2. Real-Time Auto-Gain Tuning
Two-degree-of-freedom Control Mode – Standard Type
How to Operate
When Pr 0.02 “Real-time auto-gain tuning setup” is set to a value other than 0, control
parameter is automatically set according to Pr0.03 “Selection of machine stiffness at
real-time auto-gain tuning” or Pr6.10 “Function expansion setup” bit14, the control
parameters are automatically set .
When the servo is ON, enter operation command after about 100ms. When the load
characteristic is correctly estimated, Pr 0.04 “Inertia ratio” is updated. With certain mode
settings, Pr 6.07 “Torque command addition value”, Pr 6.08 “Positive direction
compensation value”, Pr6.09 “Negative
direction torque compensation value”, and Pr6.50
“Viscous friction compensation gain” will be changed.
When value of Pr0.03 “Selection of machine stiffness at real-time auto-gain tuning” is
increased,
the motor responsiveness will be improved. Determine the most appropriate stiffness in
relation to the positioning setup time and vibration condition.
