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 sav
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.
32.1.1. MOTOR AUTOTUNE AND ADJUSTING LOOPS
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.
