A2.3 Autotune function of PI current regulator
The autotune procedure for the current regulator calculates the best gain values for the PI regulator. The procedure
can be used only when the drive is connected to a highly inductive load.
The autotune procedure can be launched from GF_eXpress (Parameter P915
Autotune
on the CURRENT
REGULATOR menu) or from the keypad via
Autotune
on the CURRENT REGULATOR menu. In order to run
autotune, the control method must be set to
Digital – Local
and the
Enable
and
Start
contacts must be closed.
When the procedure is launched from the keypad, the message "Start?" is displayed first. Press
Enter
to start
the procedure; press
CANC
to abort.
Whether the procedure is launched from the keypad or from GF_eXpress, when running its status is displayed
on the keypad and via the P1526
Autotune
Status
parameter
During normal running of autotuning, the keypad displays the message "Curr reg tuning" and the value of P1526
is set to 1 (In progress). If everything goes well, when the procedure ends the keypad displays the messages
"Ready" and "End curr tune" and parameter P1526 is set to 2 (Success).
The autotune procedure can be interrupted before it ends by pressing the
CANC
button on the keypad or from
GF_eXpress by clicking the
Disable
button on the Control Panel.
If the autotune procedure does not end correctly (due either to error events during the procedure or to interrup
-
tion commanded by the user) the PI parameters are reset to the values present before the procedure was started,
otherwise they are overwritten with the new values calculated.
In addition to the messages shown above regarding cases in which the procedure begins and ends correctly, the
keypad may also display the following messages:
"No current"
This message is displayed if, during the autotune procedure, the regulation cannot be
activated or if current is not calculated (not even with a proportional gain value of 100%).
