What happens when the HOLD button is pressed during a program?

When the HOLD button is pressed during a program, the correct outcome is that the program stops and SERVO power is disabled. This action is crucial in various automated systems, particularly those involving motion control or robotics. By stopping the program and disabling SERVO power, the system ensures that there is no unintended movement or action that could lead to accidents or equipment damage while the system is in a hold state. This safeguards the overall operation and allows for safe maintenance or troubleshooting without the risk of the machine unexpectedly moving or operating.

In the context of operation, pressing the HOLD button is intended to pause all processing and prevent any further commands from being executed until the situation is stabilized or the button is released. This is essential in environments where safety is a concern, as it allows for human intervention or monitoring without the complication of machine activity.
