1.11 T: Motor Tuning
Auto-Tuning automatically sets and tunes parameters required for optimal motor performance.
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
T1-00: Motor 1/Motor 2 Selection
Selects the motor to be tuned when motor 1/2 switching is enabled (i.e., a digital input is set for function H1-oo = 16). This
parameter is not displayed if motor 1/2 switching is disabled.
No. Name Setting Range Default
T1-00 Motor 1/Motor 2 Selection 1, 2 1
Setting 1: Motor 1
Auto-Tuning automatically sets parameters E1-oo and E2-oo for motor 1.
Setting 2: Motor 2
Auto-Tuning automatically sets parameters E3-oo and E4-oo for motor 2. Make sure that motor 2 is connected to the drive
for Auto-Tuning.
n
T1-01: Auto-Tuning Mode Selection
Sets the type of Auto-Tuning to be used.

T1-02: Motor Rated Power
Sets the motor rated power according to the motor nameplate value.
No. Name Setting Range Default
T1-02 Motor Rated Power 0.00 to 650.00 kW
Determined by
o2-04 and C6-01
n
T1-03: Motor Rated Voltage
Sets the motor rated voltage according to the motor nameplate value. Enter the voltage 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.
