High-speed signals

Functionality
High-speed signals are used to synchronize the NC and punching unit. On the one hand,
they are applied via a high-speed output to ensure that the punch stroke is not initiated until
the metal sheet is stationary. On the other, they are applied via a high-speed input to ensure
that the sheet remains stationary while the punch is active.
The high-speed digital inputs and outputs on the control are used to drive the punching unit.
The following signal chart illustrates the signal sequence.

Note
The "Stroke active" signal is high-active for reasons relating to open-circuit monitoring.
