Table 4.8 lists the data that must be entered for Auto-Tuning. Make sure the data is available before starting Auto-Tuning.
The information needed is usually listed on the motor nameplate or in the motor test report provided by the motor
manufacturer. Also refer to page

Setting
• Use if a motor test report is available
T2-01 = 0 • Input motor data from the motor test report. Convert data into the correct unit before inputting data if necessary.
• Motor does not rotate during Auto-Tuning
• Use if a motor test report is not available
T2-01 = 1 • Input motor data from the motor name plate. Make sure to convert data into the correct units. The drive automatically calculates the
motor data.
• Tunes stator resistance only.
T2-01 = 2
• Should be performed if the motor cabling has changed.
• Use if a motor test is not available
• Tunes the Motor Induction Voltage only
T2-01 = 11
• Should be performed after Motor data are set and the encoder offset is adjusted.
• The motor must be uncoupled from the mechanical system (remove ropes).
