0 Hz is displayed as the initial value. Leave the setting at 0 Hz if the Motor Rated Slip Frequency is not known.
*3
If
T1-12 = 1 [Test Mode Selection = Yes]
, the drive will automatically set
E2-02 [Motor Rated Slip]
and
E2-03 [Motor No-Load
Current]
when first running the motor in the Drive Mode after the Auto-Tuning.
*4
Select this when
T1-10 [Motor Rated Slip Frequency]
= 0 Hz.
*5
Set the same value to No-Load Voltage as
T1-03 [Motor Rated Voltage]
to get the same characteristics using Yaskawa 1000-Series
drives or earlier models.

ASR and Inertia Tuning
To enhance the drive responsiveness and prevent hunting, use Auto-Tuning, which automatically adjusts the
control-related parameters.
The following types of Auto-Tuning are available for the control system:
•
Inertia Tuning
•
ASR Tuning
•
Deceleration Rate Tuning
Note:
When performing ASR and Inertia Tuning for the control system,
H1-xx = 16 [Motor 2 Selection]
cannot be used. Do not perform ASR
and Inertia Tuning for applications that switch between motor 1 and motor 3.

Inertia Tuning
Inertia Tuning estimates the system inertia based on the motor speed and torque reference and automatically sets
the drive parameters related to the inertia ratio of the machinery and motor. Use Inertia Tuning when using Feed
Forward Control.
Through identification of load inertia and optimization of speed loop gain and feed-forward gain, even higher
level control capabilities can be achieved. Moreover, speed response can be set without regard to the load, so
accuracy when synchronizing multiple drives is enhanced. Motors can continue to run during a power failure.
