3. PRESSING FUNCTION
49
1) Manual press start signal (input) MPS <G230#3>
2) Continuous manual press signal (input) MNS <G230#4>
Setting the MPS signal to 1 can set the press start (PF) signal to 1. The
signal is used when a 1–cycle press operation is performed with the push
button on the machine operator’s panel.
During manual press operation, the control of the PF signal depends on
the status of the MNS signal. When the MPS signal changes from 0 to
1 in the state that the MNS signal is 0, the PF signal goes to 1. When the
time set in parameter 16030 elapses after the *PE signal goes to 0, the PF
signal goes to 0. (See Fig. 3.5.3 (a).)
When the MPS signal changes from 0 to 1 in the state that the MNS signal
is 1, the PF signal goes to 1. The state of the PF signal is held until the
MPS signal goes to 0. When the MPS signal changes from 1 to 0, the PF
signal goes to 0. (See Fig. 3.5.3 (b).)

When the PFL signal is 1, the PF signal does not go to 1, but can be locked
in the block for 1–cycle press. The tool completes positioning in the state
that the PFL signal is 1 and the time set in parameter 16031 elapses, then
the next block is executed. (See Fig. 3.5.4 (a).)

In the same way, the PF signal and the nibbling (NBL) signal do not go
to 1 in the block for nibbling when the PFL signal is 1. When the tool
completes positioning to the first punch point, the timer set in parameter
16034 starts. If the PFL signal is 1 in this case, the time set in parameter
16031 elapses, then the tool starts positioning to the next punch point.
If the PFL signal remains 1, the tool completes positioning for each pitch,
then the previously described processing is repeated. (See Fig. 3.5.4 (b).)
