Release of Automatic Gain Adjusting Function
Outline
Cautions are described when you want to invalidate the real time auto-gain tuning of default or the adaptive filter.
Caution
Execute the release of the automatic adjusting functions while all action stop (Servo-OFF)
Invalidation of Real-Time Auto-Gain Tuning
You can stop the automatic calculation of Pr20 (Inertial ratio) and invalidate the real-time auto-gain tuning by
setting up Pr21 (Real-time auto-gain tuning setup) to 0.
Note that the calculation result of Pr20 (Inertia ratio) will be held, and if this parameter becomes abnormal
value, use the normal mode auto-gain tuning or set up proper value manually obtained from formula or
calculation.
Invalidation of Adaptive Filter
When you set up Pr23 (Setup of adaptive filter) to 0, adaptive filter function which automatically follows the
load resonance will be invalidated.
If you invalidate the adaptive filter which have been working correctly, noise and vibration may occur due to
the effect of resonance which have been suppressed.
Therefore, execute the copying function of the setup of adaptive filter (Pr2F) to the 1st notch frequency
(Pr1D) from the Fit-gain screen of the front panel (refer to P.72, "Fit-Gain Screen" of Preparation), or set up
Pr1D (1st notch frequency) manually by using the table below, then invalidate this filter.
