For our example, this message would be displayed: For most control models, the information in parentheses can be as long as 26 characters and is exactly as it will be displayed on the message screen. Like FANUC alarms, the number provides the programmer with a way to further document the message in a log book (separate from the machine) if additional explanation is necessary. With most FANUC control models, this value can range from 100 to 255. The value (100, in our example) is the message number. System variable #3006 commands the machine to stop. The format for the stop with message command is:Īgain, this command, like M00, is placed in the program whenever the programmer wants the machine to stop. With stop with message, the display will automatically switch to the message screen and show the message.

While a message in parentheses can be placed in close proximity to an M00 command, the operator would have to be monitoring the program in order to see it. Programmer can specify exactly what the operator is expected to do. The obvious advantage of the stop with message command is the message itself, as a

As with M00, the operator can press the cycle start button to reactivate the cycle. If the machine executes a #3006 command, it will stop and show a programmed message on the display screen. One program-stopping custom macro command, called “stop with message,” closely resembles the M00 program stop and is controlled by system variable #3006. They include an M00 program stop whenever the operator must perform a manual task during the CNC cycle, such as clearing chips, adding a tapping compound or reclamping the workpiece. Most programmers, for instance, include an M01 optional stop at the end of every tool so the operator can see what each tool has done before proceeding to the next tool.

These two machine-stopping commands are quite helpful and very important. One M code, the M00 program stop, will cause the machine to stop as planned, while another, the M01 optional stop, will cause it to stop when a switch is turned on. There are times when you need (or want) a CNC machine to stop executing a program.
