System for System-defined Variables for Motion Control
System-defined variables for motion control consist of information representing the status of the MC
Function Module, status information for slave devices connected via EtherCAT communications and
NX Units mounted on the CPU Unit, and the portion of the MC parameter settings used to perform
motion control.
You can access system-defined variables for motion control as variables in the user program and
monitor them from the Sysmac Studio.
