128 YASKAWA ELECTRIC TOEP C710687 02B FSDrive-MV1000 Instructions
Setting 1: Motor 1
Auto-Tuning automatically sets parameters E1- and E2- for motor 1.
Setting 2: Motor 2
Auto-Tuning automatically sets parameters E3- and E4- 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. Refer to Types of Auto-Tuning on page 124 for details on the different types of
Auto-Tuning.
Auto-Tuning is not possible when running multiple motors.
Setting 0: Rotational Auto-Tuning
Setting 2: Stationary Auto-Tuning for Line-to-Line Resistance
n T1-02: Motor Rated Capacity
Sets the rated capacity of the motor according to the value on the motor nameplate.
n
T1-03: Motor Rated Voltage (T1-01 = 0)
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.
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 95% of the rated voltage printed on the motor nameplate.
n
T1-04: Motor Rated Current
Sets the motor rated current according to the motor nameplate value. Set the motor rated current between 50% and 100%
of the drive rated current for optimal performance in OLV or CLV. Enter the current at the motor base speed.
n
T1-05: Motor Base Frequency (T1-01 = 0)
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.
