{ 0 }
This function is required to connect the FI to already rotating motors, e.g. in fan drives. Motor
frequencies >100Hz are only picked up in speed controlled mode (Servo mode P300 = ON).
0 = Switched off , no flying start.
1 = Both directions , the FI looks for a speed in both directions.
2 = Setpoint value direction , searches only in the direction of the setpoint val. which is present.
3 = Both directions after failure , as for { 1 }, however only after mains failure or fault
4 = Setpoint direction after fail , as for{ 2 }, however only after mains failure or fault
NOTE: For physical reasons, the flying start circuit only operates above 1/10 of the nominal
motor frequency (P201), however, not below 10Hz.

NOTE:
PMSM
: The catch function automatically determines the direction of rotation. The
device therefore behaves in an identical way to function 1 with the setting for
function 2. The device behaves in an identical way to function 3 with the setting for
function 4.
In CFC closed loop operation, the catch circuit can only be executed if the rotor
position is known in relation to the incremental encoder. For this purpose, the motor
can initially not rotate when it is switched on for the first time after a "mains on" of
the device.

This restriction does not apply if the zero track of the incremental encoder is used.

NOTE:
PMSM
: The flying restart does not function if fixed pulse frequencies (setting 16.2
and 16.3 ) are used in P504 .

S P
0.02... 2.50 Hz
{ 0.05 }
Using this parameter, the flying start circuit search increment size can be adjusted. Values that
are too large affect accuracy and causes the FI to cut out with an overcurrent message. If the
values are too small, the search time is greatly extended.

{ 0.0 }
A frequency value that can be added to the frequency value found, e.g. to remain in the motor
range and so avoid the generator range and therefore the chopper range.

Factory setting
(Factory setting)
0 ... 2
{ 0 }
By selecting the appropriate value and confirming it with the ENTER key, the selected parameter
range is entered in the factory setting. Once the setting has been made, the value of the
parameter returns automatically to 0.
0 = No change: Does not change the parameterisation.
1 = Load factory settings: The complete parameterisation of the FI reverts to the factory setting.
All originally parameterised data are lost.
2 = Factory settings without bus: All parameters of the frequency inverter with the exception of
the bus parameter, are reset to the factory setting.
