4.4.1 Standard Auto-Tune (T01-01 = 0)
This is a rotational Auto-Tuning method for Open Loop Vector and Flux Vector only, which allows for Auto-Tuning a
motor that is unloaded and ideally decoupled from the gearbox. The brake must also be disengaged.
The instructions below will provide a step-by-step procedure to complete this Auto-Tune function:
1. In preparation for the Auto-Tune, the crane should be with minimal attachments. This Auto-Tuning method
requires free rotation of the motor, so decoupling the motor from the load or gearbox is ideal.
2. Ensure the brake is disengaged.
3. Using the keypad, browse to the “Auto-Tuning” menu.
4. Choose “Standard Tuning” (T01-01 = 0) for the Tuning Mode.
5. Enter the nameplate motor characteristics (T01-02 – T01-08) until the “Tuning Ready?” screen is reached.
6. 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. The motor will then begin a rotational cycle, which will complete in one minute or less.
7. When the Auto-Tune has completed, the keypad display will display an “End Tune Successful” message.
Press the “ESC” key twice to exit.
NOTE:
If the STOP key is depressed during tuning, auto-tuning is interrupted and the motor coasts to a stop. The
data changed during tuning returns to its original values.
4.4.2 Non-Rotational 1 Auto-Tune (T01-01 = 1)
This is a non-rotational Auto-Tuning method for Open Loop Vector and Flux Vector only, 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 VFD to calibrate the Motor Rated Slip and No-Load Current.
The instructions below will provide a step-by-step procedure to complete 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.
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 VFD is ready for normal operation.
