For the system identification, it is important to enter the values of a possibly existing gear.
Then, the controller dimensioning can be selected, and the identification process of the
auto-tuning tool FAST can be started by way of the button
System identification with
controller dimensioning
. The data can be stored in an XML file for analysis.
After the system identification, the controller dimensioning can be changed anytime
without requiring a new system identification. Simply click the button
New controller
dimensioning
.
The expert mode can be used for the manual configuration of the stiffness of the speed
controller (
Speed controller stiffness
) and the overshooting of the position controller
(
Position controller overshooting
).
If the automatic controller dimensioning process fails, a brief change of the nominal
current (e.g. a reduction in the case of small drives with a low mass) in the
Motor data
menu can lead to a successful identification.
If the automatic identification (FAST) has not been successful, the system suggests
using the default parameters for the speed controller.
