32. AUTOTUNE
MENU
32.1.
Overview
NOTE
See the FIRST STARTUP section for tuning based on the control algorithm to be used.
NOTE
At the end of the Autotune procedure, the system automatically saves the whole
parameter set of the drive.
NOTE
Autotune must be performed only after entering the motor ratings or the ratings of the
encoder used as a speed feedback. Please refer to the MOTOR CONFIGURATION
MENU and the ENCODER/FREQUENCY INPUTS MENU.
The selected motor may be tuned in order to obtain the machine ratings or the parameterization required for the
correct functioning of the control algorithms. The user can also check the proper operation/wiring of the encoder
used as a speed feedback.
The Autotune menu includes two programming inputs,
I073
and
I074
. Input
I073
allows enabling and selecting the
type of autotune. Input
I074
—which can be programmed only if
I073
= Motor Tune— describes the type of
autotune which is performed. Because the values set in
I073
or
I074
cannot be changed once for all and are
automatically reset after autotune, the
ENABLE-A ENABLE-B
signals must be disabled and the
ESC
key must be
used to accept the new value.

Set
I073
as Motor Tune to enable autotune functions that can be selected with
I074
.
NOTE
For the correct operation of the tuning algorithms, enter the motor ratings and the ratings
of the encoder used as a speed feedback.
If the carrier frequency is changed via parameters
C001
or
C002
, the current control loop
and the flux control loop of the VTC or FOC regulator are to be adjusted again (see
“VTC” Control Algorithm and “FOC” Control).
The autotune procedure computes the motor parameters and the regulators parameters
regardless of the control algorithm selected via
C010
/
C053
/
C096
. Therefore, it is
possible to perform the autotune procedure before selecting the type of motor control to
be applied.
Please refer to the MOTOR CONFIGURATION MENU and the ENCODER/FREQUENCY
INPUTS MENU.
