1) Press start signal (output) PF <Y1004#2>
2) Press stop signal (input) *PE <X1004#7>
3) Punch finish signal for 1–cycle press (input) *PFIN <X1004#5>
In the punching block, the PF signal goes to 1 after positioning if tape or
memory command input is already selected. In the machine tool, this
signal makes the press start for punch operation. When the time set in
parameter 16030 elapses after the *PE signal goes to 0, the PF signal goes
to 0. Use the *PE signal to stop the press.
When the time set in parameter 16040 elapses after the *PFIN signal goes
to 0, processing goes to the next block.
The press starts stopping.

Fig. 3.5.1 (a) 1–cycle press process
Several parameters for the PF signal can be used to adjust the timing of
1–cycle press.
The PF signal can be set to 1 before the end of positioning depending on
setting in parameter 16012. If the set time is longer than the time required
for deceleration during axial movement, the PF signal goes to 1 at the
same time deceleration starts. If the condition for setting the PF signal
to 1 is satisfied in all X–, Y–, and C–axes, the PF signal goes to 1 during
simultaneous positioning for each axis. (See Fig. 3.5.1 (b).)
