MEMORY MODE
[Function]
MEMORY mode of automatic operation is selected.
In this mode of operation, automatic operation is based on programs stored in the memory.
[Operation]
• MEMORY mode is selected when MEMORY mode signal (MEM) turns ON.
• The program is started with the "Auto operation "start" command" signal (ST).
• If the automatic operation mode is duplicated or canceled during automatic operation, the NC
alarm "M01 OPERATION ERROR 0101" will occur, and the block will stop.
• If the manual operation mode is entered or the program is duplicated with the manual operation
mode during automatic operation, the NC alarm will occur, and automatic operation will stop.
However, the manual and automatic programs can be duplicated if manual/automatic
simultaneous operation is valid.
(Note 1) Even when operation mode is other than automatic operation, illegal mode, if selected,
causes operation error.
