6.4 One-touch tuning
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 bandwidth setting, the relevant servo gain
setting is automatically adjusted.
The one-touch tuner makes adjustments to the following items.
⚫
Gain adjustment (velocity loop gain, position loop gain, etc.).
⚫
Filter adjustment (torque command filter, notch filter).
⚫
Friction compensation.
⚫
Type A vibration suppression control.
If you cannot obtain satisfactory response characteristics by intelligent setting, use one-touch tuning. If you want to further
fine-tune the gain of each servo after the one-touch tuning, refer to "Manual tuning function" to perform manual tuning.
If the setting is not correct, "NO-OP" will be displayed in the operation and the function cannot be executed. Before
performing the bandwidth setting, be sure to check the following settings.
⚫
Adjustment-free function selected as disabled (Pn175.X=0)
⚫
When tuning is performed via speed control, the tuning mode is set to 0 or 1
One-touch tuning is turned on by:
⚫
Keypad panel "
⚫
"One-touch tuning" of the host computer.
Precautions
●
Set the rotational inertia ratio (Pn100) correctly before performing one-touch tuning.
