T2: Pm Motor Auto-Tuning - YASKAWA GA700 Series Technical Manual

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.
Name
(Hex.)
T1-13 No-Load Voltage
(0BDC)
Note:
To get the same qualities as a Yaskawa 1000-series drive or previous series drive, set this parameter = T1-03 [Motor Rated Voltage].
◆

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
No.
Name
(Hex.)
T2-01 PM Auto-Tuning Selection
(0750)
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)
5 : High Frequency Injection
■
T2-02: PM Motor Code Selection
No.
Name
(Hex.)
T2-02 PM Motor Code Selection
(0751)
Enter the motor code in this parameter to automatically set parameters T2-03 to T2-14. When you are operating a
specialized motor or a non-Yaskawa motor, set this parameter to FFFF and enter the data from the motor
nameplate or the motor test report.
You can only enter the permitted PM motor codes. Different drive control methods will accept different PM motor
codes.

V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
Sets the type of Auto-Tuning for PM motors.
V/f CL-V/f OLV CLV AOLV
Enter the PM motor code as specified by the rotation speed and motor output.
