Which type of machine stop function requires a power-up procedure to restart the machine's operation?

The emergency stop function is designed to halt machine operations immediately in case of a critical situation that could pose safety risks to operators or equipment. When an emergency stop is activated, it disconnects power and generally locks out the machine system to ensure safety. As a safety measure, to prevent unintended restart after such an interruption, the machine must go through a power-up procedure before operations can resume. This can include steps such as ensuring the area is clear, monitoring system indicators, and potentially requiring manual intervention to reset certain safety protocols.

In contrast, other stop functions like push button stop, normal stop, and service stop may allow for a more straightforward resumption of operations without engaging a power-up procedure. The intent of these different types of stops is to provide varying levels of control over machine operations, with emergency stops specifically focusing on immediate safety and requiring a more involved restart process.
