(1) If the skip signal is turned ON at the last of an operation, a deceleration stop
will occur and the operation will be terminated.
(2) When a control is skipped (when the skip signal is turned ON during a
control), the positioning complete signals will not turn ON.
(3) When the skip signal is turned ON during the dwell time, the remaining dwell
time will be ignored, and the next positioning data will be executed.
(4) When a control is skipped during interpolation control, the reference axis
skip signal is turned ON. When the reference axis skip signal is turned ON,
a deceleration stop will be carried out for every axis, and the next reference
axis positioning data will be executed.
(5) The M code ON signals will not turn ON when the M code output is set to
the AFTER mode (when "1: AFTER mode" is set in "[Pr.18] M code ON
signal output timing").
(In this case, the M code will not be stored in "[Md.25] Valid M code".)
(6) The skip cannot be carried out by the speed control and position-speed
switching control.
(7) If the skip signal is turned ON with the M code signal turned ON, the
transition to the next data is not carried out until the M code signal is turned
OFF.
