Autotune results
At the end of a successful autotune routine, its results are automatically
transferred into parameters
•
(proportional gain of the speed controller)
•
(integration time of the speed controller)
•
(derivation time of acceleration(/deceleration) compensation)
•
(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.
Warning indications
A warning message
, will be generated if the autotune routine does not
complete successfully. See chapter
(page
