Depending on velocity and machine dynamics, approximately 3 - 5 interpolation cycles are
processed at the end of interpolation before the axes reach zero speed.
● MD26018 NIBBLE_PRE_START_TIME
● SD42402 NIBPUNCH_PRE_START_TIME
The following applies for the delay time:
MD26018 = 0 → SD42402 is effective
MD26018 ≠ 0 → MD26018 is effective
If the "Punching with dwell time,
connection with this function is active. Neither MD26018 nor SD42402 is operative in this
case.

In connection with MD26018, it is possible to delay, and therefore optimize, the instant
between reaching the end of interpolation and setting the high-speed output for "Stroke
ON".
SD42402 can be changed from the part program and therefore adapted to the punching
process depending on the progress of the part program run.
Description
The interpolation reaches the block end. In this case, the
axes continue to move until the overtravel has been
traversed, i.e. the signal is output at an appreciable
interval before the axes have reached zero speed (see
t" ).
1
The signal is output once the axes have reached the
coarse in-position window. If this criterion is selected for
stroke initiation output, then the instant of stroke initiation
can be varied through the size of interpolation window
(see t' ).

In this case, it can always be ensured that the machine
will have reached a standstill at the instant of punching
provided that the axis data is set appropriately. However,
this variant also results in a maximum dead time (see t
