n Auto-Tuning for Permanent Magnet MotorsAutomatically sets the V/f pattern and motor parameters E1-oo and E5-oo when a PM motor is used.Table 4.20 Types of Auto-Tuning for Permanent Magnet MotorsType Setting Application Conditions and Benefits Control ModeOLV/PMPM Motor ParameterSettings T2-01 = 0 • Motor does not rotate during Auto-Tuning.• Motor test report or motor data similar to Table 4.21 are available. YESTable 4.21 lists the data that must be entered for Auto-Tuning. Make sure the data is available before starting Auto-Tuning.The necessary information is usually listed on the motor nameplate or in the motor test report provided by the motormanufacturer. Also refer to page 116 for details on the Auto-Tuning process and selection.Table 4.21 Auto-Tuning Input DataInput Value Input Parameter UnitTuning Type (T2-01)0Motor ParameterSettingsControl Mode A1-02 – 5Motor Type T2-03 – –Motor Rated Power T2-04 kW YESMotor Rated Voltage T2-05 Vac YESMotor Rated Current T2-06 A YESMotor Rated Frequency T2-07 Hz YESNumber of Motor Poles T2-08 – YESStator Single-phase Resistance T2-10 Ω YESd-Axis Inductance T2-11 mH YESq-Axis Inductance T2-12 mH YESInduced Voltage Constant Unit Selection <1> T2-13 mVs/rad (elec.)

Make sure this data is availablebefore Auto-Tuning the drive.• For best performance, the drive input supply voltage must be at least equal to or greater than the motor rated voltage.Note: Better performance is possible when using a motor with a base voltage that is lower than the input supply voltage (60 V for 600 V classmodels). This is particularly important when operating the motor above 90% of base speed, where high torque precision is required.• To cancel Auto-Tuning, press the OFF key on the HOA keypad.• When using a motor contactor, make sure it is closed throughout the Auto-Tuning process.Table 4.22 Auto-Tuning Input DataMotor Type Auto-Tuning Type Digital Input Digital OutputInductionMotorStationary Auto-Tuning for Line-to-Line Resistance Digital input functionsare disabled.Maintains the status at the start of Auto-TuningRotational Auto-Tuning for V/f Control Functions the same as during normal operationPM Motor PM Motor Parameter Settings Digital output functions are disabled.4.8 Auto-TuningYASKAWA TOEP YAIZ1U 03B YASKAWA AC Drive – Z1000 User Manual 1374 Start-Up Programming& Operation
