(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.
- Resonance Sound
In the S, reduce the setting of the Response level.
- Excessive Vibration during Position Control
Take one of the following actions to correct the problem.
In the S, reduce the setting of the Response level.
Increase the setting of Pn170.3 (Load level) 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
