What typically happens to M1 immediately if both motors start simultaneously from an idle state?

In the scenario where both motors start simultaneously from an idle state, M1 typically runs for a fixed duration as a part of its operational design, often governed by a timer or specific control logic incorporated in the system. This behavior is common in various industrial and automation applications where motors have programmed cycles or sequences for operational efficiency and safety.

The fixed duration is crucial because it allows for controlled operation, ensuring that M1 performs its intended task without risking overload or damage due to continuous operation or incorrect function. Such a setup might be used to coordinate processes where timing is essential, such as in manufacturing processes or equipment that requires synchronization.

For the other options, the motor remaining off until a reset or running continuously does not align with typical motor behavior when commanded to start under controlled conditions. Turning off and resetting does not correspond to the immediate action expected from M1 in this case, as it would usually execute its start sequence unless instruction dictates otherwise. Therefore, the understanding of M1's expected operation confirms that it is designed to run for a fixed duration following a simultaneous start command.
