Real-time auto tuning

Note
Under operating conditions that impose sudden disturbance torque during
acceleration/deceleration or on a machine that its rigidity is poor, auto tuning may not
function properly, either. In such cases, use one-button auto tuning or manual tuning to
optimize the drive.
With real-time auto tuning, the servo drive can automatically estimate the ratio of load
moment of inertia and set the optimum control parameters.
Pre-conditions for the real-time auto tuning
● The drive must be controlled by the host controller.
● The machine actual load moment of inertia is different when the machine moves to the
different positions.
● Make sure that the motor has multiple accelerations and decelerations. Step command is
recommended.
● Machine resonance frequency changes when the machine is running.
Implement the following steps to use the real-time auto tuning function:
