T2-01 = 0
• When the information from the motor
test report or motor nameplate is not
available.
• Rotational/Stationary Auto-Tuning that
energizes the motor is not done.
Manually input the necessary motor
parameters.
x x x
PM Stationary Auto-
Tuning
T2-01 = 1
• When the information from the motor
test report or motor nameplate is not
available.
Note:
With Stationary Auto-Tuning, the
energized drive stays stopped for
approximately 1 minute. During this
time, the drive automatically measures
the necessary motor parameters.

PM Stationary Auto-
Tuning for Stator
Resistance
T2-01 = 2
• After Auto-Tuning, the wiring distance
between the drive and motor changed by
50 m or more.
• When the motor output and drive
capacity are different.
x x x
Z Pulse Offset Tuning T2-01 = 3
• When you do not know the encoder Z-
pulse offset.
• When the encoder was replaced
• If you have compensated for the
deviation from Z phase (Δθ).
Note:
The motor will rotate slowly while the
drive measures the encoder base
position.

PM Rotational Auto-
Tuning
T2-01 = 4
• When the information from the motor
test report or motor nameplate is
available.
• When you can decouple the motor and
load the motor can rotate freely while
Auto-Tuning.
Values measured during Auto-Tuning
are automatically set to the motor
parameters.

■ Input Data for PM Motor Auto-Tuning
To do Auto-Tuning, input data for the items in Table 3.9 and Table 3.10 that have an "x". Before starting Auto-
Tuning, prepare the motor test report or record the information on the motor nameplate as a reference.
