Finding a start block
Mid-program startup means entering into an NC program at a selected
point. In smart.Turn programs you can start the program at any
NC block.
The MANUALplus starts program run from the cursor position. The
starting position is not changed by a previous graphic simulation.
The selected NC block is the first block run after the mid-program
startup. In the search for a start block, the MANUALplus brings the
machine into the situation in which it would be in a normal program run
just before the startup block. First the tool is selected, then the axes
are positioned in the configured sequence, and finally the spindle is
switched on.
 The MANUALplus must be prepared by the machine
tool builder for the mid-program startup function (PLC).
 HEIDENHAIN recommends starting at an NC block
immediately after a T command.
Please note:
 Position the slide with the following conditions:
 The turret can tilt without collision.
 The axes must be able to move to the last
programmed position without collision.
 If a T command is used as the starting block, the turret
moves first to the previous tool and then to the tool
selected in the starting block.
