Omron Sysmac NY-series User Manual

Function
• Latching is used to control positioning based on the point where a trigger signal occurs, such as a
signal from a sensor input. The position of the axis is recorded (i.e., latched) when the trigger signal
occurs.
•
The position of the axis that is specified with Axis is output to RecordedPosition (Latched Position)
according to the trigger settings.
As trigger settings, you can specify TriggerInput (Trigger Input Condition), WindowOnly,
FirstPosition, LastPosition, and StopMode.
• The output value of RecordedPosition (Latched Position) is held until the axis position is recorded
again by the same MC_TouchProbe (Enable External Latch) instance.

Mapping Data Objects
You must map the following object data when the MC_TouchProbe (Enable External Latch) instruction
is executed with Mode set to Drive Mode.
Mapping is performed in the Detailed Settings Area of the Axis Basic Settings Display of the Sysmac
Studio.
Axes Type Set to Servo Axis
• Touch probe function (60B8 hex)
• Touch probe status (60B9 hex)
• Touch probe pos1 pos value (60BA hex)
• Touch probe pos2 pos value (60BC hex)
Axes Type Set to Encoder Axis
• Touch probe function (4020 hex)
