You can use the block search functions to reach a breakpoint in a program (e.g.
after a program error, tool break, etc.). This causes the program to be decoded
until the breakpoint is reached. It is not necessary to process the entire
program.
If the position at the breakpoint has been left in JOG mode (e.g. during a tool
change), you can use the JOG/handwheel or REPOS function to travel back to
the position.
