2-4-3 Slight vibration suppression control
The slight vibration suppression control mode is used to reduce servo-specific ±1 pulse vibration at
the time of a stop. This mode produces an effect especially when the ratio of load inertia moment to
servo motor inertia moment is small (2 to 5 times). Note that when vibration is attributable to loose-
ness (such as gear backlash) or machine resonance, use the machine resonance suppression filter
in parameter No. 22. The slight vibration suppression control mode should be used after real-time
auto tuning or manual gain adjustment.
Usage
First, perform real-time auto tuning or manual gain adjustment so that vibration falls within ±2 to 3
pulses.
Set 1 in parameter No. 20 to enter the slight vibration suppression mode at the time of a
stop.
