# Type 5: Block search at program end

## Block search type 5:

Continuation position at program end

This special block search type is used in particular in job planning on a simulation system for a rapid test of NC programs. The continuation position is placed implicitly at program end (M17, M30). The NC program is only decoded but no axis positions are interpolated. This permits long NC program to run through quickly.

When program end is reached, the complete NC program is terminated in block search mode.

Distinction from “Dry Run”

In Dry Run [FCT-C17] mode the processing speed is identical to execution on the machine. Axis positions are interpolated but axis motions are not executed. This operation mode is only useful if it is executed directly on the machine controller.
