function in order to suppress stationary vibrations ranging from about 50 Hz to 400
Hz at a Servo axis.
The following explains about parameters relating to vibration-damping control.
• MD3041 digit 3 (Pn10B digit 3) GAIN_SWITCH (For each axis)
Meaning: Vibration-damping control selection
Setting value: 0 --- Vibration-damping control disabled.
3 --- A-type vibration-damping control enabled.
(1 and 2 --- M1-type and M2-type vibration-damping control enabled.
You need to study separately whether or not to use those functions.)
• MD3050 (Pn114) SPD_DUMP_GAIN_ANTIVIBRATION (For each axis)
Meaning: Vibration-damping speed damping gain
Setting value: [%]
Note: Set the parameter to "0" before adjustment.
• MD3051 (Pn115) LPF_CONST_ANTIVIBRATION (For each axis)
Meaning: Vibration-damping low-pass filter time constant
Setting value: [0.01 ms]
• MD3052 (Pn116) HPF_CONST_ANTIVIBRATION (For each axis)
Meaning: Vibration-damping high-pass filter time constant
Setting value: [0.01 ms]
Standard setting value: The same value as MD3051 (Pn115)
• MD3071 (Pn129) OBSERVER_GAIN_ANTIVIBR (For each axis)
Meaning: Vibration-damping observer gain
Setting value: [Hz]
Standard setting value: 1/2 of vibration frequency
• MD3072 (Pn12A) LOAD_INERTIA_ANTIVIBR (For each axis)
Meaning: Vibration-damping observer inertia correction
Setting value: [%]
Standard setting value: 100
