SINAMICS G120D List Manual (LH14), 01/2013
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.
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: 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).
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.
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).
