Figure 5-4 Conditional wait in path controlled operation with three involved channels (schematic)
Example: WAITMC and read-in disable
M555 is output in channel 3 while the axis is traversing and generates a read-in disabled
(RID). Because the WAITMC is added to block N312, the wait marker is set and channel 2
continues to travel. The read-in disable causes the program processing in channel 3 to stop.
Note
For active G64, a WAITMC(...) block does not create its own block but is added to the
previous block. A drop in velocity must be prevented when continuous-path mode is active. A
WAITMC is therefore fulfilled if the preceding block is halted, e.g. by a read-in disable.
