Configuration
The Position Loop screen also includes a table of Additional Parameters, which
are relevant to current but not to control. You can modify these parameters in
the same way you work with parameters in the Drive Parameters screen. Refer
to Section ‎4.5.1 and to the LVD VarCom Reference Manual.
To verify the behavior of the position control loop, go to the Motion screen, and
use the Position Profile tab to test the current loop step response. Refer to
Section ‎4.6.10.
4.6.9 Control Loop Tuning
Each control loop screen has a Tune button that activates a dedicated Tuning
utility. Each Tuning screen enables you to adjust the relevant control loop gains
and parameters in order to achieve the desired performance.
Figure ‎4-19 shows, for example, the Tuning screen for the Current control loop.
Figure ‎4-19. Tuning Screen for Current Loop
Clicking the Test button initiates a step command. The tuning screen displays
the response to the command with the gains currently configured.
Warning: Use with caution. As soon as the Test button is pressed, Axis Manager
activates the selected control loop and enables the drive, and the motor will
begin to move.
The tuning screen also displays information such as rise time and overshoot for
the step response.
