Step 7. After CURRENT LIMIT (P.005), what happens next depends on the

regulation type. If you selected:

V/Hz Regulation: Quick Start is complete and you are returned to the Main
Menu.

Vector Regulation: The self-tuning screen is displayed, as shown in figure
5.3. Go to step 8.

Step 8. If you want the drive to self-tune, select YES. See section 5.4 for information

about self-tuning. When self-tuning is complete, Quick Start is complete, and
you are returned to the Main Menu.

If you do not want the drive to self-tune, select NO. The parameter entry screen
for MAGNET CURRENT PRCNT (U.006) is displayed. After you have
programmed this parameter, Quick Start is complete, and you are returned to
the Main Menu.

Important: If you do not select SENSORLESS for the ENCODER PPR parameter

(U.001), and you select NO to self-tuning, you must ensure that the value
in ENCODER PPR (U.001) is accurate.

5.4

Self-Tuning Drives Programmed for Vector
Regulation

Self-tuning helps you set up the drive. It determines the proper no-load current value
for MAGNET CURRENT PRCNT (U.006) and, for flux vector control, the encoder PPR
value for ENCODER PPR (U.001). These values must be accurate to ensure that
rated motor torque, speed, and horsepower can be developed for drives programmed
for vector regulation (FVC or SVC).

Self-tuning can be performed as part of the Quick Start procedure, or as a separate
procedure.
