5-2-2 Axis Basic Settings
*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 1.04 or later and Sysmac Studio version 1.05 or higher are required for temporary
changes.
*6 Set this parameter when using the NX102 CPU Unit and NX1P2 CPU Unit.
*7 A CPU Unit with unit version 1.08 or later and Sysmac Studio version 1.09 or higher are required for temporary
changes.
*8 A CPU Unit with unit version 1.08 or later and Sysmac Studio version 1.09 or higher are required to use the
MC_WriteAxisParameter instruction.
The parameters that can be temporarily changed with the MC_WriteAxisParameter instruction can be read
with the MC_ReadAxisParameter instruction.
*9 A CPU Unit with unit version 1.11 or later and Sysmac Studio version 1.15 or higher are required to use this
parameter.
*10 A CPU Unit with unit version 1.05 or later and Sysmac Studio version 1.06 or higher are required to use this
parameter.
*11 This parameter is enabled only for torque control.
*12 A CPU Unit with unit version 1.01 or later and Sysmac Studio version 1.02 or higher are required for temporary
changes using the MC_Write instruction.
A CPU Unit with unit version 1.08 or later and Sysmac Studio version 1.09 or higher are required for temporary
changes using the MC_WriteAxisParameter instruction.
Refer to 3-2 Axis Setting Procedure for details on how to set axis parameters.
For details on instructions including the MC_Write (Write MC Setting) instruction, refer to the NJ/NX-
series Motion Control 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.
The Axis Basic Settings are used to set whether to use the axis. If you use the axis, set the axis type
and the node address of the EtherCAT slave device.

Parameter name Function Setting range Default
Axis Number Set the logical number of the axis. This number spec-
ifies which of the following system-defined variables
to use:_MC_AX[0] to _MC_AX[63].
