4.2.7 Autotuning Mode
CAUTION
D Disconnect the load (machine, device) from the motor before autotuning.
The motor may turn, possibly resulting in injury or damage to equipment. Also, motor constants cannot be
correctly set with the motor attached to a load.
Autotuning automatically tunes and sets the required motor constants when operating in the open-loop or
flux vector control modes. Always perform autotuning before starting operation.
When the rated voltage, rated current, rated frequency, and number of poles listed on the motor nameplate
have been input and the RUN Key is pressed, the motor constants calculated from these values will be writ-
ten to E1-04 through E2-09 automatically.
When motor cannot be disconnected from the load, motor constants can be set by calculation.
Contact your Yaskawa representatives for details.
The autotuning mode won’t be displayed if V/f control has been selected. Refer to Setting the Control Meth-
od: A1-02 under 4.2.5 Initialize Mode.
The Inverter’s autotuning function automatically determines the motor constants, while a servo system’s
autotuning function determines the size of a load, so these autotuning functions are fundamentally different.
