8. AUXILIARY FUNCTION
995
Control based on M codes is used to cause one path to wait for the other
during machining. By specifying an M code in a machining program for
each path, the two paths can wait for each other at a specified block. When
an M code for waiting is specified in a block for one path during automatic
operation, the other path waits for the same M code to be specified before
staring the execution of the next block.
A range of M codes used as M codes for waiting is to be set in the
parameters (Nos. 8110 and 8111) beforehand.
[Classification] Input signal
[Function] Specifies whether to synchronize the paths by the waiting M code.
[Operation] When this signal turns to “1” the paths are not synchronized by the M
code. The M code for waiting specified in a machining program is
ignored.
When this signal turns to “0”, the paths are synchronized by the M code.
When the M code for waiting is specified for one path, the CNC waits for
the corresponding M code of another path to be issued, then starts
executing the next block.
[Classification] Output signal
[Function] Indicates that the CNC is waiting for the M code of either path 1 or 2.
[Output condition] This signal is “1” as long as:
D One path is waiting for another path. That is, the signal stays “1” for
the period from when the M code for waiting is issued to one path to
when the corresponding M code is issued to another path.
This signal is “0” as long as:
D Neither of the paths are waiting for the other.
