60 LPF Low-pass filter/adaptive vibration suppression control
Used to selection the low-pass filter and adaptive vibration suppression
control. (Refer to Chapter 7.)
0
Low-pass filter selection
0: Valid (Automatic adjustment)
1: Invalid
When you choose "valid",

VG2 setting 10
bandwidth filter is set automatically.
Adaptive vibration suppression control selection
Choosing "valid" or "held" in adaptive vibration
suppression control selection makes the machine
resonance control filter 1 (DRU parameter No. 58) invalid.
0: Invalid
1: Valid
Machine resonance frequency is always detected
and the filter is generated in response to resonance to
suppress machine vibration.
2: Held
The characteristics of the filter generated so far are held,
and detection of machine resonance is stopped.
Adaptive vibration suppression control sensitivity selection
Used to set the sensitivity of machine resonance detection.
0: Normal
1: Large sensitivity

Gain changing selection
Gains are changed in accordance with the settings
of DRU parameters No. 61 to 64 under any of the
following conditions:
0: Invalid
1: Gain changing (CDP ) is ON
2: Command frequency is equal to higher than
DRU parameter No. 66 setting
3: Droop pulse value is equal to higher than
DRU parameter No. 66 setting
4: Servo motor speed is equal to higher than
DRU parameter No. 66 setting
