22. TWO–PATH CONTROL
FUNCTION
487
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. This function is called the paths
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)
