Auto tuning is recommended to achieve optimum performance. In addition, the iQpump drive requires Line-To-Line Resistance auto-

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.

will accept as reasonable levels for the programmed size of iQpump drive (o2-04).
