*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 = V/f Control] .
*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 [Mot Rated Slip] and E2-03 [Mot No-Load Current] .
*4 Input this value when T1-10 [Motor Rated Slip Frequency] = 0 Hz .

Auto-Tuning for PM Motors
This section gives information about Auto-Tuning for PM motors. Auto-Tuning sets motor parameters E1-xx and
E5-xx .

Manual Entry w/ Motor
Data Sheet
T2-01 = 0
• When the information from the motor test report or motor nameplate is available.
• Rotational/Stationary Auto-Tuning that energizes the motor is not done. Manually
input the necessary motor parameters.

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.

T2-01 = 2
• After Auto-Tuning, the wiring distance between the drive and motor changed by 50 m
(164 ft) or more.
•
When the motor output and drive capacity are different.

T2-01 = 4
•
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 can rotate freely while Auto-
Tuning.
• The drive will automatically set the values measured during Auto-Tuning to the motor
parameters.

High Frequency
Injection
T2-01 = 5
• Automatically sets the control parameters that are necessary to set n8-35 = 2
[InitRotorPos Selection = ] or n8-57 = 1 [High-Freq Injection = Enabled] .
•
Applicable to IPM motors only.
•
Do Auto-Tuning with the motor connected to the drive.
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.

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