10.2.4 Axis start after punching
Input signal "Stroke ON"
The start of an axis motion after stroke initiation is controlled via input signal "Stroke ON".
Figure 10-3 Signal chart: Axis start after punching
In this case, the time interval between t
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' - t
4
PONS/SONS
If the punch is controlled by PONS/SONS, the delay time is determined by:
|t' - t

Prerequisites: Stroke time (t
