4. Calculate the remainder of the necessary motor parameters using the following
measurements:
5. Run the full algorithm with the parameters calculated above with flux loop and
access the table starting with the first point. The first point is the rated d-
component current I
d_rtd
. The value of this current must satisfy the following
inequality:
6. If the inequality in #17 is true, then continue to access the table. If the inequality
(17) is not true then recalculate all the motor parameters with new I
d_rtd
and
rerun.
System architecture allows only three parameters to be saved.
