*1 Shows 0 Hz as the default value. If you do not know the Motor Rated Slip Frequency, keep the setting at 0 Hz.
*2 Input this value when A1-02 = 0 [Control Method Selection = V/f].
*3 If T1-12 = 1 [Test Mode Selection = Yes], when you run the motor in Drive Mode for the first time after Auto-Tuning, the drive will
automatically set E2-02 [Motor Rated Slip] and E2-03 [Motor No-Load Current].
*4 Input this value when T1-10 [Motor Rated Slip Frequency] = 0 Hz.
*5 Set the same value to No-Load Voltage as T1-03 [Motor Rated Voltage] to get the same characteristics using Yaskawa 1000-Series drives
or other legacy models.

Input Data for PM Motor Auto-Tuning
To do Auto-Tuning, input data for the items in
Tuning, prepare the motor test report or record the information from the motor nameplate as a reference.

Table 6.7 Auto-Tuning for PM Motors
Parameter Settings Application Conditions and Benefits
• When the information from the motor test report or motor
nameplate is available.
T2-01 = 0
• Rotational/Stationary Auto-Tuning that energizes the motor is
not done. Manually input the necessary motor parameters.
• When the information from the motor test report or motor
nameplate is not available.
Note:
T2-01 = 1
With Stationary Auto-Tuning, the energized drive stays
stopped for approximately 1 minute. During this time, the
drive automatically measures the necessary motor
parameters.
• After Auto-Tuning, the wiring distance between the drive and
motor changed by 50 m (164 ft) or more.
T2-01 = 2
• When the motor output and drive capacity are different.
• When the information from the motor test report or motor
nameplate is not available.
• When you can decouple the motor and load and the motor
T2-01 = 4
can rotate freely while Auto-Tuning.
• Values measured during Auto-Tuning are automatically set to
the motor parameters.
• Automatically sets the control parameters that are necessary
to set n8-35 = 1 [Initial Pole Detection Method = High
Frequency Injection] or n8-57 = 1 [HFI Overlap Selection =
Enabled].
• Applicable to IPM motors only.
• Do Auto-Tuning with the motor connected to the drive.
T2-01 = 5
Note:
When you set n8-35 = 1 or n8-57 = 1, do High Frequency
Injection Auto-Tuning. Set the data on the motor nameplate
to the drive before you do High Frequency Injection Auto-
Tuning. In High Frequency Injection Auto-Tuning, the drive
energizes the stopped motor and automatically adjusts the
parameters.
