5. Key in the desired character string or sequence number to search for
and press the
[TRANSMIT] key. The control locates an @ symbol to
the left of the block immediately before the block that automatic
execution begins from.
If this is not the block to begin execution from,
(softkey level 5)
CONT TOP OF
PRGRAM
QUIT EXIT
If you want to: Press this softkey:
continue to search for the entered character string or
sequence number {CONT}
return to the first block in the program {TOP OF PRGRAM}
end either the sequence number search or the character
string search operations {QUIT}
6. Press the {EXIT} or the {EXIT & MOVE} softkey once the program is
at the desired location.
{EXIT} - Use this softkey if the wheel is at the exact location for
execution of the searched program block. While the control searches
for your starting block it performs calculations to determine what the
absolute position of the axes should be before your selected block is
executed. If the wheel is not at this position when you press the
{EXIT} softkey, the control aborts the mid-start operation. When this
occurs the control displays the message “AXIS POSITION
INCORRECT”.
{EXIT & MOVE} - Use this softkey if the wheel is not at the exact
location for execution of the searched block. Be aware that the
absolute position of the axes necessary at the start of the searched
block is dependant on the previous blocks. There can be offsets
activated or incremental moves that can make it difficult for you to
determine the exact absolute starting point for the axes. The control
generates a motion block to place the wheel at the position necessary
to generate the intended contour when the searched block is
executed. The block generated is always a linear move with a
feedrate based on the last motion block prior to the searched block.
If the last motion block was a cutting move with a feedrate, then the
generated block will be a linear move at that cutting feedrate. If the
last motion block was a rapid move, that the generated block will be
a linear move at the rapid feedrate.
