Read: Understanding G27, G28, G29 and G30Īgain, the machine will be in an alarm state if a #3000 command is executed, and the operator must eventually press the reset button to clear the alarm. As with the stop with message command, the number (100) provides a way to further document, and the information in parentheses can be as long as 26 characters and is exactly as it will be displayed on the message screen.
The “MC” tells the operator that this is a macro alarm (as opposed to a program storage alarm, over-travel alarm or servo alarm ). If it is not, an alarm sounds and this message is displayed on the alarm screen: This creates a test that confirms that the Y axis is at its zero-return position. If #5022 is not zero, the machine is not at the Y-axis zero-return position. It so happens that system variable #5022 monitors the current Y-axis position relative to zero return. Maybe there is a tall obstruction on the table that would interfere with the tool-changing system if the Y axis is not at its zero-return position.
Say, for example, the programmer wants to confirm that the Y axis is at the zero-return position before a tool change. If a condition exists that would cause a problem, the programmer can stop the program and put the machine in alarm state. The alarm-generation command is most often used with some kind of decision-making, using the custom macro’s IF statement. The operator cannot force the machine to continue executing the program. As with any FANUC alarm, once the alarm is diagnosed, the operator must press the reset button in order to cancel it. The format for #3000 is the same as for #3006, but instead of simply stopping the program, this command places the machine in alarm state. The operator can restart the cycle by pressing the cycle start button.Īnother program-stopping command is the alarm-generating command, specified by system variable #3000. Again, the stop with message command will cause the machine to stop and show the message on the display screen. The “MS” stands for message and lets the operator know this is a stop with message condition. 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.
#MAZAK ALARM CODES MANUAL#
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.
