Auto tuning is recommended to achieve optimum performance. In addition, the iQpump drive requires Line-To-Line Resistance auto-
tuning before it can properly perform the Estimated Speed Search method. This method of speed search allows for bi-directional speed
search. The T1 parameters are found under the Auto-Tuning menu.
To perform auto-tuning follow these steps:
1. T1-02 should be left at the default value (the last 3 digits of the iQpump drive model number).
2. In T1-04, enter the Full Load Amps (FLA) as stamped on the motor's nameplate.
3. Press the INCREASE key once to display this:
4. If ready, press the HAND key once to start auto-tuning. This process will last for approximately 15 seconds. Once auto-tuning is
finished, the digital operator will display this:
5. To exit the Auto-Tuning menu, press the MENU key once.
Note: It is possible to a get a "Data Invalid" error if the either T1-02 or T1-04 fall outside the range of what the iQpump drive
will accept as reasonable levels for the programmed size of the iQpump drive (o2-04).
