Flying restart search rate factor / FlyRst v_Srch Fact

VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: PEM, REL
Min
10 [%]
Description: Sets the factor for the search speed for flying restart.
The value influences the rate at which the output frequency is changed during a flying restart . A higher value results
in a longer search time.
Recommend.: For encoderless vector control and motor cables longer than 200 m, set the factor p1203 >= 300 %.
Caution: An unfavorable parameter value can result in the motor behaving in an uncontrollable fashion.
For vector control, a value that is too low or too high can cause flying restart to become unstable.
Note: The parameter factory setting is selected so that standard induction motors that are rotating can be found and
restarted as quickly as possible (fast flying restart).
With this pre-setting, if the motor is not found (e.g. for motors that are accelerated as a result of active loads or with
U/f control and low speeds), we recommend that the search rate is reduced (by increasing p1203).
This parameter is not relevant for a fast flying restart with voltage model (see r1780.11).
