Understanding the Auto-tuning
Procedure
Chapter Objectives The 1336 IMPACT drive runs the auto-tune routines as part of the
Quick Motor Tune routine.
Important: You can skip this chapter if your drive passed the auto-
tune tests performed during the Quick Motor Tune routine. You
should only need to read this chapter if your drive faulted during any
of the auto-tune tests.
What Is Auto-tuning? Auto-tuning is a procedure that involves running a group of tests on
the motor/drive combination. Some tests check the drive hardware
and other tests configure drive parameters to maximize the
performance of the attached motor.
Important: If you stop the drive once the resistance, inductance,
flux, and inertia tests begin, the drive will fault.

ATTENTION: You must apply power to the drive and
connect the motor for the auto-tune tests. Some of the
voltages present are at incoming line potential. To avoid
electrical shock hazard or damage to equipment, only
qualified service personnel should perform the
