p1201[0...n] BI: Flying restart enable signal source / Fly_res enab S_src
VECTOR_G Can be changed: T
Data type: Unsigned32 / Binary
P-Group: Functions
Not for motor type: REL
Min
-
Description: Sets the signal source to enable the "flying restart" function.
Dependency: Refer to: p1200
Note: Withdrawing the enable signal has the same effect as setting p1200 = 0.
p1202[0...n] Flying restart search current / FlyRest I_srch
VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: PMSM, REL
Min
10 [%]
Description: Sets the search current for the "flying restart" function.
The value is referred to the motor magnetizing current.
For U/f control, it may be necessary to increase the search current (e.g. 120 %) to ensure reliable flying restart.
Fast flying restart for induction motors with voltage model (see r1780.11):
Sets the initial setpoint for the field-generating current component.
Dependency: Refer to: r0331
Caution: An unfavorable parameter value can result in the motor behaving in an uncontrollable fashion.
Note: In U/f control mode, the parameter serves as a threshold value for establishing the current at the beginning of the
flying restart function. When the threshold value is reached, the actual search current is set as a function of the
frequency based on the voltage setpoints.
Reducing the search current can also improve flying restart performance (if the system moment of inertia is not very
high, for example).
The following applies for a synchronous reluctance motor:
- a parameter change only becomes effective after carrying out the motor data identification.
- the minimum search velocity is limited (p1202 >= 50 %).
- the search algorithm is optimized for 100 %, and the current reached is internally limited. A set value (p1202 != 100
%) cannot be reached.
p1203[0...n] 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: PMSM, 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.
Recommendation: 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.
