How does the WAIT command function in FANUC instructions?

The WAIT command in FANUC instructions is designed to control program execution by pausing until a specified condition is satisfied. This can be particularly useful in situations where synchronization with external devices or specific sensor conditions is required. For instance, the command can ensure that a machine tool does not proceed to the next step of a program until a particular input signal indicates readiness, such as a part being in the correct position or a safety interlock being released.

The functionality of the WAIT command contrasts with commands that simply introduce delays or manage timers, which do not take real-time conditions into account. Therefore, it is essential to understand the distinct operational focus of the WAIT command, which emphasizes conditional execution rather than mere timing.
