Example A production line must stop if something blocks the product belt, which
causes a motion error. The obstacle must be removed, and a reset but-
ton must be pressed to restart the line.

Example The position of an axis must be defined by the Z marker. This position
must be set to zero. Then the axis must move to this position. Using the
datum 1 the zero point is set on the Z mark. But the axis starts to decel-
erate at this point, and therefore it stops after the mark. A move is used
to bring it back to the Z position.
SERVO=ON
WDOG=ON
CREEP=1000 'set the search speed
SPEED=5000 'set the return speed
DATUM(1) 'register on Z mark and sets this to datum
WAIT IDLE
MOVEABS (0) 'moves to datum position
