7-4 Disabling the Automatic Gain 
Adjustment Function
This section explains how to disable realtime autotuning and the adaptive filter. These functions are 
enabled by default.
Disabling Realtime Autotuning
By setting the Realtime Autotuning Mode Selection (Pn21) to 0 or 7, the automatic estimation of the 
Inertia Ratio (Pn20) will stop and realtime autotuning will be disabled.
However, the estimated results of the Inertia Ratio (Pn20) will remain. If the Pn20 value is obviously 
incorrect, perform autotuning or set the calculated value manually after disabling realtime 
autotuning. 
 When disabling the automatic adjustment function, the RUN Command 
Input (RUN) must be turned OFF.
 To enable the Realtime Autotuning Mode Selection (Pn21), turn OFF the 
RUN Command Input (RUN), and then turn it back ON.
