Note: A SERVOPACK with software version 0023 or later supports this parameter.
Parameter Meaning When Enabled Classification
Pn081
n.†††0
[Factory Setting]
Outputs phase-C pulse only in forward direction.
After restart Setup
n.†††1
Outputs phase-C pulse in forward and reverse
direction.
• 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.
