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 operation with encoder, the following applies:
p1200 = 1, 4 as well as p1200 = 2, 5 and p1200 = 3, 6 have the same meaning.
For V/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).
Description: Sets the search current for the "flying restart" function. The value is referred to the motor magnetizing current.
Dependency: Refer to: r0331
Caution: An unfavorable parameter value can result in the motor behaving in an uncontrollable fashion.
Note: Reducing the search current can improve the flying restart performance (if the system moment of inertia is not very
high).
Description: 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.
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, the motor is not found, e.g. for motors, that
are accelerated as a result of active loads we recommend that the search rate is reduced (by increasing p1203).
