Auto-Tune Instructions
If the drive is set to auto-tune with no motor connected, the drive will go into an
infinite auto-tune loop without access to the parameter groups. To correct this
situation, simply power down the unit, connect the motor, complete auto-tuning
(even if incorrect), reset factory default (9.08 = 99), and then start over.
1. Make sure all wiring is correctly connected to the AC drive and motor.
2. Make sure there is no load connected to the motor’s output shaft, including any
belts or gear boxes.
3. Program parameters P0.00, P0.01, P0.02, P0.03 and P0.04 with the correct
values for the motor being used.
4. After enabling the Auto-Tune parameter P0.05 as shown on the previous page
for either a “1” to have the AC drive determine only the motor line to line
resistance R1 (P0.06), or a “2” to determine R1 (P0.06) and the motor’s no-load
current (P0.07), the message MOTOR AUTO-TUNE (flashing), <STOP> TO
CANCEL will appear on the keypad LCD display for a 3 second period. If the
STOP key is pressed during this time, the Auto-Tune procedure will terminate,
the value in parameter P0.05 will reset to “0” and the LCD display will return
to the display mode.
5. After the confirmation message is shown, (the AC drive is ready to perform an
Auto-Tune), the keypad LCD will display the message PRESS <RUN>, TO
CONTINUE for 60 seconds. Once the RUN key is pressed, the display will
show DETECTING MOTOR (flashing), <STOP> TO CANCEL. If the STOP key is
pressed, the Auto-Tune procedure will terminate, the keypad LCD display will
show either a “R1 Detect Error” or “No Load Error” warning message, and the
value in parameter P0.05 will reset to “0”. Use the STOP/RESET key to clear
the warning message and return the drive to the display mode. Then repeat the
procedure.
6. The Auto-Tune procedure will take approximately 15 seconds to execute, plus
the acceleration and deceleration times in parameters P1.01 and P1.02. (The
greater the horsepower of the AC drive and motor, the more acceleration and
deceleration time will be required.)
7. Upon completion of the Auto-Tune procedure, the display will show the
message TUNING COMPLETE, PRESS <ENTER>. At this time, the determined
values for parameters P0.06 and P0.07 will be filled in automatically. Please
check these parameters to make sure a value was determined. If no value was
determined, then repeat the procedure.
8. If the STOP/RESET key on the keypad is pressed during auto-tuning, or if the
RUN key is not pressed within 60 seconds once the message PRESS <RUN>,
TO CONTINUE is displayed, the Auto-Tune procedure will terminate and the
value in parameter P0.05 will reset to “0”. The
DURA
PULSE
AC drive will
return to the normal display mode.
Do NOT set auto-tuning without a motor connected to the drive.
Do NOT set auto-tuning with any mechanical load connected to the motor output
shaft.
It is not necessary to set up the encoder and control mode before performing the auto-
tuning function. (Auto-tuning is required only for the sensorless vector control modes.)
