14.2 Servo control
14-49
• MD3527 digit 3 (Pn81B digit 3) MASK_MFC_BANKSEL_0_3 (For each axis)
Meaning: Model Following Control (MFC) bank 3 mask
Setting value: (0 --- Model following control is enabled.)
1 --- Model following control is disabled.
Note: Since model following control is to be used only for positioning, dis-
able the bank 3 (for handle feed.)
• MD3055 (Pn119) LOOP_GAIN_MFC (For each axis)
Meaning: MFC gain (Model position loop gain)
Setting value: [0.1/s]
• MD3056 (Pn11A) DUMP_FACTOR_MFC (For each axis)
Meaning: MFC attenuation coefficient (Model loop gain correction)
Setting value: [0-1000]
• MD3059 (Pn11D) SPD_FF_GAIN_MFC (For each axis)
Meaning: MFC speed FF gain
Setting value: [0-1000]
• MD3060 (Pn11E) TRQ_FF_GAIN_MFC (For each axis)
Meaning: MFC torque FF gain
Setting value: [0-1000]
14.2.10 Stop vibration suppression
The following shows parameters relating to stop vibration suppression used for Servo axis.
If stop vibration is produced, decrease a setting value of the following parameter until the
vibration stops. (Lowest limit value: 50%)
Notice that stop vibration becomes decreased as the number of stages and the time constant
of torque filter settings are decreased.
If a vibration is still produced irrespective of this function, use the vibration-damping con-
trol shown in 14.2.11 "Vibration-damping control".
• MD3114 (Pn154) DAMP_RATIO_ANTIVIB_ON_STP (For each axis)
Meaning: Stop vibration suppression attenuation ratio
Setting value: [%]
Initial value: 100% (Function disabled)
Note: To eliminate stop axis Kv drop, set the parameter to 50% or higher.
Be careful that parameter settings are different from that for J300.
(Initial setting value is 0%.)
• MD3115 (Pn155) START_TIME_ANTIVIB_ON_STP (For each axis)
Meaning: Stop vibration suppression start time
Setting value: [ms]
Standard setting value: 1024 ms
