[Classification] Input signal
[Function] These signals terminate skip cutting. That is, the position where a skip
signal turns to “1” in a command program block containing G31P1 (or
G31), G31P2, or G31P3, G31P4 is stored in a custom macro variable, and
the move command of the block is terminated at the same time.
Furthermore, in a block containing G04, G04Q1, G04Q2, G04Q3 or
G04Q4, the dwell command of the block is terminated.
In either case, until all other commands (such as miscellaneous functions)
of the block are completed, machining never proceeds to the next block.
Which of the eight skip signals is applicable to blocks containing the G
codes can be determined by parameter (no. 6202 to 6206). The eight skip
signals can correspond to the G codes on a one-to-one basis. One skip
signal can also be made applicable to multiple G codes. Conversely,
multiple skip signals can be made applicable to one G code.
[Operation] When a skip signal turns to “1”, the control unit functions as described
below.
· When a block contains a G code from (G31, G31P1 to P4) for skip
cutting, and the skip signal is made applicable by parameter setting to
the command, the control unit reads and stores the current position of
the specified axis at that time. The control unit stops the axis, then
cancels the remaining distance that the axis was supposed to be moved
in that block.
· When a block contains a G04, or G04Q1 to Q4 code for dwell, and the
skip signal is made applicable by parameter setting to the command, the
control unit stops dwell operation, and cancels any remaining dwell
time.
· The skip signal is not monitored for a rising edge, but for its state. So,
if a skip signal continues to be “1”, a skip condition is assumed to be
satisfied immediately when the next skip cutting or dwell operation is
specified.
