Note 1. Programs can be continued even after the following operations. Before
continuing the program operation, be sure to confirm that existing condi-
tions will not cause any problem. If continuous program operation causes
a problem, do not continue the program; instead create the ladder program
so that the program will be executed from the beginning.
a) Program operation running under the Automatic Mode was stopped in-
tentionally or came to a stop by itself.
Examples:
b) Manual commands were executed in Manual Mode.
Examples:
c) The Cycle Start Bit was turned ON to continue operation after return-
ing to Automatic Mode.
For example, the following type of operation is possible:
The program can be temporarily suspended while moving to X10000 and
stopped at a position before the demand position, e.g., X500. The mode
can then be changed to Manual Mode and an origin search executed. After
the origin search has been completed, the mode can be changed back to
Automatic Mode to continue program operation. The program will continue
the move operation to X10000.
The Cycle Start Bit was turned OFF.
An error occurred.
An origin search was executed.
Jogging was executed.
A servo lock was executed.
