What is the difference between Alarm Acknowledge and Reset in FANUC control?

• A. Acknowledge logs awareness of the alarm; Reset clears the fault and allows operations to resume.
• B. Acknowledge clears the fault; Reset restarts the control system.
• C. Acknowledge redefines the fault condition; Reset stores the fault for later.
• D. Acknowledge ignores the alarm; Reset shuts down the robot.

Answer: (A)

In FANUC controls, alarm handling separates recognizing an alarm from clearing it. Acknowledge is used to tell the system you’ve seen the alarm and want to proceed with inspection or correction; it silences the alert and logs that you’re aware of the issue, but the fault itself remains active. Reset, on the other hand, actually clears the fault so the controller returns to a ready state and operations can resume once the underlying cause has been addressed. So you acknowledge to log and acknowledge the event, then you reset to remove the fault and continue, after ensuring everything is safe and the problem is resolved.
