PARAMETERS
4.2.35 Offline auto tuning function (Pr. 82 to Pr. 84, Pr. 90, Pr. 96)
Pr. 82 "motor excitation current"
Pr. 83 "rated motor voltage"
Pr. 84 "rated motor frequency"
Pr. 90 "motor constant (R1)"
Pr. 96 "auto-tuning setting/status"
When you use the general-purpose magnetic flux vector control, you can perform the
offline auto tuning operation to calculate the motor constants automatically.
Offline auto tuning is made valid only when Pr. 80 is set to other than "9999" to select
the general-purpose magnetic flux vector control.
Offline auto tuning
Automatically measures the motor constants used for general-purpose magnetic flux
vector control.
• Offline auto tuning can be performed with the load connected.
• The offline auto tuning status can be monitored with the operation panel (FR-PA02
-
02
) or parameter unit (FR-PU04-MGI).
• Only a static auto tune can be performed.
• Offline auto tuning is available only when the motor is at a stop.
Tuning data (motor constants) can be copied to another inverter with the PU (FR-PU04-
MGI).
• You can read, write and copy the motor constants tuned by the offline auto tuning.
What is auto tuning?
(1) The general-purpose magnetic flux vector control system gets the best
performance from the motor for operation.
(2) Using the offline auto tuning function to improve the operational performance of
the motor.
