Autotuning Mode

Autotuning automatically tunes and sets the required motorparameters when operating in the open-loop or
flux vector control modes. Always perform autotuning before starting operation.
When the motor can not be disconnected from the load, perform stationary autotuning. Contact your dealer to
set motorparameters by calculation.
The Inverter's autotuning function automatically determines the motor parameters, while a servo system's
autotuning function determines the size of a load, so these autotunig functions are fundamentally different.

Example of Operation
Set the motor output power (in kW) and rated current specified on the nameplate on the motor and then press
the RUN key. The motor is automatically run and the motor line-to-line resistance measured based on these
settings will be set.
Always set the above items. Autotuning cannot be started otherwise.
Parameters can be changed from the setting displays. Use the Increment, Decrement and Digit Selection/
RESET keys to change the frequency. The parameter will be written and the display will be returned to moni-
tor display when the ENTER key is pressed after changing the setting.
