SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
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 presetting, if the motor is not found (e.g. for motors that are accelerated as a result of active loads) we rec-
ommend that the search rate is reduced (by increasing p1203).
Description: Displays the status for checking and monitoring flying restart states in the V/f control mode.
