T3: Asr And Inertia Tuning; T4: Ez Tuning - YASKAWA GA700 Technical Manual

11.12 T: Auto-Tuning
If the amount of PG (pulse generator, encoder) Z-pulse offset is unknown, or the encoder has been replaced,
perform Z Pulse Offset Tuning and correct for the offset (Δθ) from the Z phase.

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.

The default setting is for a Yaskawa standard motor as listed in the motor inertia table. Actual values vary
depending on whether the motor used is an induction motor or a PM motor.
Note:
Capacities below 37 kW are set in units of 0.0001 kgm

T4: EZ Tuning

With the T4 parameters, the data required for motor parameter auto-tuning is input when setting A1-02 = 8
[Control Method Selection = EZ Open Loop Vector Control]. The following two modes are available.
922
V/f CL-V/f OLV CLV AOLV
Selects the Control Auto-Tuning method to be used.
V/f CL-V/f OLV CLV AOLV
Normally there is no need to change this setting. Sets the frequency of the
test signal applied to the motor during Inertia Tuning.
V/f CL-V/f OLV CLV AOLV
Sets the amplitude of the test signal applied to the motor during Inertia
Tuning. Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the inertia of the motor. This value is used to determine the load inertia
using the test signal response.
2 . Capacities 37 kW and above are set in units of 0.001 kgm
V/f CL-V/f OLV CLV AOLV
C5-01 [ASR Proportional Gain 1] is automatically calculated and set using
the load inertia value derived by the Inertia Tuning process.
