5 Motion Control Parameters
5-2
NJ-series CPU Unit Motion Control User’s Manual (W507)
5-1 Introduction
You can use motion control instructions to perform single-axis operations and multi-axis operations on
axes groups with the NJ-series CPU Unit’s MC Function Module. Axis and axes group parameters are
used to set these operations. Axis parameters must be set, but axes group parameters are not required
if you do not use multi-axis operations for axes groups.
These parameters are called motion control parameter settings (MC parameter settings).
*1 There are no MC Common Parameter Settings for the current version of the MC Function Module.
*2 Use the Synchronization menu command of the Sysmac Studio to upload and download the project.

Data Flow for Setting MC Parameters
• Download your MC Parameter Settings to the CPU Unit using the Sysmac Studio to save those
settings in the CPU Unit's non-volatile memory.
• Saved settings are applied to the main memory after you download them or when the power is
turned ON.
• If there are no problems with the saved settings, the MC Function Module executes control based
on the settings in the main memory.
• The settings of some of the parameters can be accessed as system-defined variables for motion
control.
• You can upload and download MC parameter settings regardless of the CPU Unit’s mode or the
status of the MC Function Module.
• When you start the download process, all axes in motion will stop immediately and the Servo will
turn OFF.

Overwriting Parameters with the MC_Write (Write MC Setting) Instruction
• You can use the MC_Write (Write MC Setting) motion control instruction to change the settings of
some parameters in the main memory while the user program is running.
• If the specified setting value is outside the allowed range, the output variable Error from the
instruction changes to TRUE and the parameter setting is not changed.
• Parameter settings become valid in either of the following two situations.
• The axis or axes group is stopped and you execute an instruction for an axis command or
axes group command.
• You set the Buffer Mode Selection for the instruction to Aborting and execute more than one
instruction.
