Fully-closed Loop Control
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 is set to n.1, the encoder output phase-C pulse output width
may be narrower than the width of the phase-A pulse.
• As shown in the following diagram, there is a 1/8th scale pitch difference in the
encoder dividing phase-C pulse output position, the zero point return command,
and the phase-C detection position with the phase-C latch when Pn081 is set to
n.0 and when Pn081 is set to n.1.
Pn081 = n.0
Pn081 = n.1
