Which statement about the TIMER instruction is true?

• A. The cursor remains on the TIMER instruction line during execution.
• B. The TIMER can exceed 100 seconds.
• C. The TIMER always resets the robot position.
• D. The TIMER ignores vacuum and tool changes.

Answer: (A)

The TIMER instruction is a blocking delay in the program. When it runs, the robot waits for the specified time, and the program cursor stays on the same TIMER line during that wait. That behavior is why the statement about the cursor remaining on the TIMER instruction line is true—the system doesn’t advance to the next line until the delay finishes.

The timer’s job is simply to pause the sequence; it does not move the robot, reset its position, or automatically perform/tool changes. So it won’t reposition the arm or return to a home pose by itself, and it won’t inherently handle or ignore vacuum or tool changes—the timing is just a pause, with other actions governed by separate instructions.

Regarding duration, the timer is a finite, defined delay, not a mechanism for indefinite or unconstrained waiting. The idea that it can exceed a long threshold like 100 seconds isn’t consistent with how the timer is typically used in practice.
