Bi: Flying Restart Enable Signal Source / Fly_Res Enab S_Src; Flying Restart Search Current / Flyrest I_Srch - Siemens SINAMICS G150 Manual

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).
Refer to: p1201
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.
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 "power-on" is the first power-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).

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.

Flying restart search current / FlyRest I_srch

VECTOR_G Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: PEM, 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 prevailing search current is set dependent upon the
frequency on the basis of voltage inputs.
Reducing the search current can also improve flying restart performance (if the system moment of inertia is not very
high, for example).
