Auto tuning function is designed to automatically measures
the motor constants necessary for Advanced magnetic flux
vector control, Real sensorless vector control, and vector
control operation.
The motor can be run with the optimum operating
characteristics even when each motor constants differs,
other manufacturer's motor is used, or the wiring length is
long.
What is auto tuning?
1) The motor performance can be maximized.
2) Auto tuning function is recommended for improvement of motor operation performance. (Always perform auto tuning when
using Real sensorless vector control.)
3) There are two different auto tuning: offline auto tuning (measures motor constants before machine operation) and online
auto tuning (measures motor constants at every start of the inverter).
4) Tuning without motor running and with motor running are available for offline auto tuning.
5) Accuracy of speed characteristics
Online offline (with motor running)

Also, tuning data (motor constants) can be copied to
another inverter with the operation panel or FR-PU07
parameter unit.
Note that a high-slip motor, high-speed motor, or other
special motor cannot be tuned. Also, the highest speed
should be 120Hz.
without tuning
By selecting a standard motor or constant torque motor, thermal
characteristic and motor constants of each motor are set.
Set the applied motor capacity.
V/F control
Set the number of motor poles.
