Auto-Tuning
Auto-Tuning
uses
motor
characteristics
to
automatically
set
drive
parameters
for
vector
control.
Think
about
the
type
of
motor,
drive
control
method,
and
the
motor
installation
environment
and
select
the
best
Auto-Tuning
method.
The
keypad
will
show
the
messages
with
prompts
to
input
the
necessary
parameter
information.
These
prompts
are
specified
by
the
selected
Auto-Tuning
method
and
the
control
method
setting
in
A1-02

Auto-Tuning for Induction Motors
This section gives information about Auto-Tuning for induction motors. Auto-Tuning sets these parameters:
•
Motor parameters
E1-xx, E2-xx
(
E3-xx, E4-xx
for motor 2)
•
Speed feedback detection-use
F1-xx
(only with CLV)
Note:
Do Stationary Auto-Tuning if you cannot do Rotational Auto-Tuning. There can be large differences between the measured results and the
motor characteristics when Auto-Tuning is complete. Examine the parameters for the measured motor characteristics after you do Stationary
Auto-Tuning.

Rotational Auto-Tuning
T1-01 = 0
•
When you can decouple the motor and load the motor
can rotate freely while Auto-Tuning.
•
When operating motors that have fixed output
characteristics.
•
When it is necessary to use motors that have high-
precision control.
•
When you cannot decouple the motor and load, but
the motor load is less than 30%.

Stationary Auto-Tuning 1
T1-01 = 1
•
When you cannot decouple the motor and load, but
the motor load is more than 30%.
•
When the information from the motor test report or
motor nameplate is not available.
With Stationary Auto-Tuning, the energized drive
stays stopped for approximately 1 minute. During this
time, the drive automatically measures the necessary
motor parameters.
•
When operating the motor with a light load after
Auto-Tuning.
The drive can automatically calculate the motor
parameter settings necessary for torque control. Set
T1-12 = 1 [Test Mode Selection = Yes]
to do a test
run after Auto-Tuning.

Line-to-Line Resistance
T1-01 = 2
•
After Auto-Tuning, the wiring distance between the
drive and motor changed by 50 m or more.
•
When the wiring distance is 50 m or more in the V/f
Control mode.
•
When the motor output and drive capacity are
different.

Input Data for Induction Motor Auto-Tuning
To do Auto-Tuning, input data for the items in
that have an "x". Before starting Auto-Tuning, prepare the
motor test report or record the information on the motor nameplate as a reference.
