Pressing a button on the press machine can output a press-in-progress
signal. It is possible to specify whether punching is to be performed on
one cycle only or to be continued while the button is pressed.
G70 specifies rapid traverse for positioning. A press start signal is not
output after positioning is completed.

The following parameters can be used to adjust the press start signal
output timing so that punching is smooth.
(1)Punching specification for forming mode
(2)Setting up an upper limit to the positioning offset for press start signal
output
(3)Timer setting (early PF) for outputting a press start signal before
positioning is completed
(4)Timer setting for executing the next block before press is completed
It is possible to inhibit the press start signal from being output.
It is possible to defer the output of the press start signal until the press is
ready to respond.
Up to two nibbling pitches can be specified according to an external signal
or an M-code in a parameter. This function can be used to select a
maximum traveling pitch for a machine in which the speeds of a flywheel
can be switched or according to the thickness of raw material.
In a block in which press start signal output is specified (except for
nibbling), an external operation signal, rather than the press start signal,
can be output as required by an external signal. This function can be used
for tapping.
