If the teach pendant locks up on the opening screen, what is the first step in troubleshooting?

When the teach pendant locks up on the opening screen, the first step in troubleshooting should focus on addressing potential power and connection issues, which makes cycling the controller power a logical first approach. Resetting the power can help in clearing temporary faults or software glitches that may be causing the issue. This can restore functionality without immediately resorting to more drastic measures like replacing components.

By cycling the power, you allow the system to restart and reinitialize both the teach pendant and the controller, which can resolve many common issues that prevent the teach pendant from operating correctly. It’s an effective way to ensure that any transient errors are cleared, allowing for a fresh start.

Other options, such as replacing the teach pendant, may not be the most efficient first step considering it could be a software or connection-related problem. Likewise, checking connections may be necessary if the power cycle does not resolve the issue, but it typically requires more time than simply rebooting the system. Rebooting the robot is similar to cycling power but may not address potential issues with the teach pendant specifically. Thus, cycling the controller power is the most effective and immediate troubleshooting step to take.
