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
(0BDC)
Note:
To get the same qualities as a Yaskawa 1000-series drive or previous models, set this parameter = T1-03 [Motor Rated Voltage] value.

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 [PM Motor Settings]
• F1-xx [PG Speed Control Card (Encoder)] (CLV only)

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)
4 : Rotational (Ld, Lq, R, back-EMF)

V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
Sets the no-load voltage of the motor. If no-load voltage is necessary at
rated speed for the motor test report, set the voltage in this parameter. If the
motor test report is not available, do not change this parameter.
V/f CL-V/f OLV CLV AOLV
Sets the type of Auto-Tuning for PM motors.
