The coordinates and amount of travel for restarting the program can
be displayed for up to five axes. If your system supports six or more
axes, pressing the [RSTR] soft key again displays the data for the
sixth and subsequent axes. (The program restart screen displays only
the data for CNC–controlled axes.)
M: Fourteen most recently specified M codes
T: Two most recently specified T codes
S: Most recently specified S code
B: Most recently specified B code
Codes are displayed in the order in which they are specified. All
codes are cleared by a program restart command or cycle start in the
reset state.
6 Turn the program re–start switch OFF. At this time, the figure at the
left side of axis name
DISTANCE TO GO blinks.
7 Check the screen for the M, S, T, and B codes to be executed. If they
are found, enter the
MDI mode, then execute the M, S, T, and B
functions. After execution, restore the previous mode.
These codes are not displayed on the program restart screen.
8 Check that the distance indicated under
DISTANCE TO GO is correct.
Also check whether there is the possibility that the tool might hit a
workpiece or other objects when it moves to the machining restart
position. If such a possibility exists, move the tool manually to a
position from which the tool can move to the machining restart
position without encountering any obstacles.
9 Press the cycle start button. The tool moves to the machining restart
position at the dry run feedrate sequentially along axes in the order
specified by parameter settings (No. 7310). Machining is then
restarted.
When the CNC is stopped, the number of executed blocks is displayed on
the program screen or program restart screen. The operator can specify
the number of the block from which the program is to be restarted, by
referencing the number displayed on the CRT. The displayed number
indicates the number of the block that was executed most recently. For
example, to restart the program from the block at which execution
stopped, specify the displayed number, plus one.
The number of blocks is counted from the start of machining, assuming
one NC line of a CNC program to be one block.
