Because the motor characteristics are generally unknown, the Sinus Penta is capable of automatically determining the
motor characteristics (see the FIRST STARTUP section and the AUTOTUNE MENU).
However, some parameters may be manually adjusted to meet the requirements needed for special applications.
The parameters used for the different control algorithms are stated in the table below.

NOTE
Because the value of the stator resistance is used for any type of control,
always perform the autotune procedure with
I073
= Motor Tune and
I074
= 0: All
no rotation.
