Autochange function (change of start order) makes the wear of the motors in the system
more equal. Autochange function monitors the running hours and sets the start order of
each motor. The motor that has the lowest running hours starts first and the motor that has
the highest running hours starts last. You can configure the autochange to start based on the
autochange interval time or on the internal real time clock of the drive (an RTC battery
needed).
