3 Axis Command Instructions
Refer to I/O Entry Mappings in the NX-series Position Interface Units User's Manual (Cat. No. W524)
for information on using the NX-series Position Interface Units.
Refer to Fixed PDO Mapping in the GX-series EtherCAT Slave Units User's Manual (Cat. No. W488)
for information on using encoder input slaves.
Instruction Details
This section describes the instruction in detail.
Specifying Axis
• Axis specifies the axis for which to latch the position.
• If the specified Axis is enabled by the MC_GroupEnable (Enable Axes Group) instruction, the
MC_TouchProbe (Enable External Latch) instruction causes an error and is not executed.
• For each axis, you can specify LatchID to execute up to two MC_TouchProbe (Enable External
Latch) instructions at the same time.
• LatchID is also used to specify the latch to abort for the MC_AbortTrigger (Disable External Latch)
instruction.
Additional Information
• Latching a position is also possible if an encoder axis that is connected to an OMRON GX-
series GX-EC02
• If you use an NX-series Pulse Output Unit, you can also perform latching with this instruction.
Refer to the NX-series Position Interface Units User's Manual (Cat. No. W524) for details.
Trigger Input Condition
Select the trigger conditions with Mode, LatchID, and InputDrive of the TriggerInput (Trigger Input
Conditions) variable.
Mode
• The mode can be set to Drive Mode to specify a signal from the Servo Drive or other device
as the trigger, or to Controller Mode to specify a trigger with TriggerVariable.
• The trigger occurs on the rising edge of the trigger signal. The axis position is latched on the
first trigger (FALSE to TRUE) after the MC_TouchProbe instruction is executed.
• While this instruction is Busy (Executing), a change in TriggerVariable is taken as a trigger
even if Execute is FALSE.
Additional Information
Set Mode to _mcDrive (Servo Drive Mode) if you use an OMRON GX-series GX-EC02
CAT Encoder Input Slave.
Drive Mode
For trigger detection and latching of the actual position, the latched actual position is more precise in
Drive Mode (which is a function of the Servo Drive or other device) than it is in Controller Mode.
3-340
EtherCAT Encoder Input Slave is used.
