06 LD Unit Position Displays the current LD unit position (number of
pulses from home position). If this is different
from the value of SP2109-01 or SP2109-02, LD
unit positioning has failed.
07 Pitch Change Count Displays how many times the LD unit position
has been changed (how many times the
resolution has changed.)
When the laser beam pitch adjustment is done,
this counter is reset to zero.

enters the energy saver mode, the polygon
motor will ignore the zero setting and switch
itself off.
