7.23 One-touch tuning (Fn303)
One-touch tuning is a method of inputting a speed command or position command from the upper unit and manually
making adjustments while running. By adjusting one or two values with the one-touch tuner, the relevant servo gain setting
is automatically adjusted.
The one-touch tuner function makes adjustments to the following items.
● Gain adjustment (speed loop gain, position loop gain, etc.).
● Filter adjustment (torque command filter,
notch filter).
● Friction compensation.
● Type A vibration suppression co
ntrol.
The one-touch tuning procedure is shown below.

tuning is ended when the effect is satisfactory.
