RCK_CutOffsetAdjust (FB)

FUNCTION_BLOCK RCK_CutOffsetAdjust

This function block is implemented to adjust the offset between the acutal cutting position and the theoretical cutting position coresponding to the cutting parameters. By default, the offset is zero, that means the actual cutting position should be at the place where the registration is if registration detection is enabled.

With the rising edge of CoarseAdjustPositive/PreciseAdjustPositive, the actual cutting position will move toward positive direction which the material is coming by the distance CoarseAdjustment/PreciseAdjustment. With the rising edge of CoarseAdjustNegative/PreciseAdjustNegative, the actual cutting position will move toward negative direction which the material is going by the distance CoarseAdjustment/PreciseAdjustment.

This function block can only be activated when cutter state is in “Automatic”, “Paused” or “Resuming”.

Note

The units of CoarseAdjustment and PreciseAdjustment are the same as the unit of circumference of cutter set in RCK_Parameter.
