Operator messages manual

Another program-stopping command is the alarm-generating command, specified by system variable The format for is the same as for , but instead of simply stopping the program, this command places the machine in alarm state. As with any FANUC alarm, once the alarm is diagnosed, the operator must press the reset button in order to cancel it. The operator cannot force the machine to continue executing the program.

If a condition exists that would cause a problem, the programmer can stop the program and put the machine in alarm state. Say, for example, the programmer wants to confirm that the Y axis is at the zero-return position before a tool change.

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. It so happens that system variable monitors the current Y-axis position relative to zero return.

If is not zero, the machine is not at the Y-axis zero-return position. In this case, consider these commands:. This creates a test that confirms that the Y axis is at its zero-return position.

If it is not, an alarm sounds and this message is displayed on the alarm screen:. As with the stop with message command, the number 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. Again, the machine will be in an alarm state if a command is executed, and the operator must eventually press the reset button to clear the alarm. Programmed messages give the operator the necessary guidance to get the machine to resume executing the program.

Tolerances of less than 25 microns can be challenging to achieve and hold. Here are some suggestions for holding them for multiple workpieces. Parameters tell the CNC every little detail about the specific machine tool being used, and how all CNC features and functions are to be utilized.

Cause Generated whenever a remote system is deleted from the local Subnet Database, or as part of an event delete or insert sequence to record a modification of an existing remote system entry.

Effect The corresponding remote system entry in the local Subnet Database is deleted or modified. Cause The MEU starts components during its initialization. Effect The affected MEU component is stopped, started, or reset.

A NonStop CPU which is power-cycled or reset while these services are unavailable will not boot properly. Contact HP support if connectivity loss appears permanent. Effect This generic MEU event is logged instead. Cause Generated whenever an MEU services a client request for a sensitive command.

Client at ip-address opened a session with MEUxx. Client at ip-address closed a session with MEUxx. MEUxx purged a session with client at ip-address. Cause The MEU purged a stale entry from its session table. MEUxx generated trace trace. MEU initialization events. Receives maintenance entity messages. NOTE: Negative-numbered messages are common to most subsystems.

If you receive a negative-numbered message that is not described in this chapter, see Chapter
