[Selection 2: Setting vector control and auto-tuning independently]
Set vector control, automatic torque boost, and energy saving and auto-tuning individually.
After setting  (V/F control mode selection), auto-tuning occurs.
Set the auto-tuning parameter  to  (Auto-tuning enabled)

Auto-tuning

Set f400 to 2 to before the start of operation. Tuning is performed at the start of the motor.

★ Precautions on auto-tuning

(1) Conduct auto-tuning only after the motor has been connected and operation completely stopped.
If auto-tuning is conducted immediately after operation stops, the presence of a residual voltage
may result in abnormal tuning.
(2) Voltage is applied to the motor during tuning even though it barely rotates. During tuning,
"" is displayed on the operation panel.
(3) Tuning is performed when the motor starts for the first time after f400 is set to 2 .
Tuning is usually completed within three seconds. If it is aborted, the motor will trip with the dis-
play of  and no constants will be set for that motor.
(4) High-speed motors, high-slip motors or other special motors cannot be auto-tuned. For these
motors, perform manual tuning using Selection 3 described below.
(5) Provide cranes and hoists with sufficient circuit protection such as mechanical braking. Without
sufficient circuit protection, the resulting insufficient motor torque during tuning could create a risk
of machine stalling/falling.
(6) If auto-tuning is impossible or an "" auto-tuning error is displayed, perform manual tuning
with Selection 3.
[Selection 3: Setting vector control and manual tuning independently]
If an "" tuning error is displayed during auto-tuning or when vector control characteristics are to be
improved, set independent motor constants.
