5.11 Auto-TuningAuto-Tuning automatically sets and tunes parameters required for motor operation.u Types of Auto-TuningThere are three types of Auto-Tuning. Refer to Auto-Tuning Selection on page 92 to select the best type of Auto-Tuning for the application.Type Setting Application Conditions and Benefits Control ModeRotational Auto-Tuning for V/f Control T1-01 = 3 Assumes the motor can rotate during the Auto-Tuning process.Improves torque compensation, slip compensation, energy savings, and speed searchperformance. V/f ControlRotational Auto-Tuning forOLV Control T1-01 = 0 Assumes the motor can rotate during the Auto-Tuning processAchieves high-performance motor control Open Loop Vector ControlStationary Auto-Tuning for V/f and OLV Control Line-to-Line Resistance Only T1-01 = 2For use when the motor cable exceeds 50 mThe motor cable length has been modified after Auto-Tuning has been previouslyperformedWhen motor capacity and drive capacity differV/f Control, Open Loop Vector ControlNote: Auto-Tuning cannot be performed on permanent magnet motors (IPM, SPM, etc.).u Auto-Tuning SelectionV/f RotationalAuto-Tuning(T1-01 = 3)StationaryAuto-Tuningfor Terminal Resistance Only(T1-01 = 2)RotationalAuto-Tuning(T1-01 = 0)Select V/f ControlMode (A1-02 = “0”)for the drive.Run the motor without the load.Connect the load and run the motor.Verify system operates as required.Is the cablebetween the motorand drive longerthan 50 m?YES NO NOYESNOYESYESAuto-Tuning finished.NOTICE: Auto-Tuning witha connected load is possible,but may result in less thanoptimum performance.Note: Manually set parameterswhen OLV control is needed.STARTSelect a V/f patternE1-03Open Loop VectorA1-02 = 2Select the Motor Control Mode A1-02Can the load bedisconnected fromthe motor?Will the applicationallow motor rotationfor Auto-Tuning?NOPM Open LoopVector ControlA1-02 = 5Is the totalconnected loadexpected to be lessthan 30% of the motorrating?V/f ControlA1-02 = 0Figure 5.75u Before Auto-Tuning the DriveCheck the items below before Auto-Tuning the drive:5.11 Auto-Tuning210 YASKAWA ELECTRIC SIEP C710606 18A YASKAWA AC Drive – V1000 Technical Manual (Preliminary)
