We cannot simply determine the finished start-up status by observing the motor
current. Therefore, it is possible to define by the setting [Mot-Start-IrrMode2],
whether the motor status is to be continued "Start-up" or change to "Running",
when the motor start-up time elapses.
b. Motor status transition for setting [Mot-Start-IrrMode2]=ChangeRun
Figure 2.28-5.a illustrates the motor status transition when ContStart is set for
the setting [Mot-Start-IrrMode2]. Even if the motor start-up time elapses, the
motor status is continued "Start-up".
b. Motor status transition for setting [Mot-Start-IrrMode2]=ChangeRun
Figure 2.28-5.b illustrates the motor status transition when ChangeRun is set for
the setting [Mot-Start-IrrMode2]. After the motor start-up time has elapsed, the
motor status is changed to "Running".
