5) Obtain the VG value that is 80% of VG at where the vibration stopped.
If the vibration stopped at VG4, 3.2 (4 × 0.8 = 3.2) shall be the value of the VG.
Set it to the parameter VG.
6) Decrease the VG setting to 3.2 by pressing the
－
key.


The changing parameter VG will clear the parameter SG (Servo gain) to SG0.

Setting of the parameter SG automatically sets the parameter PG (Position loop proportional
gain) and the parameter VG as described in the chapter “5.3.2 Minor Tuning of Servo Gains.”
As the parameter VG has been individually set in this section, not derived from a setting of the
parameter SG, the parameter SG is cleared to SG0.
