Assuming that the program was interrupted at block N40. When restart
function is activated, the controller will calculate the coordinate change from
N10 to N30, then move the tool to the end of N30 and continue the program
execution from there.

• Program Restart –2 (C012~C013)
Bits C012~C013 are also used to restart the program from where the execution was
interrupted. They are applied to the case when you interrupt the execution of the 1

program and jump to the 2
nd
program. Once you finish the 2
nd
program, you can use
C012~C013 to go back to the 1
st
program and restart from where it was left. The
procedures are as follows:
1. When program #1 is interrupted, C012=1 and the interrupted block number is
stored.
