PM Rotational Auto-Tuning 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 the
motor can rotate freely while Auto-Tuning.
• Values measured during Auto-Tuning are
automatically set to the motor parameters.

T2-01 = 5
• Automatically determines the control parameters
required 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.
• Perform tuning with the motor connected to the
drive.
Note:
When you want to set n8-35 = 1 or n8-57 = 1,
perform High Frequency Injection Auto-Tuning.
Configure the drive with the data from the motor
nameplate before performing High Frequency
Injection Auto-Tuning. High Frequency Injection
Auto-Tuning automatically makes adjustments
while it is stopped but still energized.

■ Input Data for PM Motor Auto-Tuning
To do Auto-Tuning, input data for the items in Table 4.9 and Table 4.10 that have an "x". Before starting Auto-
Tuning, prepare the motor test report or record the information on the motor nameplate as a reference.
