Auto-Tuning
The IMPULSE•VG+ Series 3 can adapt to all motors manufactured worldwide with its automatic
tuning function. The inverter asks the user for minimal motor information, then guides the user
through a quick simple tuning process. Ideally, perform a standard Auto-Tune with the motor
uncoupled from the load. When the motor cannot be disconnected from the load, perform a static or
non-rotating Auto-Tune.
NOTE: Contact Electromotive Systems service department if an auto-tune can not be performed.
After scrolling through the tuning parameters using the Up Arrow key, depress the RUN key to begin
auto-tuning. During tuning, “Tuning Proceeding” flashes on the digital operator display. When
complete, “Tune Successful”, is displayed. Depress the Menu key to exit auto-tuning mode. Please
refer to the “Fault Display and Corrective Actions at Auto-Tuning” section on page 6-19 if “Tune
Successful” is not displayed.
NOTE: If the STOP key is depressed during tuning, auto-tuning is interrupted and the motor
coasts to a stop. The data changed during tuning returns to its original values.
C A U T I O N
The brake output is not energized during auto-tune. The brake must be manually released and
unreleased when Auto-Tuning is complete.
