15.4 Multi-step Skip Function 2; G31
Function and purpose
During linear interpolation followed by the skip command (G31), operation can be skipped
according to the conditions of the skip signal parameter Pp. Skip signal command P is specified
with the external skip signal 1 to 8.
If multi-step skip commands are issued simultaneously in different part systems, both part systems
perform skip operation simultaneously if the input skip signals are the same, or they perform skip
operation separately if the input skip signals are different. The skip operation is the same as with a
normal skip command (G31 without P parameter).

If the skip condition specified by the parameter "#1173 dwlskp" (external skip signals 1 to 8 are
used for the specification) is met during execution of a dwell command (G04), the remaining dwell
time is canceled and the following block is executed. Similarly, if the skip condition is met during
revolution dwelling, the remaining revolution is canceled and the following block is executed.
