10.2 Autotuning
Overview
The term "A
utotuning" comprises all converter-internal functions that adapt controller
parameters during operation based on internal measured variables. The settings are written to
the parameters, but are not saved permanently.
Description of function
Applications
The autotuning function is applicable to the following scenarios:
• Support of the commissioning
• Adaptation of the controller to major changes in the mechanical system
Available modes
The autotuning function is activated/deactivated with parameter p5300. The following
autotuning modes are available for the converter:
• One Button Tuning
With this procedure, the speed controller and position controller can be automatically tuned
(optimized). In this regard, the servo drive system is measured once and the controller is then
set.
• Real Time Tuning
With this procedure, controller parameters are determined from the constantly estimated or
parameterized moments of inertia.
Deactivate Real Time Tuning as soon as the controller data has been calculated and the
established values for controller optimization, as well as the lter settings have been saved
in a non-volatile memory.
