5. AUTOMATIC OPERATION
187
A program may be restarted at a block by specifying the sequence number
of the block, after automatic operation is stopped because of a broken tool
or for holidays. This function can also be used as a high–speed program
check function.
There are two types of restart methods.
P type: Restart after a tool is broken down
Q type: Restart after holidays
[Classification] Input signal
[Function] Selects program restart.
[Operation] When the program restart signal is set to “1” to search for the sequence
number of the block to be restarted, the CRT screen changes to the
program restart screen. When the program restart signal is set to “0”, and
automatic operation is activated, the tool is moved back to the machining
restart point at dry run speed along the axes one by one in the sequence
specified in parameter No. 7310. When the tool is set to the restart point,
machining restarts.
[Classification] Output signal
[Function] Indicates the program is being restarted.
[Output condition] The program restart under way signal becomes “1” when:
– The program restart signal is set to “0” after the CRT screen changes
to the program restart screen.
The signal is set to “0” when:
– The program restart sequence ends (the tool has been moved to the
restart point on all controlled axes).
