Adjustments
6.2
Tuning-less Function
The tuning-less function is enabled in the factory settings. If resonance is generated or excessive vibration
occurs, refer to
6.2.2 Tuning-less Levels Setting (Fn200) Procedure and change the set value of Pn170.2 for
the rigidity level and the set value in Pn170.3 for the load level.
6.2.1
Tuning-less Function
The tuning-less function obtains a stable response without manual adjustment regardless of the type of
machine or changes in the load.
(1) Enabling/Disabling Tuning-less Function
The following parameter is used to enable or disable the tuning-less function.
(2) Application Restrictions
The tuning-less function can be used in position control or speed control. This function is not available in
force control. The following application restrictions apply to the tuning-less function.
CAUTION
• The tuning-less function is enabled in the factory settings. A sound may be heard for a moment when the /
S_ON signal is turned ON for the first time after the servo drive is mounted to the machine. This sound
does not indicate any problems; it means that the automatic notch filter was set. The sound will not be
heard from the next time the /S_ON signal is turned ON. For details on the automatic notch filter, refer to
(3) Automatically Setting the Notch Filter on the next page.
• The servomotor may vibrate if the mass of the load is 30 times greater or more than that of the servomotor
in the mass ratio.

If vibration occurs, set the mode to 2 in Fn200 or lower the adjustment level.
