Step 5. The message “Self Tuning is active” blinks on the screen during self-tuning.
The current minor loop takes a few seconds to self-tune. The speed loop
takes about two minutes. During self-tuning, you can go to monitor mode
without disrupting self-tuning.
Important: If you go into monitor mode during self-tuning, you must return to program
mode at completion of self-tuning to see the following screen. Self-tuning
is complete when the drive stops running.
When self-tuning is complete, the screen shown in figure 5.5 is displayed. If
you selected only one of the loops, only the information for that loop is
displayed.
The two parameters shown here (
NORMALIZED
INDUCTANCE
and
NORMALIZED
INERTIA
) are configured by self-tuning.
NORMALIZED
INDUCTANCE
is the
normalized armature inductance as measured by
CML
self-tuning.
NORMALIZED
INERTIA
(P.222) is the time required to accelerate the motor and
load inertia from zero to base speed (see the software manual for more
information on this parameter).
Step 6. Press to clear the message. The display returns to the menu you
started from.
Step 7. To save the changes through a power cycle, you must use Memory Save,
described in section 4.4.
See the hardware manual for final adjustments to the drive before beginning normal
operation.
