6.6.2 STUNE
The servo tuning requirements are completed through a single parameter setting, the load inertia ratio is
adaptively identified, and the resonance suppression parameters are automatically set, which greatly reduces
the difficulty of debugging and improves the tuning
STune performs gain auto-tuning based on the set stiffness level H09-01. It aims to fulfill the requirements of
rapidity and stability.
The servo tuning requirements are completed through a single parameter setting, the load inertia ratio is
adaptively identified, and the resonance suppression parameters are automatically set, which greatly reduces
the difficulty of debugging and improves the tuning
The STune function is enabled by default with H09-00 (Gain auto-tuning mode) being set to 4 (Normal
mode+Inertia auto-tuning). The servo drive is turned off automatically 10 min after command input.
The STune function is intended to be used in applications featuring slight load inertia changes. For applications
featuring dramatic inertia changes or where inertia auto-tuning is unavailable (due to operating speed too low
or acceleration rate too small), disable the STune function after initial power-on.
