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.
x
PM Stationary Auto-Tuning
T2-01 = 1
When the information from the motor test report or motor nameplate is not available.
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 (164 ft) or more.
When the motor output and drive capacity are different.
Rotational (Ld, Lq, R, back-EMF)
T2-01 = 4
When you can decouple the motor and load and the motor can rotate freely while Auto-Tuning.
Values measured during Auto-Tuning are automatically set to the motor parameters.
High Frequency Injection
T2-01 = 5
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.
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.
To do Auto-Tuning, input data for the items in Table 2 and Table 3 that have an "x". Before you start Auto-Tuning, prepare the motor test report or record the information from the motor nameplate as a reference.
