Repeat Steps 1 through 5 to set the following parameters:
• T1-03, Motor Rated Voltage
• T1-04, Motor Rated Current
6 • T1-05, Motor Base Frequency
• T1-06, Number of Motor Poles
• T1-07, Motor Base Speed
• T1-08 (PG Number of Pulses Per Revolution)
Note: To execute Stationary Auto-Tuning for Line-to-Line Resistance, set parameters T1-02 and T1-04.

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
drive malfunction. Ensure the motor can freely spin before beginning Auto-Tuning.
NOTICE: Do not run the Rotational Auto-Tuning for load-connected motor. When the Rotational Auto-Tuning is performed for load-
connected motor, the motor parameter could not be calculated accurately and the motor could run unusually. Disconnect the
motor from the load.
Enter the required data from the motor nameplate. Press

◆ Parameter Settings during Auto-Tuning for Induction Motors

The T1- parameters are used to set the Auto-Tuning input data.
Note: For motors that are to be operated in the field weakening range, first perform the Auto-Tuning with the base data. After Auto-
Tuning is complete, change the maximum frequency E1-04 to the desired value.
