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.
