T1-12: Test Mode Selection
No.
(Hex.)
Name Description
Default
(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
(0, 1)
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

(Range)
T1-13
(0BDC)
No-load voltage
Sets the no-load voltage of the motor. If you know the no-load voltage at the rated speed in a test
report, set that voltage value. If you do not know the no-load voltage, do not change from the initial
value.
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 models, set this parameter = T1-03 [Motor Rated Voltage] value.
•
The default value is different for different models.
–
2004 - 2008, 4002 - 4004: T1-03 × 0.85
– 2010 - 2415, 4005 - 4302: T1-03 × 0.90
– 4371- 4720: 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]

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.
