6.3.2 One-click Tuning
This function is able to automatically tune the most optimal gain parameters for the specific
applications after the axis is in operation and learning. Corresponding paths and
responsiveness level need to be set before using this function. Please refer to the flow chart
below. Parameter will be saved to parameters file and can be used on similar axes.
Recommended for applications where inertia changes is minute.
Recommended application scenarios
Control
mode
Suitable in position mode or EtherCAT mode (Not applicable in other modes)
Others
Make sure servo drive can't be enabled externally or any external
command that can rotate the motor. Set range of movement, velocity and
acceleration/deceleration time for one-click tuning.
Prohibit external command. Make sure there is no obstacle within the
range of movement of the axis and motor can rotate freely.
Factors affecting one-click tuning
Load inertia
External load smaller or 30 times larger than rotor inertia
Drastic changes in load inertia during motion.
Under heavy load (more than 30 times inertia), please make sure of safety
Load
Mechanical load is loosely connected.
Existence of gear backlash or any other non-linear factors
Complicated mechanical load structure
Motion
Range of movement is too short or too long which cost the time to be
overdue.
Not smaller than 0.5R
