Output Variable Update Timing
Name Timing for changing to TRUE Timing for changing to FALSE
InCombination When combining axes is started.
• When Error changes to TRUE.
• When CommandAborted changes to TRUE.
Busy When Execute changes to TRUE.
• When Error changes to TRUE.
• When CommandAborted changes to TRUE.
Active When the instruction is started.
• When Error
changes to TRUE.
• When CommandAborted changes to TRUE.
CommandAborted
• When this instruction is aborted because anoth-
er motion control instruction was executed with
the Buffer Mode set to Aborting.
• When this instruction is canceled due to an er-
ror.
• When this instruction is executed while there is
an error.
• When you start this instruction during MC_Stop
instruction execution.
• When Execute is TRUE and changes to
FALSE.
• After one period when Execute is FALSE.
Error When there is an error in the execution conditions
or input parameters for the instruction.
When the error is cleared.

Description
Master Master Axis _sAXIS_REF ---
Specify the master axis.
*1
Auxiliary Auxiliary Axis _sAXIS_REF ---
Specify the auxiliary axis.
*1
Slave Slave Axis _sAXIS_REF ---
Specify the slave 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.
Precautions for Correct Use
One of the following minor faults will occur if the different axes are not used for the master,
slave, and auxiliary axes.
•
Master and Slave Defined as Same Axis (error code 5436 hex)
• Master and Auxiliary Defined as Same Axis (error code 5437 hex)
• Auxiliary and Slave Defined as Same Axis (error code 548E hex)
Function
• The MC_CombineAxes instruction starts combining axes when Execute changes to TRUE.
