5.2.2 Tuning-less Levels Setting (Fn200) Procedure
(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 the following actions.
• 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
