2-2-1 Procedures When Using the Motion Control Function Module
 Function Settings of MC Function Module
For details on the function settings of the MC Function Module, refer to the NJ/NX-series CPU Unit
Motion Control User's Manual (Cat. No. W507).
Also refer to 8-9-2 Precautions When Using the Pulse Output Unit on page 8-42.
Precautions for Correct Use
If you assign an NX Unit connected to an EtherCAT Coupler Unit as an I/O device for a MC
Function Module axis, the MC Function Module manages refreshing of the I/O data. In this
case, the MC Function Module manages refreshing of the I/O data for the entire Slave Termi-
nal, including the EtherCAT Coupler Unit.
If any of the operations or errors in the following table occur, the MC Function Module discards
the Slave Terminal I/O data at that time. Refreshing of I/O data resumes when valid data is
obtained again.
From several milliseconds to several tens of milliseconds is required to resume refreshing of
I/O data, depending on the system configuration and the process data communications cycle.
You can include an NX Unit that is not assigned to an axis in a Slave Terminal that is managed
by the MC Function Module, but keep in mind the above characteristics of the refreshing of I/O
data when you do so.
If you want to avoid the effects of the refreshing of I/O data that is managed by the MC Function
Module on NX Units that are not assigned to axes, place those NX Units on another Slave Ter-
minal. To use different Slave Terminals, use different EtherCAT Coupler Units and configure the
Slave Terminals so that one contains only NX Units that are assigned to axes and one contains
only NX Units that are not assigned to axes.
