Description: Sets the operating mode for flying restart.
The flying restart allows the drive converter to be switched on while the motor is still rotating. In so doing, the drive
converter output frequency is changed until the actual motor speed/velocity is found. The motor then accelerates up
to the setpoint at the ramp-function generator setting.

Dependency: The ground fault test is only possible when the motor is stationary, and is therefore only realized when flying restart is
deactivated (p1200 = 0).
For induction motors, the following applies:
A differentiation is made between flying restart for U/f control and for vector control (p1300).
Flying restart, U/f control: p1202, p1203, r1204
Flying restart, vector control: p1202, p1203, r1205
For synchronous motors, the following applies:
Flying restart is not possible with U/f control or if, in the case of sensorless vector control, a Voltage Sensing Module
(VSM) has not been connected and parameterized.
If two VSMs are connected to the Motor Module, then the motor voltage for the flying restart is measured using the
second VSM (see p0151[1]).
If only one VSM is connected, then this can be used for the flying restart (p1200) (for induction motors, also see
p0247 bit 5). When activating flying restart, line synchronization must be deactivated (p3800 = 0).

Notice: The "flying restart" function must be used in cases where the motor may still be running (e.g. after a brief line supply
interruption) or is being driven by the load. The system might otherwise shut down as a result of overcurrent.
It does not make sense to use "flying restart" together with the "motor holding brake function" (p1215 > 0) because
then the flying restart will always be realized with the motor stationary.
For a flying restart of induction motors without voltage measurement (VSM) the de-energization time (p0347) must be
set long enough so that for fast restarts after a pulse inhibit, excessively high current peaks do not occur.
Note: For p1200 = 1, 4, the following applies:
Flying restart is active after faults, OFF1, OFF2, OFF3.
For p1200 = 2, 5, the following applies:
The "switch-on" is the first switching-on operation after the drive system has been booted. This is practical for motors
with a high-inertia load.
For p1200 = 1, 2, 3, the following applies: The search is made in both directions.
For p1200 = 4, 5, 6, the following applies: The search is only made in the setpoint direction. For a setpoint of zero, a
search is not made in the negative direction of rotation.
For operation with encoder, the following applies:
p1200 = 1, 4 as well as p1200 = 2, 5 and p1200 = 3, 6 have the same meaning.
For U/f control (p1300 < 20), the following applies:
The speed can only be sensed for values above approx. 5 % of the rated motor speed. For lower speeds, it is
assumed that the motor is at a standstill.
If p1200 is changed while commissioning (p0009, p0010 > 0), then it is possible that the old value will no longer be
able to be set. The reason for this is that the dynamic limits of p1200 have been changed by a parameter that was set
when the drive was commissioned (e.g. p0300).
