8. GENERAL GAIN ADJUSTMENT
8.5 Differences in auto tuning between MELSERVO-J2 and MELSERVO-J2-Super
8.5.1 Response level setting
To meet higher response demands, the MELSERVO-J2-Super series has been changed in response level
setting range from the MELSERVO-J2 series. The following table lists comparison of the response level
setting.

Note that because of a slight difference in gain adjustment pattern, response may not be the same if the
resonance frequency is set to the same value.
8.5.2 Auto tuning selection
The MELSERVO-J2-Super series has an addition of the load inertia moment ratio fixing mode. It also has
the addition of the manual mode 1 which permits manual adjustment with three parameters.
