T4: Ez Tuning - YASKAWA GA800 Series Technical Reference

12.12 T: Auto-Tuning
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.

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

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:
T4-01 Setting
0 Follow the instructions in the setup wizard on the keypad to
manually enter the necessary motor parameters.
1 Do only line-to-line resistance tuning.
*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.
