What is the initial step in cycling power from the teach pendant?

The initial step in cycling power from the teach pendant requires the teach pendant to be ON. This is crucial because the teach pendant serves as the primary interface for operators to communicate with the robotic system. When the pendant is on, it allows the user to access critical functions such as diagnostics, programming, and initiating various controls necessary for safe operation.

Having the teach pendant on ensures that the system is in a state where it can receive and execute commands. This is especially important when cycling power as the pendant needs to be actively engaged to monitor the system status and read any error messages or alerts that may occur during the power cycle process.

In contrast, turning off the teach pendant (as suggested in one of the alternatives) would result in losing the ability to control the robot effectively. Rebooting the controller or engaging the emergency stop are actions that typically follow or are part of troubleshooting or emergency procedures, but they are not the initial requirement for cycling power. Thus, ensuring that the teach pendant is ON is the right first step in this process.
