Non-Rotational Auto-Tune (T01-01 = 1) Instructions
A non-rotational Auto-Tuning method has been implemented into the IMPULSE
®
•VG+ Series 4 drive
which allows for Auto-Tuning without decoupling the motor.
This method will require a short movement of the crane subsequent to the non-rotational Auto-Tune
process which allows the drive to calibrate the Motor Rated Slip and No-Load Current.
The instructions below will provide a step-by-step procedure to complete the non-rotational segment
of this Auto-Tune function:
1. In preparation for the Auto-Tune, the crane should be unloaded with minimal hook attachments.
For Traverse motion, ensure freedom of travel for Step #6.
2. Using the keypad, browse to the “Auto-Tuning” menu.
3. Choose “Tune-No Rotate1” (T01-01 = 1) for the Tuning Mode.
4. Enter the nameplate motor characteristics (T01-02 ~ T01-09) until the “Tuning Ready?” screen is
reached.
5. Press the green “RUN” key to start the Auto-Tune. It will take up to a few minutes to complete.
During this time, the current will ramp up and down and a high pitched frequency may be audible
coming from the motor; this is normal. When the Auto-Tune has completed, the keypad display
will display an “End Tune Successful” message. Press the “ESC” key twice to exit.
6. Run the motor to at least 30% of the Rated Frequency (T01-05). For example, if the Rated
Frequency is 60 Hz, the motor must run to at least 18 Hz. In a hoisting motion, the motor must
be run in the Up/Raising direction.
NOTE: In hoisting motions, remove any loads or spreader bars.
7. When the short run and adjustments have been completed, the motor will stop, and the keypad
will display “TMDN Tune Complete”. The Auto-Tune is now complete and the drive is ready for
normal operation.
