Determining Tn
Tn determines the integral action time of the integral controller. The smaller Tn, the larger the gain of the Integral controllers. The correct value for Tn is mainly dependent on the type of coupling between motor and load. Many applications run satisfactorily with the default value Tn = 8 ms. At the Rigid coupling and if the tracking error appears to be too large, Tn can e.g. up to 5 ms.
