Auto-Tune Procedure
Auto-tuning is required only for Sensorless Vector Control Modes
(P2.10 = 02, 03, 05).
The DURA
PULSE AC drive is capable of performing an auto-tune procedure when
a motor is connected to the AC drive. It is also very important for safety and
functional reasons that no load be physically connected to the motor output shaft
during auto-tuning. The auto-tune will begin when the RUN key is pressed on the
AC drive keypad. To enable the Auto-Tune procedure, do the following:
Press the PROGRAM key repeatedly until the MOTOR GROUP, P0.00-P0-07, is
displayed on the keypad LCD display.
Press the ENTER key to display the various parameters for this group.
Use the UP/DOWN keys to display parameter P0.05, MOTOR AUTO-TUNE.
Press the ENTER key to display the current value for this parameter.

The "MOTOR AUTO-TUNE" display
text flashes during this step.
Use the UP/DOWN keys to change
the value in this parameter to either a
“1” to have the drive determine only
the motor line to line resistance R1
(P0.06) or “2” to determine R1 (P0.06)
and motor no-load current (P0.07).
Press the ENTER key to accept this
value and enable the AUTO-TUNE
function. The LCD display will indicate
with “MOTOR AUTO-TUNE, <STOP>
TO CANCEL” message for 3 seconds.
Proceed to the next page for steps to
initiate the auto-tune procedure.
WARNING: The motor will rotate when executing the auto-tuning procedure. It is also
very important that no load be connected to the motor output shaft at the time the
auto-tune procedure is performed.
