Terminal Resistance Auto-Tune (T01-01 = 2) Instructions

This is a non-rotational Auto-Tuning method for the IMPULSE®•G+ Series 4 drive which allows for
Auto-Tuning without decoupling the motor.
This method is recommended for motors configured with the V/f control method when the motor
horsepower and motor rated current are known.
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.
2. Using the keypad, browse to the "Auto-Tuning" menu.
3. Choose "Term Resistance" (T01-01 = 2) for the Tuning Mode.
4. Enter the nameplate motor characteristics for Motor Horsepower and Motor Rated Current (T01-
02 and T01-04) 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.
