Linear interpolation can be commanded by specifying axial move
following the G31 command, like G01. If an external skip signal is input
during the execution of this command, execution of the command is
interrupted and the next block is executed.
The skip function is used when the end of moving is not programmed but
specified with a signal from the machine, for example. It is used also for
measuring the dimensions of a workpiece.

it is specified)

The coordinate values when the skip signal is turned on can be used in a
custom macro because they are stored in the custom macro system
variable #5061 to #5062, as follows:
#5061 X axis coordinate value
#5062 Z axis coordinate value
WARNING
Disable feedrate override, dry run, and automatic
acceleration/deceleration (with parameter No. 6200 and
subsequent parameters) when the feedrate per minute is
specified, allowing for an error in the position of the tool
when a skip signal is input. These functions are enabled
when the feedrate per rotation is specified.
