Panasonic A4P Series Invalidation of Real-Time Auto-Gain Tuning, SV.Pr2F 1st notch frequency Hz

Release of Automatic Gain Adjusting Function [Adjustment]

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 SV.Pr20 (Inertial ratio) and invalidate the real-time auto-gain tuning by setting up SV.Pr21 (Real time auto tuning set up) to 0.

Note that the calculation result of SV.Pr20 (Inertia ratio) will be held, and if this parameter becomes abnor- mal 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 SV.Pr23 (Adaptive filter mode) 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 (SV.Pr2F) to the 1st notch frequency (SV.Pr1D), or set up SV.Pr1D (1st notch frequency) manually by using the table below, then invalidate this filter.
