Precautions for Correct Use
• When you use the Pulse Output Unit with the MC Function Module, input signals from a Dig-
ital Input Unit are used for the positive limit input, negative limit input, immediate stop input,
and home proximity input. Always make sure that the signal widths for all of these input sig-
nals are longer than the task period where the MC Function Module is executed. If the input
signal widths are shorter than the task period, the MC Function Module may not be able to
detect the input signals, resulting in incorrect operation.
• To assign a Position Interface Unit to an axis in the MC Function Module, you must assign
NX Unit I/O Data Active Status

in the EtherCAT Coupler Unit. Replace “

” with 15,
31, 63, or 125 according to the highest NX Unit number of the EtherCAT Coupler Units. Refer
to the N
X-series EtherCAT Coupler Unit User’s Manual (Cat. No. W519) for details.
