Compatibility With Earlier Systems - Siemens SINUMERIK 840D sl Function Manual

N4: Own channel - only 840D sl
10.3 Activation and deactivation
The characteristic defines the following acceleration rates:
Distance be‐
tween holes
< 3 mm
3 - 8 mm
> 10 mm
If a reduced acceleration rate has already been programmed via ACC, then the acceleration
limits defined with PUNCHACC refer to the reduced acceleration rate.
The function is deselected with:
S
min
The acceleration rate programmed beforehand with ACC remains operative.
Block search
In the case of a search for a block containing a nibbling function, it is possible to program
whether the punch stroke is executed at the block beginning or suppressed.
The setting is programmed in machine data:
MD11450 $MN_SEARCH_RUN_MODE
Bit
5

Compatibility with earlier systems

Use of M functions
As in earlier versions, macro technology allows special M functions to be used instead of
language commands (compatibility).
The M functions and equivalent language commands as used in earlier systems are as follows:
M20, M23
M22
626
Acceleration
The axis accelerates at a rate corresponding to 75 % of maximum acceleration.
Acceleration is reduced to 25 %, proportional to the spacing.
The axis accelerates at the maximum rate (25 %).
= S = 0

Value Meaning
0 Punch stroke at beginning of block is suppressed.
1 Punch stroke at beginning of block is executed.
