4 Start-Up Programming & OperationYASKAWA ELECTRIC TOEP C710616 21C YASKAWA AC Drive - A1000 Quick Start Guide 91Start-Up Programming& Operation4◆ Auto-Tuning■ Types of Auto-TuningThe drive offers different types of Auto-Tuning for induction motors and permanent magnet motors. The type of Auto-Tuning used differs further based on the control mode and other operating conditions. Refer to the tables below to selectthe type of Auto-Tuning that bests suits the application. Directions on how to execute Auto-Tuning are listed in Start-UpFlowcharts on page 58.Note: The drive will only show Auto-Tuning parameters that are valid for the control mode that has been set to A1-02. If the controlmode is for an induction motor, the Auto-Tuning parameters for PM motors will not be available. If the control mode is for a PMmotor, the Auto-Tuning parameters for induction motors will not be available. Inertia Tuning and ASR Gain Tuning parametersand setting options will be visible only when the drive is set for operation with Closed Loop Vector or CLV/PM.Auto-Tuning for Induction MotorsThis feature automatically sets the V/f pattern and motor parameters E1- and E2- (E3-, E4- for motor 2)for an induction motor. In Closed Loop Vector, some F1- parameters for speed feedback detection are also set up.Table 42 Types of Auto-Tuning for Induction MotorsTable 43 lists the data that must be entered for Auto-Tuning. Make sure this 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 themotor manufacturer. Also refer to page 60 and 61 for details on Auto-Tuning process and selections.Type Setting Application Conditions and Benefits Control ModeV/f V/f w/PG OLV CLVRotational Auto-Tuning T1-01 = 0• Motor can be decoupled from the load and rotate freelywhile Auto-Tuning is performed.• Motor and load can not be decoupled but the motor loadis below 30%.• Rotational Auto-Tuning gives the most accurate results,and is therefore highly recommended if possible.N/A N/A YES YESStationary Auto-Tuning1 T1-01 = 1• Motor and load can not be decoupled and the load ishigher than 30%.• A motor test report listing motor data is not available.• Automatically calculates motor parameters needed forvector control.N/A N/A YES YESStationary Auto-Tuning2 T1-01 = 4• Motor and load can not be decoupled and the load ishigher than 30%.• A motor test report is available. Once the no-load currentand the rated slip have been entered, the drive calculatesand sets all other motor-related parameters.N/A N/A YES YESStationary Auto-Tuningfor Line-to-LineResistanceT1-01 = 2• The drive is used in V/f Control and other Auto-Tuningselections 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 modes unlessthe motor cable has changed.YES YES YES YESRotational Auto-Tuningfor V/f Control T1-01 = 3• Recommended for applications using Speed EstimationSpeed Search or using the Energy Saving function in V/fControl.• Assumes motor can rotate while Auto-Tuning isexecuted. Increases accuracy for certain functions liketorque compensation, slip compensation, Energy Saving,and Speed Search.YES YES N/A N/A
