• Touch probe function (60B8 hex)
• Touch probe status (60B9 hex)
• Touch probe pos1 pos value (60BA hex)
• Touch probe pos2 pos value (60BC hex)
If even one of the required objects is not set, a Process Data Object Setting Missing error (error
code 3461 hex) occurs.

Instruction Details
This section describes the instruction in detail.
Master (Master Axis)
Specify the master axis with Master.
Slave (Slave Axis)
Specify the slave axis with Slave.
TriggerInput (Trigger Input Condition) and TriggerVariable
These variables specify the input signal on which to start synchronization when the sync start condi-
tion is set to _mcTriggerDectection. For the input signal selection and information on the timing when
a trigger is generated, refer to MC_TouchProbe on page 3-336. If the Drive Mode is specified for
Mode in TriggerInput (Trigger Input Condition), a drive input from the slave axis is used. If the Con-
troller Mode is specified, TriggerVariable is used as the trigger signal.
ReferenceType (Position Type Selection)
You can select one of the following position types.
• _mcCommand: Command position (value calculated in the previous task period)
The master axis command position that was calculated in the previous task period is used for the
current period.
The command value that was calculated for the master axis in the last periodic task is used to cal-
culate the command position of the slave axis in the current period.
• _mcFeedback: Value obtained in the same task period
The actual position of the master axis that was obtained in the same task period is used.
• _mcLatestCommand: Command position (value calculated in the same task period)
The command position of the master axis that was calculated in the same task period is used.
This enables the use of information that is more recent than for _mcCommand. However, the axis
number of the master axis must be set lower than the axis number of the slave axis.
If the axis number of the slave axis is lower than the axis number of the master axis, Error will
change to TRUE. A Master/Slave Axis Numbers Not in Ascending Order error (error code: 5438
hex) will be output to ErrorID.
Precautions for Correct Use Precautions for Correct Use
Here, the task period is the primary period if the task is the primary periodic task and the task
period of the priority-5 periodic task if the task is the priority-5 periodic task. In the same way, the
periodic task is the primary periodic task or the priority-5 periodic task.
