Punching ON (in position control cycle)

PONS behaves in the same way as PON. For explanation, please refer to SONS.

Punching with delay ON

PDELAYON is a preparatory function. This means that PDELAYON is generally programmed

before PON. The punch stroke is output with a delay when the programmed end position is

The delay time in seconds is programmed in setting data:

SD42400 $SC_PUNCH_DWELLTIME

If the defined value cannot be divided as an integer into the interpolator clock cycle, then it is

rounded to the next divisible integer value.

The function has a modal action.

Punching with delay OFF

PDELAYOF deactivates punching with delay function, i.e. the punching process continues

normally. PDELAYON and PDELAYOF form a G code group.

Programming example:

SPIF2 activates the second punch interface, i.e. the stroke is controlled via the second pair

of high-speed I/Os (see Section "Channelspecific machine data (Page 650)", MD26004 and
