11.12 T: Auto-Tuning
YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual 803
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. 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.
90% of T1-03
(200 V Class: 0.0 - 255.0 V,
400 V Class: 0.0 - 510.0 V)
Note:
Set this value to the same setting as T1-03 [Motor Rated Voltage] to get the same characteristics using a Yaskawa drive 1000 Drive
Series or earlier models.
◆ T3: ASR and Inertia Tuning
■ T3-00: Control Loop Tuning Selection
No.
(Hex.)
Name Description
Default
(Range)
T3-00
(1198)
Control Loop Tuning
Selection
Sets the Control Loop Auto-Tuning method.
0
(0, 1)
0 : Inertia Tuning
1 : ASR (Speed Regulator)
■ T3-01: Test Signal Frequency
No.
(Hex.)
Name Description
Default
(Range)
T3-01
(0760)
Test Signal Frequency
Usually it is not necessary to change this setting. Sets the frequency of the test signal applied to
the motor during Inertia Tuning.
3.0 Hz
(0.1 - 20.0 Hz)
Lower the setting value if the load inertia is too significant and a fault is detected after the Inertia Tuning.
■ T3-02: Test Signal Amplitude
No.
(Hex.)
Name Description
Default
(Range)
T3-02
(0761)
Test Signal Amplitude
Sets the amplitude of the test signal applied to the motor during Inertia Tuning. Usually it is not
necessary to change this setting.
0.5 rad
(0.1 - 10.0 rad)
Lower the setting value if the load inertia is too significant and a fault is detected after the Inertia Tuning. Adjust
this parameter if a fault occurs when T3-01 [Test Signal Frequency] is set to a low value.
■ T3-03: Motor Inertia
No.
(Hex.)
Name Description
Default
(Range)
T3-03
(0762)
Motor Inertia
Sets the inertia of the motor. This value uses the test signal response to calculate the load inertia.
Determined by o2-04
(0.0001 - 6.0000 kgm
2
)
The default setting is for a Yaskawa standard motor as shown in the motor inertia table.
Note:
Capacities smaller than 37 kW are set in units of 0.0001 kgm
2
. Capacities 37 kW and larger are set in units of 0.001 kgm
