Standard Auto-Tune (T01-01 = 0) Instructions

This is a rotational Auto-Tuning method for the IMPULSE
Auto-Tuning on an unloaded or decoupled motor.
This method requires that the motor be unloaded or decoupled from the load with the brake
disengaged.
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 attachments. This
Auto-Tuning method requires free rotation of the unloaded motor, so decoupling the motor from
the load may be necessary.
2. Ensure the break is not set during the Auto-Tuning process.
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.
