Input Data for Auto-Tuning

The T1-oo parameters are used to set the Auto-Tuning input data.
Note: 1. Cycling power to the drive will reset any values set during the Auto-Tuning process to factory defaults.
2. For motors that are to be operated in the field weakening range, first perform the Auto-Tuning with the base data, i.e. the frequency
at which the motor is operating with its rated voltage (base frequency). After Auto-Tuning is complete, change the maximum
frequency E1-04 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.
T1-00
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: Tuning Mode Selection
Sets the type of Auto-Tuning to be used.
Auto-Tuning.
No.
T1-01
Setting 0: Rotating Auto-Tuning for Open Loop Vector Control
Setting 2: Stationary Auto-Tuning for Line-to-Line Resistance
Setting 3: Rotating Auto-Tuning for V/f Control
n T1-02: Motor Rated Power
Used to set the motor rated power according to the motor nameplate value. For optimal performance, the motor rated power
should be between 50 and 100% of the drive rating.
No.
T1-02
<1> The setting range differs based on drive software version.
PRG: 1016 and later: 0.03 to 650.00 kW
PRG: 1015 and earlier: 0.00 to 650.00 kW
n T1-03: Motor Rated Voltage (T1-01 = 0 or 3)
Used to set the motor rated voltage according to the motor nameplate value. If the motor is used above its base speed, enter
the voltage at base speed here.
For higher tuning precision and better control performance, enter the motor no-load voltage here if known. The motor no-
load voltage is referred as to the voltage needed to operate the motor under no-load condition at its rated speed. Refer to
the motor data sheet.
No.
T1-03
<1> Values shown here are for 200 V class drives. Double values when using a 400 V class drive.
n
T1-04: Motor Rated Current
Used to set the motor rated current according to the motor nameplate value. For optimal performance in OLV, the motor
rated current should be between 50 and 100% of the drive rating. Enter the current at the motor base speed.
No.
