Punching and Nibbling (N4)
15.3 Activation and deactivation
Turning, Milling, Nibbling
278 Function Manual, 11/2012, 6FC5397-1CP10-5BA0
If a punching dwell time (PDELAYON) is also programmed, then the two times are applied
additively.
If a pre-initiation time at
G603 is programmed, it will be effective only if the end of interpolation
is reached before the time set in SD 42404:
The programmed time becomes operative immediately. Depending on the size of the block
buffer, strokes that have already been programmed can be executed with this minimum
interval. The following programming measures (example) can be taken to prevent this:
N...
N100 STOPRE
N110 $SC_MINTIME_BETWEEN_STROKES = 1.3
The function is not active when SD42404 = 0.
Travel-dependent acceleration
An acceleration characteristic can be defined with PUNCHACC (Smin, Amin, Smax, Amax). This
command can be used to define different acceleration rates depending on the distance
between holes.
Example 1
$>@
381&+$&&
6>PP@
The characteristic defines the following acceleration rates:
Distance
between holes
Acceleration
< 2 mm The axis accelerates at a rate corresponding to 50% of maximum acceleration.
2 - 10 mm Acceleration is increased to 100%, proportional to the spacing.
> 10 mm The axis accelerates at the maximum rate (100%).
