5.1.15 REFERENCE POINT LAMPS
These lamps indicate that the tool is positioned
on the reference point.
They light when the tool
is brought to the reference point through the
manual or automatic return to reference point
( G28) , or by the reference point return check
(G 27) , and goes out as the tool moves away from
the reference point by a subsequent operation.

5.1.18
DRY RUN SWITCH
Turning on the DRY RUN switch in the TAPE,
MDI or MEM mode causes the tool to move at the
speed selected by the
JOG FEED RATE switch,
ignoring all programmed F–functions.
F com-
mands can be displayed as they are programmed.
This switch may be used to check the program.
Rapid traverse ( GOO) rate for dry run operation
can be set by setting parameter # “6006D2. “
5.1.16 SINGLE BLOCK SWITCH
With this switch turned on, individual block-by-
block operation is obtained. A block of data is
executed each time the CYCLE START pushbut–
ton is activated.
In the automatic operation
mode, the machine stops by turping on this
switch after finishing the current block.

5.1,17 OPTIONAL BLOCK SKIP SWITCH
This switch selects whether the data in blocks
including a “/” is disregarded or not.
(1) While the switch is on, all the commands in
a block programmed after a “ /” are neglect-
(2)
ed.
However, block data appearing before
the “ /” remains effective.
While this switch is off, blocks including a
“/” are executed along with other blocks.
This switch is ineffective on the block under
execution and blocks stored in the advance–
reading buffer.
When this switch is turned
on during an automatic operation cycle, it
works on the block read after the switching
on has occured.
