Which practice is most essential when testing a program for the first time?

• A. Make sure all personnel are outside the work envelope before running
• B. Use low motion speed, to single step the program through at least one cycle
• C. Calibrate all frames used in the program
• D. Calibrate all tools used in the program

Answer: (A)

Testing a program for the first time carries the highest risk of unexpected robot motion due to programming mistakes or misconfigurations. The most essential safety step is making sure all personnel are outside the robot’s work envelope—the space the robot can reach during its movements. If someone is within that area, even a brief, unanticipated move can cause injury. Keeping people clear removes the immediate hazard and protects anyone who might be nearby during the initial, unverified run. Other practices help with safety and debugging, but they don’t address the core risk as directly. Running at a slow speed or stepping through a cycle can reduce exposure, yet a fault could still cause sudden movement toward someone in range. Calibrating frames or tools improves accuracy, but it doesn’t mitigate the danger posed by an unforeseen robot motion during the first test.
