the Buf
fer Mode set to Aborting.
• When this instruction is canceled due to an er-
ror.
• When this instruction is executed while there is
an error.

Description
Axis Axis _sAXIS_REF ---
Specifies the axis.
*1
*1. Specify a user-defined Axis Variable that was created in the Axis Basic Settings of the Sysmac Studio (default: MC_Ax-
is*) or a system-defined axis variable name (_MC_AX[*]).
If you use Sysmac Studio version 1.29 or higher
, you can specify the system-defined axis variable name for AT specifi-
cation of a user-defined variable. This will allow you to specify the user-defined variable.
If you use Sysmac Studio version 1.28 or lower, do not specify any user-defined variable created in the variable table.
Function
• The MC_Stop instruction decelerates an axis from the current velocity to a velocity of 0.
