• When LPG signal is turned on, position feedback signal is switched from motor PG to
line PG and position fully closed loop by line PG is formed.
• Line PG output pulse corresponds to reference data one-by-one. That is, one pulse
from line PG is read-in as one reference unit move.
• When line PG is used, zero-point return (homing) cannot be performed. Entering
zero-point return mode causes an error.
