Function
The high-speed CNC inputs/outputs function supports the input or output of signals in the position-control/interpolation cycle. The high-speed CNC inputs/outputs can be used for machines, such as those used for grinding and laser machining, as well as in SINUMERIK Safety Integrated.
Input signals are possible for the following:
- Multiple feedrate values per block (calipers function)
The function allows modification of the feedrate through external signals. 6 digital inputs can be combined with 6 different feedrate values in a CNC block. There is no feed interruption in this case. An additional input can be used to terminate the infeed (starting a dwell time), and another input can be used to start immediate retraction. Depending on the input, the retraction of the infeed axis (or axes) is initiated by a previously specified absolute value in the IPO cycle. The remaining distance-to-go is deleted.
- Multiple auxiliary functions in the block
Several auxiliary functions can be programmed in one CNC block. These functions are transferred to the PLC depending on a comparison operation or an external signal.
- Axis-specific deletion of the distance-to-go
The high-speed inputs affect a conditional stop and deletion of the distance-to-go for the path or positioning axes.
- Program branches
The high-speed inputs make program branches within a user program possible.
- Fast CNC start
Machining can be enabled conditionally in the part program depending on an external input.
- Analog calipers
Various feedrates, a dwell time and a retraction path can be activated depending on an external analog input (threshold values are specified via machine data).
- Safety-related signals such as EMERGENCY STOP
Output signals are possible for the following:
- Position switching signals
The position switching signals can be output with the function Position switching signals/cam sequencer.
- Programmable outputs
- Analog value output
- Safety-related signals such as safety door interlock
