Automatic Adjusting Function
The following figure shows an overview of automatic adjustment function
.
1)Real-time auto tuning
This function estimates load characteristic using motor speed and torque command, and automatically
specifies basic gain with regard to position control and speed control on the basis of inertia estimation
value. At the same time, setting time for positioning is reduced by adding an estimated friction torque to
a torque command in advance.
2)Adaptive filter
Estimating a resonance frequency using a motor speed and removing the frequency components from a
torque command suppresses vibrations caused by resonance.
