1004 YASKAWA SIEPC71061737B GA800 Drive Technical Reference
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
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, C6-
01, and E5-01
(0.0001 - 600.00 kgm
2
)
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 2 to 6.0000 kgm 2 ): 2004 to 2021, 4002 to 4012
•
0.001 kgm 2 units (setting range: 0.001 kgm 2 to 60.000 kgm 2 ): 2030 to 2211, 4018 to 4103
• 0.01 kgm 2 units (setting range: 0.01 kgm 2 to 600.00 kgm 2 ): 2257 to 2415, 4140 to 4720

T3-04: System Response Frequency
No.
(Hex.)
Name Description
Default
(Range)
T3-04
(0763)
System Response Frequency
This parameter uses the load inertia value from the Inertia Tuning process to automatically calculate
and set
C5-01 [ASR Proportional Gain 1] .
10.0 Hz
(0.1 - 50.0 Hz)
If this input value is too high, it can cause oscillation.

T4: EZ Tuning
Use T4 parameters to input the data necessary for motor parameter Auto-Tuning when A1-02 = 8 [Control Method
Selection = EZ Vector Control] . These two modes are available:

*1 When you use a PM motor or a synchronous reluctance motor, it is not necessary to enter the rated frequency. The drive will use the rated
rotation speed and number of motor poles to automatically calculate the rated frequency.
