2.12 T: Auto-Tuning
452 YASKAWA TOEPYAIGA5002A GA500 DRIVE PROGRAMMING
After Auto-Tuning, the drive automatically sets E2-02 [Motor Rated Slip] and E2-03 [Motor No-Load Current] when
you operate the motor for the first time in Drive Mode.
Note:
After Auto-Tuning is complete and you set the drive to Drive Mode, operate the motor in these conditions:
• Make sure that you connect all wiring between the drive and motor
• Make sure that a mechanical brake on the motor shaft is not locked
• Keep the motor-load ratio at 30%
• Hold constant speed for longer than 1 second at a minimum of 30% of the speed set in E1-06 [Base Frequency] (the default setting is the
same as the maximum frequency).
■ T1-13: No-load voltage
No.
(Hex.)
Name Description
Default
(Range)
T1-13
(0BDC)
No-load voltage
Sets the no-load voltage of the motor. When the no-load voltage at rated speed is available, for
example on the motor test report, set the voltage in this parameter. If the no-load voltage is not
available, do not change this parameter.
T1-03 × 0.9
(200 V Class: 0.0 - 255.0 V,
400 V Class: 0.0 - 510.0 V)
Note:
• To get the same qualities as a Yaskawa 1000-series drive or previous series drive, set this parameter = T1-03 [Motor Rated Voltage].
• The default setting is different for different models.
–B001 - B006, 2001 - 2008, 4001 - 4004: T1-03 × 0.85
–B010 - B018, 2010 - 2082, 4005 - 4060: T1-03 × 0.90
◆ T2: PM Motor Auto-Tuning
T2 parameters set the Auto-Tuning input data for PM motor tuning.
Note:
The drive automatically sets these PM motor parameters:
• E1-xx [V/f Pattern for Motor 1]
• E5-xx [V/f Pattern for Motor 1]
■ T2-01: PM Auto-Tuning Selection
No.

T2-01
(0750)
PM Auto-Tuning Selection
Sets the type of Auto-Tuning for PM motors.
0
(Determined by A1-02)
Note:
Yaskawa recommends PM Rotational Auto-Tuning for specialized motors. Rotational Auto-Tuning rotates the motor to measure the actual
induction voltage constants for more accurate control than Stationary Auto-Tuning.
0 : Manual Entry w/ Motor Data Sheet
1 : Stationary (Ld, Lq, R)
2 : Stationary (R Only)
4 : Rotational (Ld, Lq, R, back-EMF)
5 : High Frequency Injection
■ T2-02: PM Motor Code Selection
No.

T2-02
(0751)
PM Motor Code Selection
If the drive is operating an SMRD, SMRA, or SSR1 series Yaskawa PM motor, enter the PM motor
code in to align with the rotation speed and motor output.
FFFF
(0000 - FFFF)
Enter the motor code to automatically set parameters T2-03 to T2-14. When you are operating a specialized motor or a
non-Yaskawa motor, set T2-02 = FFFF and enter the data from the motor nameplate or the motor test report.
