■ T2: PM Motor Auto-Tuning
T1-08
(708H)
PG Number of Pulses Per
Revolution
Set the number of pulses per revolution for the PG being used (pulse generator or encoder).
Default: 1024 ppr
Min: 0 ppr
Max: 60000 ppr
116
T1-09
(709H)
Motor No-Load Current
(Stationary Auto-Tuning)
Sets the no-load current for the motor.
After setting the motor capacity to T1-02 and the motor rated current to T1-04, this parameter
will automatically display the no-load current for a standard 4 pole Yaskawa motor. Enter the
no-load current as indicated on the motor test report.
Default: –
Min: 0 A
Max: T1-04
116
T1-10
(70AH)
Motor Rated Slip
(Stationary Auto-Tuning)
Sets the motor rated slip.
After setting the motor capacity to T1-02, this parameter will automatically display the motor
slip for a standard 4 pole Yaskawa motor. Enter the motor slip as indicated on the motor test
report.
Default: –
Min: 0.00 Hz
Max: 20.00 Hz

T1-11
(70BH)
Motor Iron Loss
Sets the iron loss for determining the Energy Saving coefficient.
The value is set to E2-10 (motor iron loss) set when the power is cycled. If T1-02 is changed, a
default value appropriate for the motor capacity that was entered will appear.
Default: 14 W
<38>
Min: 0 W
Max: 65535 W
116
<6> Default setting value varies by the drive model (o2-04).
<10> Default setting is determined by the control mode (A1-02).
<18> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<37> The availability of certain Auto-Tuning methods depends on the control mode selected for the drive.
<38> Default setting value differs depending on the motor code value and motor parameter settings.

PM Motor Auto-Tuning Mode
Selection
0: PM Motor Parameter Settings
1: PM Stationary Auto-Tuning
2: PM Stationary Auto-Tuning for Stator Resistance
3: Z Pulse Offset Tuning
8: Inertia Tuning
9: ASR Gain Auto-Tuning
Prior to executing Inertia Tuning or ASR Gain Auto-Tuning, be sure to take the following steps:
• perform Auto-Tuning for motor data (T2-01 = 0, 1, or 2) or set the motor code to E5-01.
• verify all motor data entered to the drive with the motor nameplate or the motor test report.
Default: 0
Min: 0
Max: 3, 8, 9

T2-02
(751H)
PM Motor Code Selection
Enter the motor code when using a Yaskawa PM motor. Once the motor code is entered, the
drive automatically sets parameters T2-03 through T2-14. When using a motor that is not
supported motor code or a non-Yaskawa motor, set FFFF here and then adjust the other T2
parameters according the motor nameplate or the motor test report.
Default:
<16>
Min: 0000
Max: FFFF
