Note: If the rigidity level is changed, the automatically set notch filter will be canceled. If vibration occurs, however, the
notch filter will be set again automatically.
(3) Alarm and Corrective Actions
The autotuning alarm (A.521) will occur if resonance sound is generated or excessive vibration occurs during
position control. In such case, take one of the following actions.
• Increase the setting of the rigidity level or reduce the load level in the Fn200 utility function.
• Increase the setting of Pn170.3 or reduce the setting of Pn170.2.
(4) Parameters Disabled by Tuning-less Function
When the tuning-less function is enabled in the factory settings, the settings of these parameters are not avail-
able: Pn100, Pn101, Pn102, Pn103, Pn104, Pn105, Pn106, Pn160, Pn139, and Pn408. These gain-related
parameters, however, may become effective depending on the executing conditions of the functions specified
in the following table. For example, if EasyFFT is executed when the tuning-less function is enabled, the set-
tings in Pn100, Pn104, Pn101, Pn105, Pn102, Pn106, and Pn103, as well as the manual gain switch setting,
will be enabled, but the settings in Pn408.3, Pn160.0, and Pn139.0 will be not enabled

Keys
Press the
tuning-less mode setting screen.
Press the
ity level.
Select the rigidity level from 0 to 4. The larger the
value, the higher the gain is and the better response
performance will be. (The factory setting is 4.)
Notes:
• Vibration may occur if the rigidity level is too high.
Lower the rigidity level if vibration occurs.
• If a high-frequency noise is heard, press the
Key to automatically set a notch filter to the vibra-
tion frequency.
Press the
mately two seconds and then "RUN" will be dis-
played. The settings are saved in the SERVOPACK.
Press the
tion. The screen in step 1 will appear again.
