*1 Set the motor code for a Yaskawa PM motor.
*2 Set the motor code to FFFF for a PM motor from a different manufacturer.
*3 Changes when the value set in T2-13 changes.
*4 Input this value when A1-02 = 7 [Control Method Selection = PM Closed Loop Vector Control].

Application Conditions and Benefits
• When the information from the motor test report or
motor nameplate is not available.
• When you can decouple the motor and load the motor
T2-01 = 4
can rotate freely while Auto-Tuning.
• Values measured during Auto-Tuning are
automatically set to the motor parameters.
• 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:
T2-01 = 5
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.
