low moment of inertia and/or a small load moment.
In operation modes 10 to 15, it cannot be ruled out that a wrong direction of rotation is determined
in quick synchronization. For example, a frequency not equal to zero may be determined although
the drive is at a standstill. If there is no overcurrent, the drive is accelerated accordingly. The
direction of rotation is defined in operation modes 11, 14 and 15.
The synchronization changes the parameterized starting behavior of the selected configuration. First,
the start command activates the search run in order to determine the rotary frequency of the drive.
