8.2.5. Minor Servo Gain Adjustment (Adjustment Level 2)
！
Danger : Confirm that the work (or Motor) does not hit any obstacle when the
Motor makes a motion. Always stay in safe position.
à
This section describes minor servo-gain adjustment as the next step
when the Motor operation is not satisfactory with the automatic tuning.
à
Servo-gain can be adjusted by the parameter “SG”.
• Setting higher “SG” value improves response to the programmed
motion profile. However, if “SG” is too high, the Motor starts to
vibrate.
à
The same demonstration program in chapter 8.2.4 is used as the
example for adjusting “SG” value. (Execute same procedure a ~ j in
chapter 8.2.4 and keep operate the Motor.)
(1) Start “SG” adjusting program.

: Pressing key one time decreases 1 resolution of “SG”.
ENT : Store “SG” value to the memory.
(ii) Indicates present “SG” value.
(iii) Indicates “SG” value changed by pressing plus (+) or minus (-) key.
(iv) Response index number : The lower numbers denotes better response.
(v) Positioning index number : The lower number denotes quicker response.
Note: Do not use space key or back space key. When it is used, the “SG” changing resolution
(ii) may be altered.
