• Setting of Pn081.0

Do not change the factory setting if the zero point position of the existing equipment
must remain as is.

• When Pn081.0 = 1, the width of the phase-C pulse output is narrower than that of

the phase-A pulse in some cases.

• As shown in the following figure, there is a one-eighth scale pitch difference in posi-

tions between the two settings (Pn081.0 = 1 and Pn081.0 = 0) for the phase-C
pulse output, the zero point return command, and the phase-C detection by phase-
C latch function.
