IMPULSE•G+ Mini Advanced Instruction Manual – March 2014
4-20
Auto-Tuning
The IMPULSE•G+ Mini can adapt to all motors manufactured world wide with its automatic tuning
function. The drive asks the user for minimal motor information, and then guides them through a
quick, simple tuning process. Ideally, perform a rotational Auto-Tune with the motor uncoupled
from the load. When the motor cannot be disconnected from the load, perform a stationary or non-
rotating Auto-Tune.
NOTE: Contact Magnetek Inc. Service Department if an Auto-Tune can not be performed.
The IMPULSE•G+ Mini can perform both a stationary and rotational Auto-Tune in the Advanced
Mode. For optimal performance, a rotational Auto-Tune should be performed.
CAUTION
The brake output is not energized during Auto-Tune. The brake must be manually released
before Auto-Tuning and unreleased when Auto-Tuning is complete.

NOTE: *Provides iron loss for determining Energy Saving coefficient. When power is cycled, the value set to E02.10 will appear
(the motor iron loss). If T01.02 is changed, an initial value for the motor capacity will appear that is close to the capacity
that was changed.
