11 Auto-Tuning
Note:
Do Stationary Auto-Tuning if you cannot do Rotational Auto-Tuning. There can be large differences between
the measured results and the motor characteristics when Auto-Tuning is complete. Examine the parameters for
the measured motor characteristics after you do Stationary Auto-Tuning.

Application Conditions and Benefits
Settings
• When you can decouple the motor and
load the motor can rotate freely while
Auto-Tuning.
• When operating motors that have fixed
output characteristics.
T1-01 = 0
• When it is necessary to use motors that
have high-precision control.
• When you cannot decouple the motor
and load, but the motor load is less than
30%.
• When you cannot decouple the motor
and load.
• When the motor load is more than 30%.
• When the information from the motor
test report or motor nameplate is not
available.
With Stationary Auto-Tuning, the
T1-01 = 1
energized drive stays stopped for
approximately 1 minute. During this
time, the drive automatically measures
the necessary motor parameters.
• When you operate the motor with less
than 30% load after Auto-Tuning.
Set T1-12 = 1 [Test Mode Selection =
Yes] to do a test run after Auto-Tuning.
• After Auto-Tuning, the wiring distance
between the drive and motor changed by
50 m or more.
• When the wiring distance is 50 m or
T1-01 = 2
more in the V/f Control mode.
• When the motor output and drive
capacity are different.
