SEARCH & START
[Function]
This signal is input into the controller when executing operation search in the memory mode and
carrying out automatic start up.
[Operation]
If this signal is input when the memory operation mode is selected, an operation search of the
machining program with the designated No. (R938/939) will be carried out. After the search, the
program will be automatically started.
If this signal is input during automatic operation, the program will be reset before the search. After
the resetting is completed, the search and automatic start operations will be executed.
Hold the search & start signal until the search & start (start) signal turns ON.
(Example) The O900 machining program is designated and search & start is executed in a state
other than automatic operation.
