OPERATION
DRY RUN Used to check actual machine movement without cutting a part. Programmed
feeds are replaced by the speed keys in the handle jog row.
OPT STOP Turns on optional stops. If an M01 code is encountered in the program and OPT
STOP is on, a stop is executed. Depending on the lookahead function, it may not
stop immediately. If the program has been interpreted many blocks ahead, and
OPT STOP is pressed, then the nearest M01 may not be commanded. See G103.
1. OPT STOP will take effect on the line after the highlighted line when OPT
STOP is pressed.
2. M01 is not allowed during cutter compensation. Alarm 349 will be gener-
ated in this case, as for M02, M30, and M00.
BLOCK Blocks with a slash ("/") as the first item are ignored or not executed when this
DELETE option is enabled. If a slash is within a block, address codes after the slash will
be ignored until after the block, if this option is enabled.
1. When not in cutter compensation, block delete will take effect two lines
after BLOCK DELETE is pressed.
2 When in cutter compensation, blocks must be processed earlier. There-
fore, block delete will not take effect until at last four lines after the
highlighted line when BLOCK DELETE is pressed.
3 If BLOCK DELETE changes state during the processing of the first block
of a chamfering/rounding pair, and at least one of the pair is block-
deleted, the behavior is undefined.
4 Processing will slow down for paths containing block deletes during
high-speed machining, because the lookahead queue will be emptied
as processing approaches the block-deleted line(s). This limits the
speed at which the previous blocks can run.
MDI/DNC Selects MDI or DNC mode.
COOLNT Turns the coolant on and off.
ORIENT Rotates the spindle to a known position and then locks the spindle.
SPINDLE Can be used during setup to indicate parts.
ATC FWD Rotates the tool turret forward to the next sequential tool. If Tnn is in
the input buffer, the turret will advance to tool nn. Except on CE machines.
ATC REV Rotates the tool turret backwards to the previous tool. If Tnn is in the
input buffer, the turret will advance to tool nn. Except on CE machines.
