Balance Adjust Flowchart 2
When Executing Tracking Balance Adjust
The Balance adjust is from $8000 to $81FF, and the Switch Mode is changed one STEP at a time by 16-bit
Data transmission. After Adjust is completed, a separate Latch Pulse is not necessary.
If the Trcnt Freq. is not high enough, the Balance can be adjusted at $F3 applied 2x Mode.
Here, we have suggested Tracking Off status for the Balance Adjust, but the same amount of Flow can be
Balance adjusted while in Track Move.
The Tracking Balance window Select level can be selected by D2 bit out of 12-bit Data. 0: -10 mv ~ +15 mv, 1:
-20 mv ~ +20 mv.
When the Tracking Balance Adjust is complete, start the Tracking Gain Adjust.
Start :$800
