How do you clear all ERROR messages?

• A. Press ENTER
• B. Press START
• C. Turn off power
• D. The CANCEL key

Answer: (D)

When an ERROR message appears on a Motoman controller, you clear it by using the CANCEL key. Pressing CANCEL acknowledges the alert, dismisses the error dialog, and returns you to the previous screen so you can review the error code and status or proceed after addressing the issue. This is the designed way to clear on-screen errors without affecting the actual hardware state.

Pressing ENTER would typically confirm a selection but isn’t specifically for clearing errors. START would begin a motion or task and could be unsafe while an error is present. Turning off power is a drastic reset that stops everything but isn’t the normal way to clear an error and can hide the fault without resolving it. So, the CANCEL key is the correct method to clear the error message, after which you should diagnose and correct the underlying fault before retrying.
