If the power module receives a startup command when it cannot be started, the startup
command will be kept for 1 minute. Within 1 minute, if there is no situation (for example,
the power module encounters other faults, executes a shutdown command, or a fault is
rectified) that requires the startup command to be cleared and the power module becomes
able to start, then the power module responds to the startup command.
