Auto-Tuning for Induction Motors
This feature automatically sets the V/f pattern and motor parameters E1-
oo
and E2-

Stationary 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.
• Perform when entering motor data manually while using motor cables
longer than 50 m.
• Drive and motor capacities differ.
• Tunes the drive after the cable between the drive and motor 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 unless the motor cable
has changed.

Rotational Auto-Tuning for
V/f Control
T1-01 = 3
• Recommended for applications using Speed Estimation Speed Search
or using the Energy Saving function in V/f Control.
• Assumes motor can rotate while Auto-Tuning is executed. Increases
accuracy for certain functions like torque compensation, slip
compensation, Energy Saving, and Speed Search.

T1-01 = 4
• Motor and load cannot be decoupled and the load is higher than 30%.
• A motor test report is available. After entering the no-load current and
the rated slip, the drive calculates and sets all other motor-related
parameters.

The necessary information is usually listed on the motor nameplate or in the motor test report provided by the motor
manufacturer.
