Fig. 4-33 Program correction display
The block with the breakpoint or error is highlighted (N15 in the figure). If an
error causes the program to be interrupted, the advance decoding is interrupted
before the block containing the error. You can edit the block with the error and
all the following blocks.
If the error is detected only during processing (e.g. error in tool radius
compensation), the defective block is not marked; it is possible to detect this
via the block number in the alarm.
Neither is the block marked, nor is the block number displayed in the alarm.
If necessary, complete the relevant program section with block numbers and
start the program again.
If a program is interrupted by a CANCEL alarm, execution of the program can
be continued from the breakpoint by pressing NC START after the program
error has been eliminated. When you press the CANCEL key you acknowledge
the error message.
If a program is interrupted by a RESET alarm, the program can only be started
after the RESET key is pressed. Execution begins from the start of the
program.
After a RESET interruption, you can use the block search function to calculate
the breakpoint and go to this point. This means the complete program does not
have to be processed (see the section "Block search").
