Autotune results
At the end of a successful autotune routine, its results are automatically
transferred into parameters
25.02
• (proportional gain of the speed controller)
25.03
• (integration time of the speed controller)
25.06
• (derivation time of acceleration(/deceleration) compensation)
25.37
• (mechanical time constant of the motor and machine).
Nevertheless, it is still possible to manually adjust the controller gain,
integration time and derivation time.
The figure below is a simplified block diagram of the speed controller. The
controller output is the reference for the torque controller.
