Single step mode on block numbers

Block number

When single-step mode is enabled, the CNC stops before each new motion block (see P-CHAN-00015) and waits for an acknowledgement from the PLC.

If the NC program was automatically generated by a post-processor based on CAD/CAM data, the original geometry information may result in several NC motion blocks. In this case a single step should correlate with the original granularity of CAD/CAM data and only stop at the original geometric resolution.

Another possible application case may be to explicitly disable single-step mode for individual blocks.

Block number related single-step resolution

Use the RESOLUTION option to define a block number-related single-step resolution:

0:     Off, no single step related to block numbers,

       Stop before each NC line

1:    Single step stops before each new programmed NC block number

> 1: A stop is executed before each block which can be divided into an integer

       with no remainder.

        <Ganzzahliges Ergebnis> = <Satznummer> / <Auflösung>

< 0: Impermissible value for single-step resolution, an error message

       is output.

Programming Example

Single-step resolution RESOLUTION to block numbers was set to 10.

In this case a stop is executed before each block can be divided by 10 into an integer with no remainder.

No stop is executed in the area displayed in italics in single-step mode. The black lines show the single-step stop.

To ensure effective diagnosis, all NC lines should always be provided with a unique block number.

Programming Example

Block numbering with user resolution (steps of ten) and internal numbering (single-step width).
