Data type Description
BOOL Function block enable.
When EN = TRUE, execute current MC_TouchProbe computation.
When EN = FALSE, there is no computation.
Applies only to LD programs.
AXIS_REF See also AXIS_REF data type
FB_AXIS_REF See also FB_AXIS_REF data type
USINT Only embedded motion supported.
BOOL When TRUE, starts touch probe recording at the rising edge.
BOOL When TRUE, only use the window (defined here) to accept trigger events.
Motion resolution is limited to the Motion Engine interval configured by the user.
For WindowOnly TouchProbe functionality, there is a maximum response time delay that
is equal to the Motion Engine interval for both FirstPosition and LastPosition activation.
The maximum possible lag in the triggering position (both FirstPosition and LastPosition)
can be calculated by (Motion Engine interval * moving velocity).
REAL Start position of the window from where trigger events are accepted (in technical units
[u]). Value included in window.
REAL Stop position of the window from where trigger events are not accepted (in technical
units [u]). Value included in window.
BOOL Enable out.
Applies only to LD programs.
AXIS_REF Axis output is read-only in LD programs.
See also AXIS_REF data type
USINT Only embedded motion supported.
BOOL When TRUE, trigger event was recorded.
BOOL When TRUE, the function block is not finished.
BOOL When TRUE, the command was aborted by the MC_Power(OFF), or Error Stop function
block.
BOOL When TRUE, an error was detected.
UINT Error identification.
See also Motion control function block error IDs
REAL Position where trigger event occurred (in technical units [u])
Motion is an open-loop motion.
The axis position at the time the trigger event occurs. If the axis motion is an open-loop
motion, the commanded position (not an actual position) at the time the trigger event
occurs, assuming there is no motion delay between the drive and the motor.
