PARAMETERS
4.13.3 Offline auto tuning (Pr. 71, Pr. 80 to Pr. 84, Pr. 90 to Pr. 94, Pr. 96, Pr. 450,
Pr. 453 to Pr. 463, Pr. 684, Pr. 859, Pr. 860
)
The motor performance can be maximized with offline auto tuning.
• What is offline auto tuning?
When performing advanced magnetic flux vector control, real sensorless vector control or vector control, the
motor can be run with the optimum operating characteristics by automaticaly measuring the motor constants
(offline auto tuning) even when each motor constants differs, other manufacturer's motor is used, or the wiring
length is long.
