Realtime Autotuning (RTAT) Parameter Table
*1. This is limited at the minimum value of 10 if a 17-bit absolute encoder is used.
*2. If realtime autotuning is performed in vertical axis mode or friction compensation and vertical axis
mode, the value will be 9999 until load characteristic estimation (estimation of the inertia ratio, torque
command value offset, and forward/reverse direction torque offset) is completed. The value will
change to 10000 after the load characteristic estimation is completed.
