3 Axis Command Instructions
LinkOption (Synchronization Start Condition)
Specify the condition for the slave axis to synchronize with the master axis.
• Start of Instruction
When this instruction is executed, the slave axis performs positioning in synchronization with the
master axis from the next period.
• When Trigger Is Detected
When the input signal specified as the input trigger occurs, the slave axis synchronizes with the
master axis and performs positioning from the next period.
• When the Master Axis Reaches the Master Following Distance
When the master axis reaches the master following distance during instruction execution, the
slave axis starts synchronization and performs positioning from the next period.
Even if the instruction is executed while the master axis is stopped at the master following dis-
tance, the slave axis starts synchronization and performs positioning from the next period.
Precautions for Correct Use Precautions for Correct Use
You must map object data when LinkOption (Synchronization Start Condition) is set to_mcTrigg-
erDetection and Mode is set to Drive Mode. Set the following objects.
• 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. For details on mapping object data, refer to the NJ/NX-series CPU Unit
Motion Control User's Manual (Cat. No. W507) or NY-series Industrial Panel PC / Industrial Box
PC Motion Control User's Manual (Cat. No. W559).
MasterStartDistance
MasterStartDistance specifies the absolute position where the slave axis starts synchronization with
the master axis.
CPU Units with Unit Version 1.10 or Later
When the Count Mode of the master axis is Rotary Mode, you can specify a MasterStartDistance
(Master Following Distance) outside the range specified by the modulo maximum position and mod-
ulo minimum position setting values. If you do, the relationship between the master axis current
position and the master axis following distance will be the same as when no direction is specified for
Direction in the MC_MoveAbsolute (Absolute Positioning) instruction. Refer to MC_MoveAbsolute
on page 3-49 for information on the MC_MoveAbsolute (Absolute Positioning) instruction.
CPU Units with Unit Version 1.09 or Earlier
If the Count Mode for the master axis is Rotary Mode, specify a value that is within the range speci-
fied by the modulo maximum position and modulo minimum position setting values for MasterStart-
Distance (Master Following Distance). If the value is not within the limits, an Cam Master Axis
Following First Position Setting Out of Range error (error code 547B hex) is output when the instruc-
tion is executed.
