T3-00 Control Loop Tuning
Selection
(1198)
0 : Inertia Tuning
1 : ASR (Speed Regulator)
2 : Deceleration Rate Tuning
3 : KEB Tuning
Note:
Settings 0 and 1 are available only when A1-02 = 3, 7 [Control Method Selection = CLV, CLV/PM].

T3-01 Test Signal Frequency
(0760)
If the load inertia is too large and the drive detects a fault after Inertia Tuning, decrease the setting.
■
T3-02: Test Signal Amplitude
No.
Name
(Hex.)
T3-02 Test Signal Amplitude
(0761)
If the load inertia is too large and the drive detects a fault after Inertia Tuning, decrease the setting. If the drive
detects a fault when T3-01 [Test Signal Frequency] is set to a low value, adjust this parameter.

T3-03 Motor Inertia
(0762)
The default setting is for a Yaskawa standard motor as shown in the motor inertia table. Actual values will be
different when you use induction motors or PM motors.
Note:
The display units for the default setting and setting range are different for different models:
• 0.0001 kgm 2 units (setting range: 0.0001 kgm
• 0.001 kgm 2 units (setting range: 0.001 kgm
• 0.01 kgm 2 units (setting range: 0.01 kgm

V/f CL-V/f OLV CLV AOLV
Sets the type of Control Auto-Tuning.
V/f CL-V/f OLV CLV AOLV
Sets the frequency of the test signal applied to the motor during Inertia Tuning. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the amplitude of the test signal applied to the motor during Inertia Tuning. Usually it is not
necessary to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the inertia of the motor. This value uses the test signal response to calculate the load inertia.
2 to 6.0000 kgm 2 ): 2004 to 2021, 4002 to 4012
2 to 60.000 kgm 2 ): 2030 to 2211, 4018 to 4103
2 to 600.00 kgm 2 ): 2257 to 2415, 4140 to 4675
V/f CL-V/f OLV CLV AOLV
This parameter uses the load inertia value from the Inertia Tuning process to automatically
calculate and set C5-01 [ASR Proportional Gain 1].
