■ T1-12: Test Mode Selection
No.
(Hex.)
Name Description

(Range)
T1-12
(0BDB)
Test Mode Selection
Sets the function to enable Test Mode after Stationary Auto-Tuning. When you can operate the motor
with a light load attached after Stationary Auto-Tuning is complete, enable this parameter.

0 : No
1 : Yes
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

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 × 0.85
(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.
–2004 to 2006, 4002 to 4004: T1-03 × 0.85
–2010 to 2415, 4005 to 4250, T103 to T250: T1-03 × 0.90
–4296 to 4720, T296 to T720: T1-03 × 0.95
◆ 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]
• F1-xx [Encoder Option Setup]
Only when A1-02 = 7 [Control Method Selection = PM Closed Loop Vector]
■ T2-01: PM Auto-Tuning Selection

PM Auto-Tuning Selection
Sets the type of Auto-Tuning for PM motors.
0
(Determined by A1-02)
Note:
Yaskawa recommends Rotational (Ld, Lq, R, back-EMF) 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)
3 : Z-Pulse Offset (Pole Position)
