In this case, the time interval between t
4
and t'
4
acts as a switching-time-dependent reaction
time. It is determined by the interpolation sampling time and the programmed
punching/nibbling mode.
PON/SON
When the punching unit is controlled via PON/SON, the maximum delay time is calculated to be:
|t'
4
- t
4
| = 3 x interpolation cycles
PONS/SONS
If the punch is controlled by PONS/SONS, the delay time is determined by:
|t'
4
- t
4
| ≤ 3 x position controller cycles
Prerequisites: Stroke time (t
4
- t
2
) > 4 interpolation cycles
