(1)When soft key [CLEAR] is pressed, followed by soft key [EXEC], all
the set data is cleared. In this case, however, the G codes are set to G00
or G01, depending on the setting of bit 0 (G01) of parameter No. 3402.
Data can also be cleared by pressing the
RESET
key on the MDI panel.
(2)If soft key [CLEAR] is pressed during execution, an
”EXECUTION/MODE SWITCHING IN PROGRESS” warning is
output.
If one of the following occurs during execution, execution is halted, and
the data is cleared in the same way as when soft key
[CLEAR] is pressed.
The remaining distance to be traveled is canceled.
(1) When a feed hold is applied
(2) When the mode is changed to other than jog feed mode
(3) When an alarm is generated
(4) When a reset or emergency stop is applied
The M, S, T, and B functions remain effective even upon the occurrence
of the above events, with the exception of (4).
Modal G codes and addresses used in automatic operation or MDI
operation are not affected by the execution of commands specified using
the manual numeric command function.
When the tool is moved along an axis using a feed axis and
direction selection switch on the manual numeric command screen, the
remaining amount of travel is always shown as ”0”.
S codes cannot be specified in constant surface speed control mode.
While automatic operation is halted, manual numeric commands can be
executed. In the following cases, however, a ”START IMPOSSIBLE”
warning is output, and command execution is disabled.
(1)When an M, S, T, or B function is already being executed, a manual
numeric command containing an M, S, T, or B function cannot be
executed.
(2)When an M, S, T, or B function is already being executed, and that
function alone is specified or a block specifying that function also
contains another function (such as a move command or dwell
function) which has already been completed, a manual numeric
command cannot be executed.
When a manual numeric command is specified while the tool is being
moved along an axis by using a feed axis and direction selection switch,
the axial movement is interrupted, and the manual numeric command is
executed. Therefore, the tool cannot be moved along an axis by using a
feed axis and direction selection switch during execution of a manual
numeric command.
A mirror image cannot be produced for the direction of a specified axial
movement.
