SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 01/2011
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, 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).
Description: Displays the status for checking and monitoring flying restart states in the U/f control mode.
