different types of Auto-Tuning.
No.
T1-01
Setting 0: Rotational Auto-Tuning
Setting 1: Stationary Auto-Tuning 1
Setting 2: Stationary Auto-Tuning for Line-to-Line Resistance
Setting 3: Rotational Auto-Tuning for V/f Control
Setting 4: Stationary Auto-Tuning 2
Setting 5: Stationary Auto-Tuning 3
Setting 8: Inertia Tuning
Setting 9: ASR Gain Auto-Tuning
Note: 1. Stationary Auto-Tuning 3 is not available in models CIMR-A4A0930 and 4A1200.
2. Inertia Tuning and ASR Gain Auto-Tuning might not be available if gears are between the machine and the motor shaft.

T1-02: Motor Rated Power
Sets the motor rated power according to the motor nameplate value.
No.
T1-02

T1-03: Motor Rated Voltage (T1-01 = 0, 1, 3, 4, 5)
Sets the motor rated voltage according to the motor nameplate value. If the motor to be operated above its base speed,
enter the voltage at base speed here.
For better control precision around rated speed when using a vector control mode, it can be helpful to enter the no-load
voltage for the motor here. The motor's "no-load voltage" refers to the voltage needed to operate the motor under no-load
conditions at rated speed. The no-load voltage can usually be found in the motor test report available from the
manufacturer. If no data is available, enter approximately 90% of the rated voltage printed on the motor nameplate. Note
that this might increase the output current reducing the overload margin.
No.
T1-03
<1> Values shown here are for 200 V class drives. Double values when using a 400 V class unit.

T1-04: Motor Rated Current
Sets the motor rated current according to the motor nameplate value. For optimal performance in OLV or CLV, the motor
rated current should be between 50 and 100% of the drive rated current. Enter the current at the motor base speed.
No.
T1-04

T1-05: Motor Base Frequency (T1-01 = 0, 1, 2, 4, 5)
Sets the motor rated frequency according to the motor nameplate value. If a motor with an extended speed range is used
or the motor is used in the field weakening area, enter the maximum frequency to E1-04 (E3-04 for motor 2) after
Auto-Tuning is complete.
