4.2.28 Offline auto tuning function (Pr. 82 to Pr. 84, Pr. 90, Pr. 96)
Pr. 82 "motor exciting current"
Pr. 83 "rated motor voltage"

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.
!
The general-purpose magnetic flux vector control can be used without using the
offline auto tuning function but if the motor used is not Mitsubishi's standard motor or
Mitsubishi's constant-torque motor (e.g. motor of another company make) or the
wiring distance is long, the motor can be run with the optimum operating
characteristics by using the offline auto tuning function.
!
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. (As the load is
smaller, tuning accuracy is higher. Tuning accuracy does not change if inertia is
large.)
"
The offline auto tuning status can be monitored with the control panel or PU
(FR-PU04).
"
Only a static auto tune can be performed.
"
Office 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).
