4.8 Auto-Tuningu Types of Auto-TuningThe drive offers different types of Auto-Tuning for induction motors and permanent magnet motors. The type of Auto-Tuningused differs further based on the control mode and other operating conditions. Refer to the tables below to select the type ofAuto-Tuning that bests suits the application. Refer to Start-Up Flowcharts on page 113 for directions on executing Auto-Tuning.Note: The drive will only show Auto-Tuning parameters that are valid for the control mode that has been set in A1-02. If the control mode is foran induction motor, the Auto-Tuning parameters for PM motors will not be available.n Auto-Tuning for Induction MotorsThis feature automatically sets the V/f pattern and motor parameters E1-oo and E2-oo for an induction motor.Table 4.18 Types of Auto-Tuning for Induction MotorsType Setting Application Conditions and BenefitsControlModeV/fStationary Auto-Tuning for Line-to-Line Resistance T1-01 = 2• The drive is used in V/f Control and other Auto-Tuning selections are notpossible.• Drive and motor capacities differ.• Tunes the drive after the cable between the drive and motor has been replacedwith a cable over 50 m long. Assumes Auto-Tuning has already beenperformed.• Should not be used for any vector control modes unless the motor cable haschanged.YESRotational Auto-Tuning for V/fControl T1-01 = 3• Recommended for applications using Speed Estimation Speed Search or usingthe Energy Saving function in V/f Control.• Assumes motor can rotate while Auto-Tuning is executed. Increases accuracyfor certain functions like torque compensation, slip compensation, EnergySaving, and Speed Search.YESTable 4.19 lists the data that must be entered for Auto-Tuning. Make sure this 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 115 for details on Auto-Tuning processes and selections.Table 4.19 Auto-Tuning Input DataInput Value Input Parameter UnitTuning Type (T1-01)2Line-to-Line Resistance3Rotational forV/f ControlMotor rated power T1-02 kW YES YESMotor rated voltage T1-03 Vac – YESMotor rated current T1-04 A YES YESMotor rated frequency T1-05 Hz – YESNumber of motor poles T1-06 – – YESMotor rated Speed T1-07 r/min – YESMotor iron loss T1-11 W – YES4.8 Auto-Tuning136 YASKAWA TOEP YAIZ1U 03B YASKAWA AC Drive – Z1000 User Manual
