5.2 Tuning-less Function
The tuning-less function is enabled in the factory settings. If resonance is generated or excessive
vibration occurs, refer to
5.2.2 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.
CAUTION
• The tuning-less function is enabled in the factory settings. A sound may be heard for a moment when
the SV_ON command is received 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 SV_ON command is received. 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 load moment of inertia exceeds the allowable load value. If vibration
occurs, set the mode to 2 in Fn200 or lower the adjustment level.
5.2.1 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.
