z Offline auto tuning function (Pr. 82 to Pr. 84, Pr. 90 to Pr. 94, Pr. 96)
Pr. 82 "motor exciting current"
Pr. 83 "rated motor voltage"
Pr. 84 "rated motor frequency"
Pr. 90 "motor constant (R1)"
Pr. 91 "motor constant (R2)"
Pr. 92 "motor constant (L1)"
Pr. 93 "motor constant (L2)"
Pr. 94 "motor constant (X)"
Pr. 96 "auto tuning setting/status"
When you use the advanced magnetic flux vector control, you must perform the offline auto tuning operation
to calculate motor constants automatically.
z Offline auto tuning is made valid only when other values than "9999" are set in Pr. 80 and Pr. 81 to select
the advanced magnetic flux vector control.
z The offline tuning data (motor constants) can be copied to another inverter with the PU (FR-DU04/
FR-PU04).
z Offline auto tuning
Automatically measures the motor constants used for advanced magnetic flux vector control.
·
Offline auto tuning can be performed with the load connected. (As the load is smaller, tuning accuracy is
higher. Tuning accuracy does not change if inertia is large.)
·
For the offline auto tuning, you can select either the motor non-rotation mode or rotation mode.
Note that when making selection for the online auto tuning, the motor-only rotation mode should be
selected.
·
You can read, write and copy the motor constants tuned by the offline auto tuning.
·
The offline auto tuning status can be monitored with the PU (FR-DU04/FR-PU04).
Pr. 7 "acceleration time"
Pr. 9 "electronic overcurrent protection"
Pr. 71 "applied motor"
Pr. 80 "motor capacity"
Pr. 81 "number of motor poles"
Pr. 95 "online auto tuning selection"
Pr. 156 "stall prevention operation
selection"
