9.3.5 Operation Sequence for Program Restart

There are two types of restart, type 1 and type 2.
Restart type 1
When feed hold has been applied and reset because the tool has broken, etc., restart with restart type 1.
Press the feed hold button and retreat to the tool
change position by manual means or MDI.
Press the RESET key and suspend the present
processing.
Replace with a new tool.
Search the block to be restarted.
(Refer to "Executing Restart Search (Restart type 1)")
Turn the program restart switch ON.
Execute the manual numerical value command
(S,M,T,B)
(Refer to "Executing the MSTB Commands")
In the manual (JOG/rapid traverse) mode, move
the axes to the restart return position.
(Refer to "Returning to the Restart Position")
Turn the program restart switch OFF.
Return to the automatic operation mode.
Press the cycle start button.
Note
(1) When single block signal is OFF, the machining is restarted without stopping temporarily after the axes return to the
restart position. (The cycle starts when the automatic return by program restart is valid.)
(2) Execute "reset & rewind" for resetting.
(3) Restart search is not available for a program that has a file name consisting 33 or more characters.
