5.9.4.1
Performing One Button Tuning
Overview
The "One Button Tuning" function (OBT) is an important component of basic commissioning.
Using this function, the mechanical drive train is measured using short test signals. Using this
measurement, the function optimally adapts the controller parameters to the mechanical
system being used. Further, this function allows you to determine optimum controller settings
with just a few entries.
Requirements
• There is an online connection to the drive unit.
• A servo drive is being used.
The function is not available for modules with vector control (e.g. S150).
• Function module "Advanced Position Control" (APC) is deactivated. Only use the APC
function after the controller optimization.
Restrictions
Observe the following restrictions before you carry out One Button Tuning:
• Only the motor measuring system is used to optimize the position controller. On the other
hand, using an external measuring system can result in an unstable controller setting.
• The function does not support different sampling times for the current controller and speed/
velocity controller. As a consequence, do not use the function for this type of configuration.
