[Selection 2: Setting vector control and auto-tuning independently]
Set vector control, automatic torque boost, energy saving and auto-tuning individually.
After setting

Set
f400 to 2 before the start of operation. Auto-tuning is performed at the start of the motor and set

● Precautions on auto-tuning
(1) Conduct auto-tuning after the motor has been connected properly 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 inverter trips with the display
of
etn1
and no constants are set for that motor. Set
f400
to
0
and perform manual tuning
with selection 4.
(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. Insufficient
motor torque while tuning may cause machine stalling/falling.
(6) If auto-tuning is impossible or an " etn1 " auto-tuning error is displayed, perform manual tuning
with selection 4.
[Selection 3: Setting vector control and motor constant automatically]
After setting vl , vlv , f405 , f415 and f417 , motor constants calculated automatically.
f402
,
f412
and
f416
are set automatically.
Set the motor constant parameter
f400
to
4
(auto calculation)
Set f400 = 5 when auto-tuning is executed after setting motor constants automatically.
