Program code Comment...N50 G331 S800 ; Master spindle with 2nd gear-stage data block: Gear stage 2is selected.N55 SPOS=0 ; Align spindle.N60 G331 Z-10 K5 ; Tapping, spindle acceleration from second gear-stage datablock.Example 4: No speed programming → monitoring of the gear stageIf no speed is programmed when using the second gear-stage data block with G331, then thelast speed programmed will be used to produce the thread. The gear stage does not change.However, monitoring is performed in this case to check that the last speed programmed iswithin the preset speed range (defined by the maximum and minimum speed thresholds) forthe active gear stage. If it is not, alarm 16748 is signaled.Program code CommentN05 M40 S800 ; Gear stage 1 is selected, the first gear-stage data blockis active....N55 SPOS=0N60 G331 Z-10 K5 ; Monitoring of spindle speed 800 rpm with gear-stage datablock 2: Gear stage 2 should be active, alarm 16748 is sig-naled.Example 5: Gear stage cannot be changed → monitoring of gear stageIf the spindle speed is programmed in addition to the geometry in the G331 block when usingthe second gear-stage data block, if the speed is not within the preset speed range (definedby the maximum and minimum speed thresholds) of the active gear stage, it will not be possibleto change gear stages, because the path motion of the spindle and the infeed axis (axes) wouldnot be retained.As in the example above, the speed and gear stage are monitored in the G331 block and alarm16748 is signaled if necessary.Program code CommentN05 M40 S500 ; Gear stage 1 is selected....N55 SPOS=0N60 G331 Z-10 K5 S800 ; Gear stage cannot be changed, monitoring of spindlespeed 800 rpm with gear-stage data block 2: Gear stage2 should be active, alarm 16748 is signaled.Example 6: Programming without SPOSProgram code CommentN05 M40 S500 ; Gear stage 1 is selected.Motion commands10.11 TappingFundamentalsProgramming Manual, 01/2015, 6FC5398-1BP40-5BA2 237 |
