[Selection 1: Setting by parameter setting macro torque boost]
This is the easiest of the available methods. It conducts vector control and auto-tuning at the same time.
Be sure to set the motor for  ,  ,  ,  ,  .
Set  to 
(Automatic torque boost + auto-tuning)
Set  to 
(Vector control + auto-tuning).
Set  to 
(Energy-saving + auto-tuning)
See Section 5.4 for details of the setting method.
[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)
6
[Parameter setting]

Set f400 to 2 to before the start of operation. Tuning is performed at the start of the motor.
Title Function
0: Auto-tuning disabled (use of internal parameters)
Auto-tuning 1: Initialization of  (reset to 0)
2: Auto-tuning executed (after execution: 0)
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.
