n Starting Auto-Tuning
WARNING! Sudden Movement Hazard. The drive and motor may start unexpectedly during Auto-Tuning, which could result in death or
serious injury. Ensure the area surrounding the drive motor and load are clear before proceeding with Auto-Tuning.
WARNING! Electrical Shock Hazard. High voltage will be supplied to the motor when Stationary Auto-Tuning is performed even with the
motor stopped, which could result in death or serious injury. Do not touch the motor until Auto-Tuning has been completed.
NOTICE: Rotational Auto-Tuning will not function properly if a holding brake is engaged on the load. Failure to comply could result in improper
operation of the drive. Ensure the motor can freely spin before beginning Auto-Tuning.
Enter the required information from the motor nameplate. Press to proceed to the Auto-Tuning start display.
Note: These instructions continue from Step 6 in “Enter Data from the Motor Nameplate”.

u T1: Parameter Settings during Induction Motor Auto-Tuning
The T1-oo parameters set the Auto-Tuning input data for induction motor tuning.
Note: For motors operating in the field weakening range, first perform the Auto-Tuning with the base data. After Auto-Tuning is complete, change
E1-04, Maximum Output Frequency, to the desired value.
n T1-01: Auto-Tuning Mode Selection
Sets the type of Auto-Tuning to be used. Refer to Auto-Tuning for Induction Motors on page 131 for details on the different
types of Auto-Tuning.

Setting 2: Stationary Auto-Tuning for Line-to-Line Resistance
Setting 3: Rotational Auto-Tuning for V/f Control Energy Saving
n T1-02: Motor Rated Power
Sets the motor rated power according to the motor nameplate value.
Note: Use the following formula to convert HP to kW: kW = HP x 0.746.
