Parameter Settings During Induction Motor Auto-Tuning: T1 - YASKAWA L1000A Technical Manual

4.5 Auto-Tuning
1.
After entering the data listed on the motor nameplate, press
Press to activate Auto-Tuning. The drive begins by injecting current into the motor for about 1 min,
and then starts to rotate the motor.
2.
Note: The first digit on the display indicates which motor is undergoing Auto-Tuning (motor 1 or motor 2). The
second digit indicates the type of Auto-Tuning being performed.
3. Auto-Tuning finishes in approximately one to two minutes.

◆ Parameter Settings during Induction Motor Auto-Tuning: T1

The T1- parameters are used to 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.

T1-03: Motor Rated Voltage
■
Sets the motor rated voltage according to the motor nameplate value. Enter the motor voltage at base speed here if the
motor is operating above base speed.
Enter the voltage needed to operate the motor under no-load conditions at rated speed to T1-03 for better control precision
around rated speed when using a vector control mode. The no-load voltage can usually be found in the motor test report
available from the manufacturer. If the motor test report is not available, enter approximately 90% of the rated voltage
printed on the motor nameplate. This may increase the output current and reduce the overload margin.
