21. TWO–PATH CONTROL
FUNCTION
371
Control based on M codes is used to cause one tool post to wait for the
other during machining. By specifying an M code in a machining
program for each tool post, the two tool posts can wait for each other at
a specified block. When an M code for waiting is specified in a block for
one tool post during automatic operation, the other tool post waits for the
same M code to be specified before staring the execution of the next block.
This function is called the tool post waiting function.
A range of M codes used as M codes for waiting is to be set in the
parameters (Nos. 8110 and 8111) before hand.
M100 to M103 are used as M codes for waiting.
Parameter setting: No. 8110= 100(Minimum M code for waiting:
M100)
No. 8111= 103(Maximum M code for waiting:
M103)
