4.7 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 127 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. If the control mode is for a PM motor, the Auto-Tuning parameters for induction motors will not be available. Inertia Tuning and ASR Gain Tuning parameters and setting options will bevisible only when the drive is set for operation with CLV or CLV/PM.n Auto-Tuning for Induction MotorsThis feature automatically sets the V/f pattern and motor parameters E1-oo and E2-oo (E3-oo, E4-oo for motor 2) foran induction motor. Additionally, the feature also sets some F1-oo parameters for speed feedback detection in Closed LoopVector.Table 4.28 Types of Auto-Tuning for Induction MotorsType Setting Application Conditions and BenefitsControl ModeV/f V/f w/PG OLV CLVRotational Auto-Tuning T1-01 = 0• Motor can be decoupled from the load and rotatefreely while Auto-Tuning is performed.• Motor and load cannot be decoupled but the motorload is below 30%.• Rotational Auto-Tuning gives the most accurateresults, and is recommended if possible.– – YES YESStationaryAuto-Tuning 1 T1-01 = 1• Motor and load cannot be decoupled and the load ishigher than 30%.• A motor test report listing motor data is notavailable.• Automatically calculates motor parameters neededfor vector control.– – YES YESStationaryAuto-Tuning 2 T1-01 = 4• Motor and load cannot be decoupled and the load ishigher than 30%.• A motor test report is available. After entering the no-load current and the rated slip, the drive calculatesand sets all other motor-related parameters.– – YES YESStationary Auto-Tuning for Line-to-Line Resistance T1-01 = 2• The drive is used in V/f Control and other Auto-Tuning selections are not possible.• Drive and motor capacities differ.• Tunes the drive after the cable between the drive andmotor has been replaced with a cable over 50 m long.Assumes Auto-Tuning has already been performed.• Should not be used for any vector control modesunless the motor cable has changed.YES YES YES YESRotational Auto-Tuning for V/fControl T1-01 = 3• Recommended for applications using SpeedEstimation Speed Search or using the Energy Savingfunction inV/f Control.• Assumes motor can rotate while Auto-Tuning isexecuted. Increases accuracy for certain functionslike torque compensation, slip compensation, EnergySaving, and Speed Search.YES YES – –StationaryAuto-Tuning 3 T1-01 = 5• A motor test report listing motor data is not available.• Motor can be driven with a normal duty mode afterAuto-Tuning. A trial run is performed after Auto-Tuning to automatically calculate motor parametersneeded for vector control.– – YES YESTable 4.29 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. Refer to Subchart A-1: Simple Motor Setup Using V/f Control on page 129 and Refer to Subchart A-2: HighPerformance Operation Using OLV or CLV on page 130 for details on Auto-Tuning processes and selections.4.7 Auto-Tuning164 YASKAWA ELECTRIC TOEP C710616 41G YASKAWA AC Drive - A1000 Quick Start Guide
