5-3 Axes Group Parameters
Use the axes group parameters to set axes group operations related to axes groups that the MC Func-
tion Module controls, such as the axis configuration, maximum interpolation velocity, and axes group
stopping method. The axes group parameters are provided for each axes group. The number of axes
groups depends on the model. Refer to 1-4-2 Performance Specifications on page 1-7 for details. The
same parameter settings are provided for each axes group. This section describes only the parameters
for axes group 1.
Use the Sysmac Studio to set the axes group parameters for each axes group.
*1 This column indicates if you can use instructions to temporarily change the settings.
*2 This column indicates whether you can access the parameter with a variable in the user program.
*3 Set this parameter when using the NX701 CPU Unit.
*4 A CPU Unit with unit version 1.10 or later and Sysmac Studio version 1.12 or higher are required to use this
parameter.
*5 A CPU Unit with unit version 1.01 or later and Sysmac Studio version 1.02 or higher are required to use this
instruction.
Refer to 3-4 Setting Procedures for Axes Groups for details on how to set axes group parameters.
For details on the MC_Write (Write MC Setting) and MC_ChangeAxesInGroup instructions, refer to the
NJ/NX-series Motion Instructions Reference Manual (Cat. No. W508).
Refer to 6-6 System-defined Variables for Motion Control for information on system-defined variables
for motion control.
