  • ALARM causes the machine to stop.

  • FEEDHOLD displays the message Tool Overload and the machine stops in a feedhold situation. Press any key to clear the message.

  • BEEP causes an audible noise (beep) from the control.

  • AUTOFEED causes the control to automatically limit the feedrate based on the tool load.

note: When tapping (rigid or floating), the feed and spindle overrides are locked out, so the AUTOFEED setting is ineffective (the control appears to respond to the override buttons, by displaying the override messages).
caution: Do not use the AUTOFEED setting when thread milling or auto reversing tapping heads, as it can cause unpredictable results or even a crash.

The last commanded feedrate is restored at the end of program execution, or when the operator presses RESET or turns OFF the AUTOFEED setting. The operator can use FEEDRATE OVERRIDE while the AUTOFEED setting is selected. These keys are recognized by the AUTOFEED setting as the new commanded feedrate as long as the tool load limit is not exceeded. However, if the tool load limit has already been exceeded, the control ignores FEEDRATE OVERRIDE.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
