12.11 T: AUTOTUNING
SIEPYEUOQ2A01A AC Drive Q2A Technical Manual 827
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. 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.
90% of T1-03
(400 V Class: 0.0 - 510.0
V)
◆ T2: PM MOTOR
T2 parameters set the Auto-Tuning input data for PM motor tuning.
Note:
The drive automatically sets these PM motor parameters:
• E1-xx [E1: V/F PARAMETER MOTOR 1]
• E5-xx [E5: PM MOTOR SETTINGS]
• F1-xx [F1: ENCODER] (CLVonly)
■ T2-01 PM AutoTune Mode Select
No.
(Hex.)
Name Description
Default
(Range)
T2-01
(0750)
PM AutoTune Mode Select
Sets the type of Auto-Tuning for PM motors.
0
(Determined by A1-02)
Note:
For specialized motors, Rotational (Ld, Lq, R, back-EMF) tuning is recommended. Rotational Auto-Tuning rotates the motor to measure
the actual induction voltage constants for more accurate control than Stationary Auto-Tuning.

■ T2-02 PMMot Code Selection
No.
(Hex.)
Name Description
Default
(Range)
T2-02
(0751)
PMMot Code Selection
Sets the PM motor code for drives operating SMRA, SSR1, or SST4-series Yaskawa PM motors.
Determined by A1-02 and
o2-04
(0000 - FFFF)
Enter the motor code in T2-02 to automatically set parameters T2-03 to T2-14. When you are operating a
specialized motor or a non-Yaskawa motor designed, set T2-02 = 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.
■ T2-03 PMMot Motor Type
No.
(Hex.)
Name Description
Default
(Range)
T2-03
(0752)
PMMot Motor Type
Sets the type of PM motor the drive will operate.
