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.
In operation modes 1 to 5, the
Current / Rated Motor Current
647 is used for synchronization as a
percentage of
Rated Current
371 .

The sensorless control is extended for the search run by a compensated proportional regulator,
which regulates the parameterized
Current / Rated Motor Current
647 . The proportional and
integrating part of the current controller can be set via parameters
Amplification
648 and
Integral Time
649 . The control functions can be deactivated by setting the
parameters to 0.

If the
Operation Mode Synchronisation
645 parameter was set to operation mode 1 to 5 (search
run), the search run is not started before the
Demagnetizing Time
633 has elapsed.
If synchronization to the drive mechanism is not possible, the
Braking Current
631 is impressed
into the motor in operation modes 1 to 5 for the duration of the
Brak. Time after Search Run
646 .
The impression of the direct current set in the parameters of the direct current brake leads to a
heating of the motor and should only be done for a short period in internally ventilated motors
Parameter Setting

646 Brak. time after search run 0.0 s 200.0 s 10.0 s
NOTICE
The search run function is designed for operation with motors without brake. Brake
motors my not be operated perfectly with the search run function (depending on
parameterization and brake control.
