In this scenario, when the start button is pressed and released, the operation sequence specifies that M2 starts first and runs for a duration of 2 minutes before M1 begins operating. This indicates that there is a specific sequence designed for the operation of these motors, which may be governed by control logic or operational requirements.

Starting with M2 allows for possibly managing load or system stability, particularly if M1 draws a significant current that could affect the startup of M2 if they were both to start simultaneously. Additionally, the time delay of 2 minutes for M2 ensures that it is fully operational before M1 is engaged, which may help in scenarios where there's a need for staggered loads or to reduce startup current surges.

This indicates a thoughtful design in the control logic, emphasizing the need for careful handling of electrical components to ensure that they operate within safe parameters without overloading the circuit or compromising performance. Thus, the choice of M2 to start first for a designated period before engaging M1 is key to understanding the operation sequence in this context.
