Auto-Tuning

Auto-Tuning uses motor characteristics to automatically set parameters for vector control. Think about the type of
motor and the motor installation environment and select the best Auto-Tuning method.
The keypad will show the messages with prompts to input the necessary parameter information.

Auto-Tuning for Induction Motors

This section gives information about Auto-Tuning for induction motors. Auto-Tuning sets motor parameters E1-xx,
E2-xx.
Note:
Do Stationary Auto-Tuning if you cannot do Rotational Auto-Tuning. There can be large differences between the measured results and the
motor characteristics when Auto-Tuning is complete. Examine the parameters for the measured motor characteristics after you do Stationary
Auto-Tuning.

Input Data for Induction Motor Auto-Tuning
To do Auto-Tuning, input data for the items in
motor test report or record the information on the motor nameplate as a reference.
Input Data
Motor Rated Power
Motor Rated Voltage
Motor Rated Current
Motor Base Frequency
Number of Motor Poles
Motor Base Speed
Motor Iron Loss

Precautions before Auto-Tuning
Examine the topics in this section before you start Auto-Tuning.
■
Prepare for Basic Auto-Tuning
• You must input data from the motor nameplate or motor test report to do Auto-Tuning. Make sure that this data is
available before Auto-Tuning.
• For best performance, make sure that the input supply voltage is equal to or more than the motor rated voltage.

Application Conditions and Benefits
• When you can decouple the motor and load the motor can rotate freely while Auto-
Tuning.
• When operating motors that have fixed output characteristics.
• When it is necessary to use motors that have high-precision control.
• When you cannot decouple the motor and load, but the motor load is less than 30%.
• After Auto-Tuning, the wiring distance between the drive and motor changed by 50
m or more.
• When the wiring distance is 50 m or more in the V/f Control mode.
• When the motor output and drive capacity are different.
