The following shows the update timing of mark detection positioning data and mark detection edge data when
a mark detection signal is detected and both ON/OFF edges are enabled in the mark detection data settings.

When the mark detection signal turns ON/OFF
at an interval shorter than the 0.88ms control
cycle, the edge information that was first detected
applies.

Use a software version that supports mark detection for the servo amplifier. Mark detection is compatible with
SSCNET
/H communication method only. Servo amplifier software versions that support mark detection are
shown in the table below.
